I hope you enjoy this summarized PP slides on Cells (Parts of a cell and their functions)

1. CELLS: The Basic Unit of Life

2. Lesson objectives:
→ Identify the differences between the plant and animal cell
→ Identifying the various organelles found in the plant and animal cell
→ Know the function of each organelle within the cells

3. Function of Organelles in the cell:

4. Organelles found in the cell:
Functions
1. Cell Wall
 Gives the cell shape and support
 Protects the organelles within the cell
 Only found in plant cells

5. 2. Cell membrane
 Found in both plant and animal cells
 It is the thin flexible barrier around the cell that regulates transport by,
 Controlling the substances moving in and out the cell through diffusion and osmosis
 Protects the cell

6. 3. Cytoplasm
 A jelly like structure that provides mechanical support to the cell.
 Site for activities such as metabolism, protein synthesis and cellular respiration
 Acts a storage area for small carbohydrate, lipid and protein molecules.
 Transport of organelles around the cell.

7. 4. Nucleus
 Responsible for carrying hereditary characteristics through genetic material
 Control cell activities such as cell division (reproduction), protein synthesis (contains
RNA) and metabolism for e.g. producing insulin
 Facilitate DNA replication and control gene expression

8. 5. Mitochondria
 Supplies the cell with energy by producing ATP (Adenosine Triphosphate)
 Through the process of Cellular respiration

9. 6. Chloroplast
 Contains a green pigment called chlorophyll allowing for the absorption of light
energy converting it to chemical energy
 Site for the process of Photosynthesis, light energy

10. 7. Ribosome
 Contains RNA and protein
 Site for protein synthesis
 Found in cytoplasm and the endoplasmic reticulum

11. 8. Plastid
 Plastids are found only in plant cells. There are three types of plastids:
• Chloroplasts- contain chlorophyll and their function is to produce food by
photosynthesis
• Chromoplasts- give colour to fruits and flowers
• Leucoplasts- are used mainly for starch storage

12. Differences between the plant and animal cells

13. End of lesson:
→ Prepare for next lesson – structure of each organelle (cell wall, cell membrane etc)
