Nucleus

Contains the DNA

Cytoplasm

Contains water and dissolved substances such as sugar and salt

cell membrane

Surrounds cytoplasm. Controls the entry and exit of dissolved substances and separates the cells contents from its surroundings

Ribosome

Site of protein synthesis

Mitochondrea

Site of aerobic respiration

Chloroplast

Contains chlorophyll and the enzymes necessary for the production of glucose by photosynthesis

Vacuole

Contains water necessary to provide turgor pressure and may store ions and molecules

Cellulose cell wall

Provides structural support and protects against damage caused by osmotic intake of water

Rough endoplasmic reticulum

Transport of substances such as proteins within the cytoplasm

Ciliated cells

Movement of mucus in trachea and bronchi

Root hair cell

Absorbtion

Xylem vessel

Conduction and support

Palisade mesophyll cell

Photosynthesis

Nerve cells

Conduction of impulses

Red blood cell

Transport of oxygen

Sperm cell

- Bronchioles
- Grey matter

Cell

Basic structural and functional unit of all organisms
