CLASS 7 - BIOLOGY - CLASSIFICATION

What is classification?

Grouping living things based on how similar they are.

Why do scientists classify organisms?

To study them easily, identify them correctly, and understand how they are related.

What is a species?

A group of organisms that look similar, can mate with each other, and produce fertile offspring.

What is binomial nomenclature?

A two-word naming system for organisms, consisting of genus (capitalized) and species (lowercase).

What is the significance of using scientific names?

They provide a universal name to avoid confusion and are more accurate than common names.

What is the largest group in the levels of classification?

Kingdom

What does the mnemonic 'King Philip Came Over For Good Soup' represent?

The hierarchy of classification levels: Kingdom, Phylum, Class, Order, Family, Genus, Species.

What are the five kingdoms of living things?

Monera, Protista, Fungi, Plantae, Animalia.

What characterizes the kingdom Monera?

Simple, single-celled organisms without a nucleus, such as bacteria.

What are examples of organisms in the kingdom Protista?

Amoeba and Paramecium.

What defines the kingdom Fungi?

Organisms that cannot make their own food and feed on dead or living matter, like mushrooms and yeast.

What is a key feature of the Plantae kingdom?

Plants that make their own food through photosynthesis and usually do not move.

What distinguishes the Animalia kingdom?

Animals that cannot make their own food, can move, and have sense organs.

How are plants classified?

Based on the presence of flowers, seeds, and vascular tissue.

What are the two main groups of plants?

Flowering plants (Angiosperms) and non-flowering plants.

What are the two main classifications of animals?

Vertebrates (with backbone) and invertebrates (without backbone).

What characteristics are used for classification?

Body structure, type of cell, mode of nutrition, movement, and reproduction.

What is the role of decomposers in the ecosystem?

Organisms like fungi that break down dead or living matter, cleaning the environment.

What is the difference between angiosperms and non-flowering plants?

Angiosperms have flowers and fruits, while non-flowering plants do not.

What are examples of vertebrates?

Fish, amphibians, reptiles, birds, and mammals.

What are examples of invertebrates?

Insects, worms, and molluscs.

What is the importance of classification?

It organizes living things, allows for comparison, and helps predict characteristics.
