How permeable are cell membranes
Partially Permeable
What does a cell membrane look like
A thin layer of protein and fat around the cell
What is the function of the Cell membrane
It controls what enters and leaves the cell
What does a cell wall look like
A thick layer of cellulose outside the cell membrane
What is the function of the Cell wall
To give the cell protection and support
Which cells contain a cell wall
Plant Cells (also fungi and bacteria cells)
Where do metabolic reactions take place
Cytoplasm

Storing Genetic information
What is inside the nucleus
Chromosomes
What is a chromosome
It is a structure that holds DNA
What is DNA
A molecule with genetic information (genes) controlling the proteins made in the cell
Where is Chlorophyll stored
Inside Chloroplasts
Which type of cell contains chloroplasts
Plant Cells
What parts of a plant have chloroplasts
