What is the function of a cell wall? (Plant cell)
Protect the plant cell, maintain its shape and prevents excessive uptake of water.
What does the nucleus contain?
The cell’s genes, enclosed by a nuclear envelope.
Function of RNA?
Protein synthesis
Where is the RNA found in a cell?
In the cytosol and the outside of the ER or Nuclear envelope.
What does the endomembrane system consist of?
Golgi apparatus, endosomes, lysosomes and exosomes.
Function of mitochondria and chloroplasts?
Mitochondria facilitates cellular respiration to generate ATP.
Chloroplasts convert sun energy into sugars.
Similarities between mitochondria/chloroplast and bacteria?
