ICSE Class 7 Biology — Chapter Summary

Tissue is a group of similar cells that perform a specific function. Multicellular plants and animals are made of many kinds of tissues, and each tissue has a special job. Plant tissues are mainly of two types: meristematic tissue and permanent tissue. Animal tissues are classified into epithelial,

Classification is the system of grouping living organisms on the basis of common features. It makes the study of the huge variety of living things systematic and easier. In the living world, the earlier two-kingdom grouping created many anomalies, so a five kingdom classification was suggested.

Animals are grouped into two main categories based on the presence or absence of a backbone: invertebrates and vertebrates. Invertebrates are divided into eight phyla, while vertebrates are divided into five classes. This classification helps in identifying animals by their body structure, movement,
