Animal Cells
To know how to draw and label animal cells

3. Cells A cell is the basic building block for both animals and plants
Specialised cells
e.g. gametes
Cells
A cell is the basic building block for both animals and plants
Cells are extremely small (we need a microscope to see them)
Animal cells have some basic properties (although this is a basic generalisation - we can get extremely specialised cells)
You need to learn the parts which make up our animal cell…
Animal cells - stained

4. Animal Cell Cytoplasm Animal cells contain: - Cell membrane Cytoplasm
Nucleus

Cell membrane

5. Functions
You must also know the functions of the parts which make up the animal cell
Part
Function
Nucleus
Controls what happens in the cell (but it is not a ‘brain’)!
Cell Membrane
Controls what substances can enter and exit the cell
Cytoplasm
Where chemical reactions take place (jelly-like substance)
The nucleus is like the party organiser
The cell membrane is a bit like a fence around the cell, with some bouncers at the gates. These bouncers are selectively permeable meaning they let some materials in and out, and stop other materials from entering or leaving
The cytoplasm is the dance floor, where everyone interacts

6. Cell membrane (selectively permeable)
Task
Your task is to draw out a standard animal cell, which needs to take up a whole page in your book (it needs to be neat, labelled, and colourful)
Then, on the other page, you need to draw a cartoon representation of an animal cell (you can do the party representation I did, or use your own idea)

7. Summary
Remember, a ‘standard’ animal cell has a nucleus, cell membrane, and cytoplasm
The nucleus controls what takes place within the cell
The cytoplasm is where the chemical reactions occur
The cell membrane is selectively permeable, allowing some materials in and out, whilst stopping others
However there are other animal cells which are much more specialised - can you identify any for next lesson?
