Some starter information Cells are the basic units of life All living organisms contain cells There are many different types of cells Unicellular organisms are made up of just one cell Multicellular organisms are made up of many cells Cells can be stained to see cell structures more clearly
Animal cell structure 1. Cytoplasm 2. Nucleus 3. Cell membrane
Structure and function 1. Cytoplasm Site of biochemical reactions 2. Nucleus Contains genetic information. Control centre of the cell 3. Cell membrane Controls what enters and exits the cell
Cheek epithelial cells: Example of animal cell
Plant cell structure 1. Vacuole 2. Chloroplast 3. Nucleus 4. Cytoplasm 5. Cell membrane 6. Cell wall
Structure and function 1. Vacuole Contains watery cell sap 2. Chloroplast Site of photosynthesis 3. Nucleus Contains genetic information. Control centre of the cell 4. Cytoplasm Site of biochemical reactions 5. Cell membrane Controls what enters and exits the cell 6. Cell wall Boundary round plant cell, maintains cell shape. Freely permeable
