NCERT Solutions Class 11 Biology Chapter Description and Details

Class 11 Biology consists of two parts one is zoology and the second is botany both parts are important for the CBSE board as well as competitive exams. Let us understand what are you going to learn from these chapters.

Biology Class 11 NCERT Solutions Chapter 2 Biological Classification

Fundamentals of animal classification

Levels of body organization-Following are the different levels of organization in animals from simpler to complex states:

1. Protoplasmic grade – In this grade, all life activities are confined within the boundaries of a single cell which is a structural and functional unit of life. e.g. Protozoa and other unicellular organism.
2. Cellular grade – It is a loose association or aggregation of cells that are functionally differentiated, e.g. sponges.
3. Tissue grade – An aggregation of cells which act in coordination. e.g. Cnidarians.
4. Tissue-organ grade – When tissues aggregate to form a particular organ. First appeared in Platyhelminthes.
5. Organ system grade – When organs work together to perform some common function such as digestion, respiration, circulation etc. e.g., most of the higher animals.

Body Plan

1. Cell Aggregate Body plan – The body is made up of cells (Aggregate) and each cell act almost independently. e.g. Porifera (sponges)
2. Blind Sac – The body resembles a sac and contains a single cavity with one opening that serves for ingestion and egestion e.g., Cnidaria (Hydra), Platyhelminthes (flatworms).
3. Tube within a tube – The body is made up of two tubes, the outer body wall and the inner digestive tract. e.g. Annelida

Biology Class 11 NCERT Solutions Chapter 5 Morphology of Flowering Plants

Flowering plants are multi-cellular organisms which grow by cell division. Their morphological features and traits are genetically determined. “Morphology is one of the most interesting branches of Biology and may almost be said to be its very soul”- Charles Darwin. Morphology plays a key role in the classification of plants. This unit includes the important morphological features, organization of body parts of the flowering plants, their internal structure and tissue system. In this unit, you will also learn how to describe a flowering plant, using examples from selected families, and how different organs of plants are modified to serve specific needs, including defense from their enemies. Some ideas about the economic importance of selected plant families can also be known.

Biology Class 11 NCERT Solutions Chapter 6 Anatomy of Flowering Plants

The study of the internal structure of plant parts, called anatomy includes histology, that is, the organization and structure of tissues, which compose the second level of organization of the plant body. Anatomy is not only useful in knowing the structural peculiarities of different groups of plants but also indicates the structural adaptations of plants to external stresses. It is also useful for knowing homology and analogy and that has solved several taxonomic problems.

Biology Class 11 NCERT Solutions Chapter 8 Cell The Unit of Life

The cell is the structural and functional unit of all living organisms. Cells within a single plant or animal vary widely in structure and function, they all represent units of living material and have important properties in common. Both plant and animal cells are essentially alike in terms of having the same type of organelles which functions in a very universal way and carry genes which pass the character of one generation to another generation.

Biology Class 11 NCERT Solutions Chapter 9 Biomolecules

The study of the living world shows that evolution has produced an immense diversity of forms. There are about four million different species of bacteria, protozoa, plants and animals that differ in their morphology, function and behaviors. The cell is the fundamental, structural, and functional unit of living organisms, just as the atom is the fundamental unit of matter. When living organisms are studied at the cellular and molecule levels there is a unique master plan of organization. Besides living things are composed of lifeless molecules cells are self-sufficient and autonomous but gradually become more dependent on another cell for their existence. The scope of cell and molecular biology is precisely that unifying organizational plan – in other words, the analysis of the cells and molecules constitute the building blocks of all forms of life.

Biology Class 11 NCERT Solutions Chapter 10 Cell Cycle and Cell Division

Life has an immense variety of forms that arose by the process of biological evolution but all living organisms share a master plan of structural and functional organization. The building blocks–cells and molecules bridge the diversity of the living world. Besides the cellular, chemical and molecular analogy, each type of cell organelle have the same function throughout the living world.. Cell and organelle have their internal environment distinct from the external environment. Biological membranes functions as boundaries between the external and internal environment of the cell. Organisms maintain homoeostasis at each level of the organization. Every cell requires energy for its working and maintenance of the organization. Energy is obtained by living cells from food molecules through aerobic and anaerobic respiration and liberated energy is trapped by ATP molecules, which are used for various cell functions. Thus life can exist and express itself only in the form of cells and so cell and molecular biology have become the basic pillars on which biological and medical sciences are based.

Biology Class 11 NCERT Solutions Chapter 18 Body Fluids and Circulation

Circulatory systems in various groups of animals can be classified as follows:

1. Intracellular circulation: Occurs inside the individual cells where the distribution of substances is through cyclosis of cell cytoplasm. Example – Protozoans.
2. Extracellular circulation: When the distribution of the substances occurs inside the body through extracellular or intracellular fluids. This is of the following types

a) Extra organismic circulation: When the water of the external environment circulates through the body. This is also called a water circulation system. Example – canal system in Porifera, water vascular system in Echinoderms and gastrovascular system in coelenterates.

b) Intra-organismic circulation: It involves the circulation of body fluids. It is of the following types:

1. Parenchymal circulation: In Platyhelminthes, the fluid-filled spaces present in the mesodermal parenchyma tissue between the body wall and internal organs are used in the distribution of substances.
2. Coelomic circulation: Coelomic fluid is concerned with the transport of substances. Example – pseudocoelomic fluid in the roundworms and haemolymph in Arthropods.
3. Blood vascular system: It contains blood and a pumping structure (heart) for the circulation of materials inside the body. It is of the following types:

1. Open circulatory system
2. Closed circulatory system
