Animal Cells AND Plant cells:

 BOTH have:

Nucleus- contains genetic material, controls activites in cell

Cytoplasm- chemical processes take place, controlled by enzymes

Cell Membrane- control the movement of substances

Mitochondria- energy is released from respiration

ribosomes- protein synthesis happens here

1 of 3

Plant Cells

Cell Wall- strengthens cell

Chloroplasts- contains chlorphyll which absorbs light for photosynthesis

Permanent Vacuole- filled with cell sap to help keep the cell turgid

both cells have a membrane on the outside, and cytoplasm and a nucleus inside. In the plant only are the cell wall, vacuole, and chloroplast.  (

Specialised Cells

                                                                                       Function      adaption

Leaf Cells- Absorbs light energy for photosynthesis.Packed with chloroplast. Closely packed cells form a continous layer for efficent absoration of sunlight             

Root Hair Cell- Absorbs water and mineral ions from the soil. Long with very thin wall, which gives a large surface area

Sperm Cell- Fertilises female gamete . Head contains genetic information and an  enzyme to help penetrate the egg cell membrane. Middle section packed with mitochondria for energy. Tail moves sperm to egg.

Red Blood Cells- contains hameoglobin to carry oxygen to cells. Thin outer membrance to make oxygen diffuse easily. Shape increases surface area to allow more oxygen to be absorbed. NO NUCEUS.
