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.

MINI PLENARY Question 1 cytoplasm cell wall chloroplast cell membrane
? cytoplasm cell wall chloroplast cell membrane
5
MINI PLENARY Question 2 ? cytoplasm sap vacuole chloroplast nucleus

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

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 cilia nucleus magnification X3000
