What is the fourth stage of cell division?
Anaphase
6 of 20
What happens in the interphase?
The cell gets ready to replicate by doubling its organelles and genetic material
7 of 20
What are centromeres?
The part of chromosomes where sister chromatids are paired
8 of 20
Describe the telophase
Chromatids arrive at the opposite poles of the cells, membranes begin to form around the new nuclei. The chromosomes disperse and are not visible under a light microscope
9 of 20
What is the first stage of cell division?
Interphase
10 of 20
Describe the metaphase
The spindle fibres align the chromosomes across the cell equator.
11 of 20
Describe cytokinesis in an animal cell
The actin ring around a cell contracts, pinching the cell into two daughter cells with one nucleus each
12 of 20
What becomes visible under a light microscope in the prophase, and why?
Chromatin, because it is condensing.
13 of 20
What is the second stage of cell division?
Prophase
14 of 20
What are the two stages of the interphase, and what happens in them?
The growth phase, where the cell expands as its organelles double; the synthesis phase, where the cell replicates its genetic material.
15 of 20
Describe the prophase
The chromatin becomes visible, the nucleolus disappears, the centrioles move to opposite ends of the cell and spindle fibres extend from them, which form the mitotic spindle
16 of 20
Why do the chromosomes have to line up along the cell equator?
It ensures that at the end of cell division, each new nucleus gets one of each chromosome
17 of 20
Describe the anaphase
Paired chromosomes separate at the centromeres and move to opposite sides of the cell.
18 of 20
Describe cytokinesis in a plant cell.
A cell plate is synthesised between the daughter cells
19 of 20
What is actin?
A type of protein
