Animal Cells- Term

NUCLEUS

1 of 16

Animal Cells- Definition

A nucleus controls all the activities of the cell. it also contains the instructions for making new cells or new organisms.

CYTOPLASM

3 of 16

Animal Cells- Definition

The cytoplasm is a liquid gel in which most the chemical reactions needed for life take place. One of the most important of these is respiration, where oxygen and sugar react to release the energy the cell needs.

MITOCHONDRIA

7 of 16

Animal Cells- Definition

The mitochondria, structures in the cytoplasm where most of the energy is released during respiration.

Plant Cells- Term

CELL WALL

11 of 16

Plant Cells- Definition

A cell wall made of cellulose which strengthens the cell and gives it support.

Plant Cells- Term

CHLOROPLASTS

13 of 16

Plant Cells- Definition

Chloroplasts, found in all green parts of the plant. They are green because they contain chlorophyll which gives the plant its colour. They absorb light energy to make food by the process of photosynthesis.

PERMANENT VACUOLE

15 of 16

Plant Cells- Definition

A permanent vacuole (a space in the cytoplasm filled with cell sap), which is important for keeping the cells rigid to support the plant.
