Cilia and flagella have similar structures but cilia is
shorter than flagella
typically found close to the nucleus
and contains centrioles which play a part in
microtubule formation.
Centrosomes
small extensions of the surface of some
cells that are involved in absorption of material.
Microvili
2 stages of cell cycle:
Interphase and cell division
the time when the cell undergoes
growth and duplication of DNA.
Interphase
growing in size and producing organelles.
G1(gap)-
DNA of the cell is duplicated.
S phase(synthesis)-
cell continue to grow and prepare for
mitosis.
G2 phase
do not undergo further division.
