DNA
Why does DNA replicate
To create new cells
Transports materials within the cell.
Vesicle
What is the cell membrane called when it only lets certain materials through.
Semipermeable Membrane
What is the purpose of lipids
Storing energy.
Can An element be broken down into a simpler form by chemical reactions.
No
Consists of A Sugar, a Phosphate and a Nitrogen containing base
Nucleotide
Assists with protein storage in plants
Proteinoplast
The movement of substances through the cell membrane without the input of energy
passive transport

Elaioplast
what carries cellular substances to the cell membrane where they are released to the outside of the cell.
Vesicle
What is the pathway of a newly synthesized protein on its way to being secreted by a cell.
