They attach to the centromeres and pull apart new chromosomes to the opposite poles of the cell
Dafna1 [17]3 years ago
6 0

Answer:

Spindle fiber is made up of microtubules that originates from the centriole present at both the poles of the animal cell. Plant cells do not contain centriole but can generate spindles from centrosomes.

During the mitotic cell division, the spindle fiber attach to a specialized structure made up of a protein complex called kinetochore which is present on the centromere of mature chromosome. Then these spindle pull the chromosome toward the pole through their centromere.

These spindle fibers help to separate the chromosomes during nuclear division in mitosis but it also helps in chromosome editing by holding two sister chromatids at their position together.  

The separation of chromosome is necessary so that after cell division both the daughter cell contains genetic material.

Describe how amoebas obtain food?
monitta
Amoeba acquires it food by endocytosis, that is, a small region in the plasma membrane which ultimately forms a intra-cellular membrane-bound vescicle. It engulfs it food using its pseudopodia (temporary protrusion of the surface of the amoeboid cell used for feeding and movement) and forms a vacuole around it. When the food is already trapped inside, it releases a digestive enzyme to digest it. Intake of liquid particles is pinocytosis (cell drinking) while intake of solid particles is phagocytosis (cell eating).

What does the chlorplast do
miss Akunina [59]

Answer:

Explanation:

Chloroplasts are plant cell organelles that convert light energy into relatively stable chemical energy via the photosynthetic process. By doing so, they sustain life on Earth. Chloroplasts also provide diverse metabolic activities for plant cells, including the synthesis of fatty acids, membrane lipids, isoprenoids, tetrapyrroles, starch, and hormones.
