There are two main types of living cells: animal cells and plant cells. Both contain a nucleus, cytoplasm, cell membrane, mitochondria, and ribosomes. Plant cells also contain a cell wall and chloroplasts. The nucleus controls the cell and contains genetic material. The cytoplasm carries out most chemical processes under enzymatic control. The cell membrane regulates movement of substances into and out of the cell. Mitochondria generate energy through respiration and ribosomes perform protein synthesis. Plant cells have a cell wall that strengthens the cell and chloroplasts that contain chlorophyll to absorb light energy for photosynthesis.

2. Living things are built of:
animal cells plant cells

3. Animal cells contain:
•Nucleus
•cytoplasm
•cell
membrane
•mitochondri
a
•ribosomes

4. Plant cells contain:
• permanent vacuole
• cell wall
• chloroplasts
• nucleus
• cytoplasm
• cell membrane
• mitochondria
• ribosomes

5. Nucleus contains:
controls the
activities of
the cell
genetic
material

6. Cytoplasm
controlled by
enzymes
most chemical
processes
take place here

7. Cell membrane controls:
the movement of
substances of the
cell

8. Mitochondria
energy is released
by respiration
here

9. Ribosomes
protein synthesis
happens here

11. Cell wall
strengthens the cell

12. Chloroplasts contain:
chlorophyll
absorbs light
energy for photosynthesis

13. Permanent vacuole
filled with cell sap to help keep the cell turgid

14. Specialised cells
Leaf cell
Root hair cell
Sperm cell
Red blood cells

15. Diffusion
•Happens when particles are free to
move
•Particles diffuse from an area of high
concentration to an area of low
concentration

16. Osmosis
For osmosis to happen you need:
•two solutions with different concentrations
•a partially permeable membrane to separate them
movement of water from a less concentrated
solution to a more concentrated solution
through a partially permeable membrane.

17. There are two types of cells:
prokaryotic eukaryoticSmaller and
simpler than
eukaryotic

18. Here are two kinds of
prokaryotes:
bacteria archaea

19. There are four kinds of
eukaryotes:
protists fungi plants animals
