1.2 Ultrastructure of cells


 
Animal Cell
Here we are going to draw and label an animal cell with all relevant cell organelles.


 
Plant Cells
A plant cell differs in three important aspects to an animal cell. We label a plant cell and then make a comparison table to outline the differences between plant and animal cells.


 
Function of cell organelles
Different cell organelles are responsible for different tasks. Here we have alook at these tasks.


 
Prokaryotic Cells
Prokaryotes are the simplest types of cells. They do not have a nucleus, are smaller than eukaryotes and do not have membrane-bound organelles.

Different types of cell organelles
Cell organelles can be categorized by the number of membranes that they have.


 
Plant cells
Plant cells differ from animal cells in that they have a cell wall, a large central vacuole and (possibly) chloroplasts.


 
Drawing animal cells
Here we are drawing an animal cell with all of the cell organelles.


 
Drawing plant cells
Here we are drawing a plant cell with all of the cell organelles.


 
Cell organelle function
Different cell organelles perform different functions. This video explains what they do.


 
Identifying structures
Sometimes the cells look quite different under a microscope. Here we are identifying the different structures.
