ORGANELLES
|
Cell structures specialised with a specific function
|
CELLS
|
Basic functional and structural units in a living organism
|
TISSUES

|
ORGANS
|
Composed of different tissues carrying out a particular function
|
SYSTEMS

CELL STRUCTURE:
CELL STRUCTURE
|
DESCRIPTION
|
NUCLEUS
|
Membrane-bound organelle that contains genetic material
|
CYTOPLASM
|
Material that fills cell to facilitate chemical reactions and hold organelles in place
|
CELL MEMBRANE
|
Phospholipid bilayer that controls the movement of substances into and out of cell
|
CELL WALL
|
External to cell membrane that protects and maintains the shape of cell (prevents cell from bursting)
