1. Making new cells - mitosis
Animal cells
Plant cells
Specialised cells
A root hair cell has a large surface area to absorb more water from the soil by osmosis.
Part of cell
function
Cytoplasm
A jelly-like material that contains dissolved nutrients and salts and structures called organelles. It is where many of the chemical reactions happen.
Nucleus
Contains genetic material, including DNA, which controls the cell’s activities.
Cell membrane
Its structure is permeable to some substances but not to others. It therefore controls the movement of substances in and out of the cell.
Mitochondria
Organelles that contain the enzymes for respiration, and where most energy is released in respiration.
Ribosomes
Tiny structures where protein synthesis occurs
Making new cells - mitosis
Plant cells also have additional structures:
Part of cell
Function
Chloroplast
Organelles that contains the green pigment, chlorophyll, which absorbs light energy for photosynthesis. Contains the enzymes needed for photosynthesis.
Cell wall
Made from cellulose fibres and strengthens the cell and supports the plant.
Permanent vacuole
Filled with cell sap to help keep the cell turgid.
