STRUCTURAL ORGANISATION IN ANIMALS (1)

STRUCTURAL ORGANISATION IN ANIMALS | NCERT | BIOLOGY CHAPTER 7

In the preceding chapters you came across a large variety of organisms, both unicellular and multicellular, of the animal kingdom. In unicellular organisms, all functions like digestion, respiration and reproduction are performed by a single cell. In the complex body of multicellular animals the same basic functions are carried out by different groups of cells

ANATOMY OF FLOWERING PLANTS | NCERT | BIOLOGY CHAPTER 6

You can very easily see the structural similarities and variations in the external morphology of the larger living organism, both plants and animals. Similarly, if we were to study the internal structure, one also finds several similarities as well as differences. This chapter introduces you to the internal structure and functional organisation of higher plants.

MORPHOLOGY OF FLOWERING PLANTS

MORPHOLOGY OF FLOWERING PLANTS | NCERT | BIOLOGY CHAPTER 5

The wide range in the structure of higher plants will never fail to fascinate us. Even though the angiosperms show such a large diversity in external structure or morphology, they are all characterised by presence of roots, stems, leaves, flowers and fruits. In chapters 2 and 3, we talked about classification of plants based on

ANIMAL KINGDOM | NCERT | BIOLOGY CHAPTER 4

When you look around, you will observe different animals with different structures and forms. As over a million species of animals have been described till now, the need for classification becomes all the more important. The classification also helps in assigning a systematic position to newly described species. 4.1 BASIS OF CLASSIFICATION Inspite of differences

PLANT KINGDOM | NCERT | BIOLOGY CHAPTER 3

In the previous chapter, we looked at the broad classification of living organisms under the system proposed by Whittaker (1969) wherein he suggested the Five Kingdom classification viz. Monera, Protista, Fungi, Animalia and Plantae. In this chapter, we will deal in detail with further classification within Kingdom Plantae popularly known as the ‘plant kingdom’. We

CELL CYCLE AND CELL DIVISION | Chapter 10 | NCERT | NEET

Cell Cycle The sequence of events by which a cell duplicates its genome, synthesizes the other constituents of cells, and eventually divides into two daughter cells is called cell cycle. DNA synthesis occurs in one specific stage of cell division but the distribution of chromosomes in cells occurs in complex series of events during cell
