Which letter shows telophase and cytokenesis?
F
What is interphase?
The period of a cell's life when it carries out its normal metabolic activities and grows.
What happens during interphase?
The DNA-containing material is in the form of chromatin, and the nuclear envelope and one or more nucleoli are intact and visible.
What happens during early prophase?
The chromatin coils and condenses, forming bar-like chromosomes. As the chromosomes appear, the nucleoli disappear, and the two centrosomes separate from one another. Microtubles lengthen and propel the centrosomes toward opposite poles of the cell. Asters extend from the centrosome matrix.
What happens during late prophase?
The nuclear envelope breaks up, allowing the spindle to interact with the chromosomes. Microtubules draw the chromosomes to the center of the cell.
What happens during metaphase?
The two centromeres are at opposite poles of the cell. The chromosomes align at the midline of the cell.
What happens during anaphase?
The centromeres split, and each chromatid becomes its own chromosome. The microtubules pull each chromosome toward a pole as the poles are pushed apart.
What happens during telophase?
The identical sets of chromosomes at the opposite poles of the cell begin to uncoil and resume their threadlike chromatin form. A new nuclear envelope forms around each chromatin mass, nucleoli reappear within the nuclei, and the spindle breaks down and disappears.
What happens during cytokenesis?
A contractile ring of actin microfilaments forms a cleavage furrow around the cell and pinches it apart.

What is the function of the basement membrane of epithelia?
To provide support
What is the function of the basal lamina?
