This document provides an overview of the organization of living things. It discusses that all living things are made up of cells, which make up tissues and organs that work together in systems. The basic systems of living things are nutrition, interaction, and reproduction. Nutrition involves taking in nutrients, interaction involves sensing the environment, and reproduction allows creating new members of the species. Animals are organized with cells forming tissues and organs, while plants also have roots, stems and leaves.

1. Unit 1
•The organisation
of living things

2. Table of contents
• What do living things do ?
• What are living things made up of ?
• How are animals organised ?
• How are plants organised ?
• What systems do living things have ?

3. What do living things do ?
All living things carry out the basic life processes
of :
Interaction
Nutrition
Reproduction

4. Interaction
• All living things detect information in their
enviroment

5. Nutrition
• All living things take essential nutrients from
their environment

6. Reproduction
• Living things can create new members of their
own species.

7. What are living things made up of ?
• All living things are made up of :
• Cells

8. Animal cell

9. Nucleus
• The nucleus controls everything that happens
inside the cell

10. Membrane
• The membrane surrounds and protects the
cell.
• The nucleus and cytoplasm are found inside
the membrane

11. Organells
• In cytoplasm , we fin special organells that
carry out different life processes.

12. Cytoplasm
• Cytoplasm is a thick clear liquid protected by
the membrane.

13. Plant cell

14. Organelles
• In the cytoplasm of plant cell , there are
special organelles called chloroplasts.

15. Nucleus
• Controls everything that happens inside the
cell.

16. Membrane
• The membrane surrounds and proctects the
cell.

17. Cell wall
• Plants cell have a rigid cell wall around the
membrane.

18. Vacuole
• Plant cells have a vacuole which is like a bag.
• Food and water are stored in the vacuole.

19. Unecellular and multicellular
organisms
• Some living things, such as bacteria or yeast,
are made up of only one cell.
• Other living things , such as trees or butterflies
have many cells

20. How are animals organised ?
• If we put a lot of cells toghether we form
tissue
• If we put a lot of tissue toghether we form
organs
• If we put toghether a ot f organs we form a
system

21. Type of cells:
• Red blood cells
• Nerve cells
• Reproductive cells

22. How are plants organised ?
• If we put a lot of cells toghether we form
tissue
• If we put a lot of tissue toghether we form
organs
• If we put toghether a ot f organs we form a
system

23. The plants have:
• Roots: its the part that absorbs water and
nutrients from the soil
• Stem : its the part that supports the plant and
transports water, minerals and sap.

24. What systems do living things have ?
• Nutrition :we use it to transform the
substances that we need to live and grow
• Interaction: we use it to detect information
about the world and us to react to the
information
• Reproduction: we use it to reproduce by
having children.
