Biology

vagabundo [1.1K]3 years ago
7 0

Cell division allows for the growing of new cells. With a unicellular organism, cell division would be the cell's way of reproducing or multiplying, in other words, surviving. Within a multicellular organism, cell division is the organism's way of replacing old, damaged, or dead cells. Within multicellular organisms, cell division also aids in growth.

Answer:

a Anaphase I

b Metaphase I

c Telophase I

d Anaphase II

e Prophase I

f Telophase II

Explanation:

Prophase I begins after the DNA has been duplicated, as shown in picture e. The chromosomes are condensed, and also visible, which is apparent in picture e.

The next stage is called Metaphase I, in which the pairs of homologous chromosomes align at The the centre of the cell and the spindle fibres attach, as shown in picture b.

The pairs of chromosomes are pulled apart to opposite poles of the cell by the spindle fibres., as shown in picture a. This stage is called Anaphase I.

Then, a process called Telophase I occurs, when the cell divides into two daughter cells. One of these cells is shown in picture c.

Picture d shows the stage Anaphase II, where the spindle has attached and the chromatids are pulled to the opposite poles of the cell.

The final picture left is picture f, which shows the daughter cell at the end of meiosis II, where the nuclear envelope is reforming, as in telophase II.
