Answer 1

Is there a picture or something?

Answer 2

Structure A in Figure 10-4 is the centrioles. role does structure A play in mitosis is: (c) connect to spindle fibers

Centrioles are paired organelles that are found in the cytoplasm of eukaryotic cells. They are composed of microtubules, which are long, thin filaments that form the structural framework of the cell. During interphase, the centrioles are located near the nucleus and are surrounded by a cloud of protein called the centrosome.

As the cell progresses into mitosis, the centrioles replicate and move to opposite poles of the cell. This process is called centrosome separation. The centrosomes act as organizing centers for the spindle fibers, which are microtubules that extend from the centrosomes and attach to the chromosomes. The spindle fibers play a crucial role in separating the chromosomes during mitosis.
