1. ANIMAL CELLS

2. LESSON OBJECTIVES
Label and identify the major structures that make up a typical animal cell.
Describe what these structures do.
Name and describe how 2 specialised animal cells are adapted for their job.

7. LESSON OBJECTIVES
Label and identify the major structures that make up a typical animal cell.
Describe what these structures do.
Name and describe how 2 specialised animal cells are adapted for their job.

8. ORGANELLES cell membrane nucleus
controls what enters and leaves the cell
contains the DNA and so controls the cell
cytoplasm
DNA
metabolic (chemical) reactions occur here
contains the coded instructions to make proteins

9. Cell organelles
Nucleus: The “brains” of the cell, the nucleus directs cell activities and contains genes.
A cell membrane controls what enters and leaves the cell.
Cytoplasm, where most of the chemical reactions take place.

11. Mitochondria Found in the cytoplasm.
Carry out aerobic respiration to release energy.

12. Ribosomes

13. MINI PLENARY Question 4 What is the function of the cell membrane?
Supports and protects the cell
Controls the cell
Controls what enters and leaves the cell
Metabolic reactions occur here

14. What is the function of the nucleus?
MINI PLENARY Question 5
What is the function of the nucleus?
Supports and protects the cell
Controls the cell
Controls what enters and leaves the cell
Metabolic reactions occur here

15. LESSON OBJECTIVES
Label and identify the major structures that make up a typical animal cell.
Describe what these structures do.
Name and describe how 2 specialised animal cells are adapted for their job.

16. SEX CELLS: GAMETES Nucleus containing 23 chromosomes AN EGG CELL
A SPERM CELL
Nucleus containing 23 chromosomes

17. They are UNSPECIALISED.
The Zygote
Fertilised Egg cell.
Division forms a ball of
genetically Identical
cells.
The first 8 cells are
Embryonic stem cells.
They are UNSPECIALISED.

18. How many different specialised cells can you name, in animals.
Sex cells- Eggs and sperm
Neurones/Nerves- brain.
Muscle cells
Blood cells, white and red

19. RED BLOOD CELL
SPERM CELL
NERVE CELL
MUSCLE CELL
WHITE BLOOD CELL

20. Sperm cell Designed to Fertilise eggs. Found in the Testes
Head contains enzymes & nucleus
Designed to Fertilise eggs.
Found in the Testes
Tail
A sperm is small and has a long tail that provides movement so it can swim and find an egg cell.
The head contains enzymes which allow it to digest into an egg cell and join with it.

21. Red blood cells transport oxygen
cytoplasm contains no nucleus
cell surface membrane
allows more room for haemoglobin
cytoplasm contains haemoglobin
haemoglobin is a protein which carries the oxygen molecules
bi-concave disc shape
increases surface area over which absorption of oxygen can occur

22. Muscle cells contract and enable movement of the body
Muscle cells have many nuclei
nucleus
cell surface membrane
protein strands
The strands of protein slide over each other making the muscle cell (fibre) shorter and causing the muscle to contract

23. Ciliated EPITHELIAL cells move bacteria and dust away from the lungs
Cilia are small extensions of the cell. They beat rhythmically to sweep mucus, which has trapped bacteria and dust, away from the lungs
