Higher Biology Cell Variety

By the end of this lesson: You should be able to: Know that a large variety of cell types exist Know what a unicellular organism is Know what a multicellular organism is Know why multicellular organisms have different types of cell

Characteristics of Living Cells How many can you name? There are 7!

Typical Animal Cell

Typical Plant Cell How many structures can you name? Cell Wall 1 Vacuole Chloroplast 2 5 3 Nucleus Cytoplasm 6 Cell Membrane 4

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

Unicellular Organisms Consist of 1 cell! That cell has to do all the jobs to keep the organism alive Paramecium Euglena

Unicellular Organisms Insert the “Unicellular Organisms” diagram into your notes. On the diagrams, label as appropriate: Nucleus Cell wall Chloroplast Cilia Contractile vacuole

Multicellular Organisms Made of many different types of cell Each type of cell carries out a different function.

Multicellular Organisms Insert the “Animal Tissues” diagram into your notes. Name each of the tissues and the types of cells present. Below each diagram describe the function of each cell type. Describe how red blood cells and ciliated columnar cells are suited to their function.

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