Which image represents cytokinesis in a plant cell?​

Answers

Answer:

D

Explanation:

gl (:

A crucial function of cytokinesis is to divide the cell in half and make sure that one nucleus is placed in each daughter cell. Thus, option D is correct.

What is the importance of cytokinesis in plant cells?

The four steps of cytokinesis are membrane insertion, contraction, and completion. Animal and plant cells experience these stages in different ways.

The assembly and action of an actomyosin-based contractile ring during animal cytokinesis were characterized as occurring at the cell periphery.

In contrast, it was thought that plant cell cytokinesis involved the centrifugal formation of a new cell wall through the fusion of vesicles generated from the Golgi apparatus.

Therefore, The process of cytokinesis begins at the anaphase phase of nuclear division and lasts until telophase.

Arrow 1 represents oxygen and arrow 2 is nitrogen

Arrow 1 represents carbon dioxide and arrow 2 is oxygen

Answers

Answer: Arrow 1 is carbon dioxide, and arrow 2 is oxygen

Explanation: I got it right in a test.

Photosynthesis is the process of preparing food in the presence of sunlight, water, and carbon dioxide. The process is carried out by the plants and certain bacteria and algae.

The correct answer is:

Option D. Arrow 1 represents carbon dioxide and arrow 2 is oxygen

The mechanism of photosynthesis can be explained as:

Photosynthesis is the process in which light energy is converted into chemical energy. The plants use up carbon dioxide and water in the presence of sunlight to yield products.

During photosynthesis, the plants yield oxygen as a by-product and produce a sugar molecule to be used as energy.

Thus, the plants use carbon dioxide and give out oxygen during photosynthesis.
