Answer:

Cytokinesis

Explanation:

The cleavage furrow is a 'pinching' or invagination in the cell membrane that occurs before the cell cytoplasm splits in two to form two daughter cells.

This occurs towards the end of mitosis, during telophase. This means that cytokinesis will not be able to proceed properly. Cytokinesis is when the cytoplasm divides to form two new cells. Without the cleavage furrow, the cell is not divided in two, and the new daughter cells cannot form. Therefore, cytokinesis cannot proceed properly.

A cell found in the root of the plant would most likely lack what cell structure.
mestny [16]

Answer:

The cells found in the root of the plant normally lacks chloroplasts, as roots do not perform photosynthesis. The main function of chloroplast is photosynthesis.

Explanation:

The plant cell contains nucleus, cell wall, cell membrane, mitochondria, chloroplasts, vacuole, endoplasmic reticulum, ribosomes etc. Chloroplasts contain green pigments which give green color to the plants. The main function of chloroplast is photosynthesis. During photosynthesis, the plants produce glucose and release oxygen by using carbon dioxide from the air, and absorbing water and nutrients from the soil. Using the glucose in the plants and oxygen, mitochondria produce energy.

The root system of the plants absorb water and nutrients from the soil. The absorbed water and nutrients are then transported to various parts of the plant to carry out processes like photosynthesis, maintaining turgor pressure etc. They have different types of cell which perform some specific functions. These cells also contain cell wall, cell membrane and mitochondria. Mitochondria provides energy for the active transport of water and nutrients. But chloroplasts are absent in root cells as they do not perform photosynthesis.

Anna71 [15]

Answer:

1) Not as it were does breathing give your body with essential oxygen, but it too frees the body of squander like carbon dioxide. To urge freedom of carbon dioxide, your blood conveys it to the capillaries encompassing your alveoli. Within the alveoli, the carbon dioxide moves into the lungs, where it takes off the body once you exhale.

2) The stomach is the dome-shaped sheet of muscle and ligament that serves as the most muscle of breath and plays a crucial part within the breathing preparation. Moreover known as the thoracic stomach, it serves as an imperative anatomical point of interest that isolates the thorax, or chest, from the guts. It contracts ceaselessly as you breathe in and out.

3) Discuss at that point voyages down the pharynx and larynx, through the trachea, and into the lungs. Within the lungs, discuss passes through the branching bronchi, coming to the respiratory bronchioles. The respiratory bronchioles open up into the alveolar conduits, alveolar sacs, and alveoli.

4) Gas trade takes put within the millions of alveoli within the lungs and the capillaries that wrap them. As appeared underneath, breathed in oxygen moves from the alveoli to the blood within the capillaries, and carbon dioxide moves from the blood within the capillaries to the discuss within the alveoli.  The dividers of the alveoli share a film with the capillaries. That's how near they are. This lets oxygen and carbon dioxide diffuse, or move openly, between the respiratory framework and the circulatory system. Oxygen particles join to ruddy blood cells, which travel back to the heart.

5) After you have pneumonia, it's conceivable for your lungs to fill with liquid. In case that happens, they won't be able to exchange sufficient oxygen to your blood or get freed of the carbon dioxide in your blood. It's a genuine condition since your organs require oxygen to work.

Tried my best. Hope this helps :)
