This document discusses biodiversity, the basic characteristics of living things including cells, the structures of animal and plant cells, how animals and plants are organized from cells to tissues to organs and systems, the different types of cells, and the basic life processes of interaction, nutrition, and reproduction. It summarizes that all living things are made of cells that carry out these basic life processes and are organized into hierarchical groups from cells to tissues to organs and systems.

2. What’s biodiversity?
Our planet has millions of species. There are many more species that
we haven’t discovered yet. This is called biodiversity.

3. What are the characteristics of living things?
All living things are made up of cells.
All living things carry out the basic life processes of interaction,
reproduction and nutrition.

Membrane
Organelles
Nucleus Cytoplasm

11. What are the different parts of a plant cell?

16. How are animals organised?
Similar cells join together to form tissues. Different tissues join together to
form organs. Organs work together to form systems.

22. Are all cells the same?
Not all cells are the same. Different cells have different functions.
Red blood cells Nerve cells Reproductive cells

25. How are plants organised?
Plants are organised in a similar way to animals.

Reproduction: the female and
male reproductive systems
Nutrition: the digestive
system, the respiratory
system and the
