Where does gas exchange occur in a plant?

Biology
1 answer:
Finger [1]4 years ago
6 0

Gas exchange in a plant occurs through the tiny pores called stomata found in the leaves of plants.

Gas exchange occurs during photosynthesis. Carbon dioxide is taken from the atmosphere through the stomata and oxygen is released as a waste product.  Gas exchange is essential for the  plant's survival.

Normally stomata open when the light strikes the leaf in the morning and close during the night. Opening and closing of stomata is guided by two guard cells which are found on each side of the stomata.  When the guard cells become turgid,  they bend into a crescent shape allowing the stomata to open. When they lose turgor pressure, they become flaccid and return to their original shape and the stomata close.

Answer: Option (4)

Explanation: Methane (CH4) is one of the green house gas which is about 0.00017% by volume at present.

                   With the increasing number of factories and the industries, a noticeable amount of methane has been released to the atmosphere so far, and they have the ability to exist in the atmosphere for about 10-12 years. It can also be reduced when undergoes chemical reaction in the atmosphere.

Hence, the correct option here is (4)

11Alexandr11 [23.1K]

Answer:

Explanation:

Anvisha [2.4K]

Answer:

In bees, The males (drones)  genes are 100% the queen's genes (develops from the unfertilized egg), this is haplodiploid, but the females (workers and queens) have 100% of the father's gene but 50% of the mothers (queen)

Explanation:

In relatedness or diploid, both parents share and pass on a complete set of genes to the offsprings, but for haplodiploidy, all the genes of one parent are passed to the offspring excluding the other parent as in the case of drones to queen bees.

Mrrafil [7]

Answer:

Explanation:

The production of ATPs for skeletal muscle contraction  depends on the conditions that the muscles are exposed to.

In presence of abundant oxygen, to the cells  Aerobic respiration-cellular respiration is the most ideal. 32 ATPs and 4 C02 are produced as by-products during the process as by products majorly two C02 from each  of the 2 acetyl Co A that enters the  kerb's cycle.

Likewise direct phosphoryaltion of ADP to ATP gives 32.0 kj/mol of heat liberated but no C02 was produced. This takes place during chemiosmosis. with 28ATPs produced.

In absence of oxygen, anaerobic respiration of skeletal muscles produced ATPs  from  glycolysis, heat and  2C<u>02 as products, but not as by-product</u>.Through alcoholic fermentation pathway.

Therefore ,the correct answer is Aerobic respiration, because it gives out C02 which is a by-product, released out of the body as waste from the lungs,and not use up  in  the body.
