All species of fungi, plants and animals are formed from eukaryotic cells. The Eukaryote have a true nucleus; their DNA is confined to a definite area within the cell enclosed by a Nuclear envelope. Prokaryotes evolved before eukaryotic cells and their cells do not have a true nucleus. Prokaryote DNA is not enclosed by a membrane.

ORGANELLE STRUCTURE FUNCTION PLANT OR ANIMAL
Nucleus Within the cell membrane Site of the nuclear material-the DNA both
Nucleolus Inside nucleus Manufacture of ribosomes both
Mitochondrion Numerous in cytoplasm. Up to 1000 per cell. Aerobic respiration both
Rough endoplasmic reticulum Continuous throughout cytoplasm Isolation and transport of newly synthesised proteins Both both Smooth endoplasmic reticulum Usually small patches in cytoplasm Synthesise of some lipids and steroids both
Ribosome Free in cytoplasm or attached to rough ER Site of protein synthesis both
Golgi body Free in cytoplasm Modification and synthesis of chemical both
Lysosome Free in cytoplasm Digestion of unwanted material both
Chloroplast Cytoplasm or some plant cells, e.g.mesophyll Site of photosynthesis plant
Vacuole Usually large, single fluid -filled space in plant;smaller and more numerous in animals Storage of salts, sugars and pigments; creates turgor pressure by interaction with the cell wall plant
Plasma membrane Encloses the cytoplasm of all cells Exchange and transport of materials into and out of the cell both
Cell wall Surrounds all plant and fungal…
