• ORGANELLES - THE VARIOUS PARTS OF A CELL THAT PERFORM DIFFERENT FUNCTIONS.

Cells & Organelles:

• Animal cells and plant cells

ANIMAL CELLS: NUCLEUS, CYTOPLASM, CELL MEMBRANE

PLANT CELLS: NUCLEUS, CYTOPLASM, CELL MEMBRANE, CELL WALL, CHLOROPLASTS & VACUOLE

Cells & Organelles:

• NUCLEUS: The brain of the cell, contains DNA.
• CYTOPLASM: The jelly filling of cell, contains water and nutrients.
• CELL MEMBRANE: The soft flexible wall around a cell, controls what goes in and out.
• CELL WALL: A hard outer wall made of cellulose, it for protection and support.
• CHLOROPLASTS:Little green balls in cells that can do photosynthesis.
• VACUOLE: An extra balloon in a cell that can contain nutrients or colours.
