What is the function of a nucleus
Contains genetic material, including DNA, which controls the cells activities
What is the function of the cytoplasm
A jelly like material where many of the chemical reactions take place
What is the function of a cell membrane
It has a structure that is permeable to some substances but not others, controlling the movement of substances in and out of the cell
What is the function of a cell wall and what is made from
Made from cellulose fibres and strengthens the cell and supports the plant giving it a solid structure
What is the function of mitochondria
Organelles that contain the enzymes for respiration, and where most energy is released in respiration (the site of respiration)
What is the function of chloroplast
Organelles that contain green pigment, chlorophyll, which absorbs light energy for photosynthesis. Contains the enzymes needed for photosynthesis
What is the function of a ribosome
A tiny organelle where protein synthesis occurs
What is the function of a vacuole
It is filled with cell sap to help keep the cell turgid

Explain the importance of cell differentiation in the development of specialized cells
They are important as they are able to perform specialized functions in the body
What are the advantages and disadvantages of using stem cells in medicine
Disadvantages - Cultured stem cells could be contaminated with viruses that would be transferred to the patinent - Difficult to find donors and to carry out pocedures Advantages - They can be very effective and can be used to grow back organs
