Key Points

Mitochondrion/a

Aerobic Respiration

Produces ATP  used for energy

Highly folded internal membrane to give large surface are for enzymes- ATP and atpase which can be broken down in to ADP and energy, diphosphate and triphosphate

Chloroplast

Site for photosynthesis

Grana made of stacks of membrane to give large surface area for chlorophyll and other pigments

Nucleus

Contains the DNA of chromosomes which holds the genetic information

It is separated from the cytoplasm by a nuclear envelope with pores for communication between nucleus and cytoplasm.

Nucleolus

Responsible for the production of ribosomes

Dark-staining are in nucleus

Ribosome

Amino acids assembled to make proteins

Situated on rough ER…
