MRS GREN (incomplete)
MRS GREN stands for Movement, Respiration, Sensitivity, Growth, Reproductiin , Excretion, and Nutrients.
They are all Life Processes.
Movement - A change of position needed to respond to the surroundings.
Respiration - The process of releasing energy in cells from food or stored chemicals in cells
Excretion - The removal of waste products from the organism
Nutrition - Taking in energy, feeding
Plant and Animal Cells
All cells, except for Red Blood cells, have a nucleus. All cells have cytoplasm, and most have a cell membrane. Most plant cells have chloroplasts, but some - like onion cells - that are undergound, don't. They also have a cell wall.They have a vacuole, and a vacuole membrane.
Nucleus - It's like the brain of the cell, it controls what the cell does and how it moves. Where it can be found: Plant and animal cells.
Cytoplasm - Cytoplasm helps the organelles within a cell move freely and safely around. Where it can be found: Plant and animal cells
Cell membrane - It controls what goes in and out of the cell. Where it can be found: Plant and animal cells
Chloroplasts - an organelle where photosynthesis takes place. Where it can be found: Plant cells.
Vacuole (permanent central vacuole) - Controls the size of the cell and contains sap. Where it can be found: Plant cells
Cell wall - Protects the cell. Where it can be found: Plant cells.
