Revise GCSE, label and desribe a typical cell function.
Animal: Have nucleus, cell membrane, and cytoplasm. The nucleus has the nuclear membrance & envelope, and it contains DNA and chromatin. There is the cell surface membrane around the outside. In the cytoplasm there are enyzmes to catalyse reactions, and ribosomes to make protiens. The pores around the nucleus allow connection to the rest of the cell, and mRNA to pass through. Mitochondria also exist in animal cells, which aid in respiration (aerobic).
Plant: Has a cell membrance, vacuole, cytoplasm, mitochondria (or mitochondrion, singularly.) Chloroplasts, a nucleus, and a cell wall for stability.
