National 5 Biology Cells Graded A+

National 5 Biology Cells Graded A+ Field of View ️️The circular area you can see when you look down the microscope. Nucleus ️️Controls all of the activities of the cell. Cytoplasm ️️The site of chemical reactions in the cell. Cell membrane ️️Controls what enters and leaves the cell. Made of phospholipids and proteins. Semi permeable. Phospholipid ️️A part of the cell membrane that forms a bilayer. Semi-permeable ️️Only allows some things to pass through. Ribosome ️️Site of protein synthesis. Mitochondria ️️Site of aerobic respiration in the cell. Cell wall ️️protects the cell. Made of cellulose in plants, chitin in fungus and peptidoglycan in bacterial cells. Capsule ️️Only found in bacterial cells - it protects the cell from harm. Vacuole ️️Contains cell sap and helps regulate the water concentration in the cell. Chloroplast ️️Contains chlorophyll and is the site of photosynthesis in the cell. Diffusion ️️The movement of molecules from an area od high concentration to an area of lower concentration down a concentration gradient until the concentrations are equal. Fluid Mosaic ️️A name used to describe the cell membrane because it is able to change its shape and it has different components. Passive transport ️️The movement of molecules without the need for energy. Active transport ️️The movement of molecules against the concentration gradient requiring energy. Osmosis ️️The movement of water from an area of high water concentration to an area of lower water concentration across a selectively permeable membrane. Plasmolysis ️️A plant cell that has lost water by osmosis. Turgid ️️A plant cell that has gained water by osmosis.
