Questão	Responda
1.1 Animal and plant cells Nucleus- controls cell activity Cytoplasm- cell reactions take place Cell membrane- movement in and out of cell Mitrochondria- energy released during aerobic respiration Ribosomes- Protein synthesis All in plant and animal cells Plants also have: Cell wall- made of cellulose for support Chloraplast- chlorapyll for photosynthesis Permanant vacuole- contains cell sap	1.2 Bacteria and yeast Bacteria HAVE cell membrane and cell wall to support cytoplasm Bacteria DONT HAVE a nucleus- the information is stored in the cytoplasm Yeast is a SINGLE cell organism they HAVE a nucleus, cytoplasm, cell membrane and cell wall
1.3 Specialised cells Structure of cell is linked to function Many mitrochondria- MUSCLE CELLS Many ribosomes- GLAND CELLS With tail- SPERM CELL Receptor cells- CONE CELL in eye Neutrons- CNS (central nervous system) Plant cell with chloraplast- MESOPHYLL CELL ROOT HAIR CELL- Bigger surface areato absorb more water and mineral ions	1.4 Diffusion The net movement of particles of a gas or solution from an area of high concentration to low concentration The difference between 2 concentration levels is called CONCENTRATION GRADIENT. The larger the difference in concentration makes diffusion happen quicker E.G Oxygen in cells from bloodstream as cells respire
