You will learn many new ideas like electricity in physics class 11. The current flow in metals is based on free electrons. In the absence of an electromagnetic field applied to the outside (using a battery), the free electrons move randomly through the metal from one point to another and cause a zero net current .

When connected to a battery, free electrons accelerate due to the electric field generated by the battery and gain speed and energy. However, the passage is not smooth and the electrons collide with the crosslinked ions whose final gain (energy) is the ion. Since we know that body temperature is related to the vibrational energy of these ions, these collisions cause the temperature of the metal to increase. The energy loss of the colliding electrons and their acceleration by the electric field ultimately causes the electrons to drift in a certain direction. (Although the actual movement of the electrons is irregular, the general effect is that the electrons drift.) In addition to this mechanics, the most important part of class 11 physics is where you learn that movement means changing position over time. When a body is at rest, its position does not change over time. But how to describe the position of a body? To do this, we must describe it in relation to another body as a reference.

Rest and movement are therefore relative. A man seated in a car traveling on the highway at 55 km / h is resting relative to a traveling companion while moving relative to a person standing on the highway.

To describe rest and movement, we select a frame of reference, and then describe rest or movement relative to that frame of reference.

There are two types of movements: transnational and rotational.

If a body moves in such a way that it always remains parallel to it throughout the movement, it is translated. When a body moves so that each point on the body maintains a constant distance from a fixed axis in space, the movement is a rotation.

Biology (Gk. Bios-life and logos-to speech) is the branch of science that deals with the scientific study of life. It depends on other sciences (such as physics and chemistry) and has therefore become a multidisciplinary and multidimensional scientific branch. Biology is better known as “life sciences” because it seeks to understand how living things interact with other “living” and “non-living” things.
Precisely, biology is research, an ongoing investigation into the nature of life. Biology, being an important branch of science, requires a scientific approach to understand and obtain precise results.

• The term “biology” was coined by Lamarck and Treviranus in 1802.
• Aristotle is known as “father of biology and zoology”.
• Theophrastus is known as the “father of botany”.
• Microorganisms were first observed by A.V. Leeuwenhoek but Louis Pasteur is considered to be the father of microbiology.

NCERT Solutions for Class 11 Biology Chapters:

Chapter 1: The Living World

Biology is the science of life forms and living processes. In nature there is sharing of similarities among living organisms both horizontally and vertically. That is all present-day organisms are related to each other and also to all organisms that ever lived on this earth.

Life is a unique, complex organization of molecules expressing itself through chemical reactions that lead to growth, development, responsiveness, adaptation, and reproduction.

 Chapter 2: Biological Classification

Since the dawn of civilization, there have been many attempts to classify living organisms. Aristotle was the first to attempt a more scientific basis for classification. He used simple morphological characters to classify plants as trees, shrubs, and grasses. He also divided the animals into two groups, those who had red blood and those who did not.

The art of identifying differences between organisms and classifying them into groups that reflect their most important properties and relationships is called biological classification. The aim of biological classification is to organize a large number of known plants and animals into categories that can be named, memorized, and studied.

Chapter 3: Plant Kingdom

Chapter 4: Animal Kingdom

Chapter 5: Morphology of Flowering Plants

Morphology - (Morphe = form + logos = study). The studies the forms and functions of various plant organs, such as roots, stems, leaves, flowers, seeds, fruits, etc.

Chapter 6: Anatomy of Flowering Plants

The Study of the internal structure of the body of an organism is known as Anatomy.

Higher plants have a highly complex body made up of different types of cells. All cells have the same origin but afterward they get differentiated into different types of cells.

A group of similar or dissimilar cells having a common origin, performing a speciliased function is known as tissue where all cells remain is physical contact.

Chapter 7: Structural Organisation in Animals

Chapter 8: Cell: The Unit of Life

Chapter 9: Biomolecules

Biomolecules is the study of chemical processes in living organisms, including, but not limited to, living matter. Biomolecules governs all living organisms and living processes. By controlling information flow through biochemical signaling and the flow of chemical energy through metabolism, biochemical processes give rise to the complexity of life.

Chapter 10: Cell Cycle and Cell Division

Growth and reproduction are properties of cells and indeed of all living organisms. All cells are multiplied by division into two, and each parent cell produces two daughter cells each time they divide. These newly formed daughter cells can grow and divide on their own, creating a new cell population formed by the growth and division of a single parent cell and its progeny. In other words, such growth and division cycles allow a single cell to form a structure of millions of cells.

