Why are most of the stomata on the bottom of the leaf

Biology
1 answer:
larisa86 [58]3 years ago
3 0

Answer: Stomata plays very crucial roles in plants. During photosynthesis, gas exchange takes place via the stomata. Water also evaporates from plants through the stomata. In plants, most of the stomata are usually on the bottom of the leaf IN ORDER TO PREVENT EXCESSIVE LOSS OF WATER.

During the day, the sunlight falls on the leaf directly and draws water from the plants. Locating the stomata at the underside of the leave reduces the amount of water that can be lost through excessive evaporation. Also, locating the stomata on the underside of leaves prevent  the leaves from taking in too much water during rainfall.

Answer:

According to the warning signs that exist in radiology clinics, a pregnant woman should consult her physician before undergoing an x-ray study because x-rays are a form of ionizing radiation that can affect the development of a gestational baby.

Explanation:

<em>Signs/notices in radiology clinics indicate that women who are pregnant or suspect they may be pregnant should consult their doctor before undergoing a radiological examination. Why should they do it?</em>

X-rays are a type of electromagnetic radiation -ionizing- capable of passing through the body, used to obtain images of the interior of an organism by capturing these rays on photographic film.

It is well known that X-ray radiation can have mutagenic effects on living organisms, according to the amount of radiation and the time to which it has been exposed. In the pregnant woman, who has a fetus developing inside her, special attention must be taken due to the harmful effects that ionizing radiation can have on its development. This is the main reason why a pregnant woman should consult her doctor before undergoing a radiological study.
