What are the two outer layers of a cell? what are they like?
Cell wall= rigid
cell membrane= semi-permeable

Cytoplasm and a cell membrane
what is a chromosone?
DNA is packed into these structures in the nucleus
what is a Vacuole?
Organelle that stores materials such as water salt and carbohydrates
what Does mitochondria do
Converts the chemical energy found in food into stuff that the cell is more convenient to use
Where is the DNA in a cell
In the nucleus
what Does semi permeable mean
Some materials can pass through but not others, like the cell membrane