Chapter 11: Transport in Plants

In a flowering plant the substances that need to be transported are water, mineral nutrients, organic nutrients, and plant growth, regulators.

Plants need to move molecules over very long distances, much more than animals and they also do not have a circulatory system.

Water taken up by roots has to reach all parts of the plant, up to the tip of stem and food synthesized by leaves also move to plants including root tips.

Movement across short distances, say within the plant cell, across the membranes and from cell to cell within the tissues also takes place.

Chapter 12: Mineral Nutrition

Mineral nutrition- It included absorption, distribution and metabolism of various inorganic substances or minerals by plants

Chapter 13: Photosynthesis in Higher Plants

Photosynthesis is the physio-chemical process by which solar energy is trapped by autotrophic organisms to drive the synthesis of organic compounds.

Chapter 14: Respiration in Plants

The word respiration is derived from the Latin word ‘respirare’ (literally) means to breathe. It was in the late eighteenth century that the chemistry of respiration was understood. The Dutch plant physiologist Jan Ingenhousz first established that living plants exchange oxygen and carbon dioxide with the external atmosphere

Chapter 15: Plant Growth and Development

Growth in plants, as in any organism, consists of an irreversible increase in size, which is commonly accompanied by an increase in solid or dry weight and in the amount of protoplasm. Growth is an essential character of life. In common practice, the term 'growth' may be applied to several things and situations.

Chapter 16: Digestion and Absorption

Chapter 17: Breathing and Exchange of Gases

Chapter 18: Body Fluids and Circulation

Chapter 19: Excretory Products and their Elimination

Chapter 20: Locomotion and Movement

Kinesiology is the scientific study of body movements. Most animals move about from one place to another by swimming, flying or walking. To move, all animals use the same basic mechanism: muscle contraction. Movement especially on land, is complicated by gravity which tends to hold objects in one place. Therefore, it becomes essential that a force is applied to overcome gravity. For a muscle to produce movement, it must direct its force against another object.

Chapter 21: Neural Control and Coordination

As we know, the functions of the organs/organ systems in our body must be coordinated to maintain homeostasis. Coordination is the process through which two or more organs interact and complement the functions of one another.

Chapter 22: Chemical Coordination and Integration

What is TAXONOMY?

  1. The word taxonomy was first used by A.P.de Candolle in 1813. It means a lawful arrangement of things. It is often considered as synonymous with systematic botany. It deals with the identification, nomenclature, and classification of plants.
  2. The terms systematics, Taxonomy and classification are often used interchangeably.
  3. G. Simpson has distinguished the three. (i.e., systematics, classification and taxonomy)
  4. The study of the diversity of organisms, their comparative and evolutionary relationships based on comparative anatomy, ecology, physiology, biochemistry and other fields is known as systematics. The term systematics was coined by Linnaeus (father of taxonomy)
  5. Classification – It is said to be a subtopic of taxonomy or systematics that deals with arranging organisms into groups or categories according to a systematic plan on the basis of their similarities, differences, and relationships.

About Chemistry Class 11 Notes

In chemistry class 11 you will learn more about the atom and its structure. Reactions and how to apply the concepts in balance. “The rich diversity in the chemical behavior of the various elements can be attributed to the differences in the internal structure of the atoms of these elements.”
Maharshi Canada [600 a. C.] The Indian philosopher suggested making matter out of small particles called Parmanu and Anu. Later in Democritus [400 a. C.], a Greek philosopher, also suggested that matter consists of extremely small particles, ie atoms are fundamental elements of the question.

The word “atom” is derived from the Greek word “a - thomium”, which means “that cannot be cut” or “not divisible”. These earlier ideas were only speculations and there was no way to test them experimentally.

John Dalton (1808-1809) could give old ideas or hypotheses a scientific basis by proposing his famous atomic theory called Dalton’s atomic theory, which regards the atom as the last particle of matter and as indivisible and indestructible.
In fact, the atom as a whole is electrically neutral because the number of protons it contains is equal to the number of electrons. Research shows that the atom can be divided into approximately 200 atomic sub-particles. The electron, proton and neutron are the main basic particles of an atom.
