**[Cell membrane]** it forms the boundary between the cell contents and the surroundings. It can control the movement of substances into and out of the cell. **[Cytoplasm]** all the activities of this cell take place here. It contains cell organelles but as mitochondria and ribosomes, and food reserves such as glycogen, starch oil droplet. It may look granular. **[Mitochondrion]** The mitochondrion is the organelle in which respiration takes place, releasing energy for cell activities. Active cells such as liver cells contain large numbers of mitochondria. The structure of the microconidia is not easy to see as they are only just visible when cells are viewed using a light microscope. **Cell wall** the cell wall is a nonliving layer outside the cell membrane of a plant cell. It allows liquids and dissolved substances to pass freely through it. The cell wall gives the cell shape and support. Cell walls are not present in animal cells. **Vacuole** A mature plant cell has a large central vacuole filled with cell sap, which is a dilute solution of salts and sugars. It may also contain pigments. If vacuoles are present in animal cells they are small and not permanent. **Chloroplast** the chloroplast is the organelle containing the green pigment chlorophyll, found in the cytoplasm of plants cells. Chloroplasts are present in large numbers in cells such as the palisade cells in a leaf, where photosynthesis takes place.
