Cell Parts
Make sure you know the functions of the following:
Which ones are in animal cells, plants cells or both?
Cell Wall Chloroplast
Nucleus
Cytoplasm
Vacuole
Cell Membrane

Unicellular Organisms
Consist of 1 cell! That cell has to do all the jobs to keep
the organism alive
Euglena
Paramecium
8
Unicellular Organisms
Insert the “Unicellular Organisms” diagram into your notes.
On the diagrams, label as appropriate: Nucleus Cell wall Chloroplast Cilia Contractile vacuole
9
Multicellular Organisms
Made of many different types of cell
Each type of cell carries out a different function.
10
Multicellular Organisms
1. Insert the “Animal Tissues” diagram into your notes.
2. Name each of the tissues and the types of cells present.
3. Below each diagram describe the function of each cell type.
4. Describe how red blood cells and ciliated columnar cells are suited to their function.

Multicellular Organisms
1. Insert the “Plant Tissues” diagram into your notes.
2. Name each of the tissues and the types of cells present.
3. Below each diagram describe the function of each cell type.
4. Describe how palisade mesophyll cells and root hair cells are suited to their function.
