Answer:
a. transcription
Explanation:
<em>Sugar transport in phloem is referred to as pressure flow and it involves the movement of sugar through the phloem vascular tissue from the regions where sugar is synthesized (by photosynthesis) to other parts of the plant's body that require sugar.</em>
The parts of plants where sugar is synthesized (usually the leaf) is known as sugar source while the parts where they are transported is referred to as the source. Sources are usually areas of of high osmotic concentration and high water pressure while sinks are usually areas of low osmotic concentration and low water pressure.
<em>Hence, sugar transport in the phloem can be said to be influenced by the rate of sugar production at the source (rate of photosynthesis), turgor pressure as well as sugar concentration in sinks and sources.</em>
The only option that has no known effect on sugar transport in the phloem is transcription.
The correct option is a.
Answer:
The correct option is d. In C3 plants the conservation of water promotes photorespiration.
Explanation:
Photorespiration is a metabolic pathway that leads to the loss of half the carbon fixed by photosynthesis, it occurs when the rubisco enzyme (which is responsible for carrying out the carbon fixation) of the Calvin cycle acts on oxygen instead of dioxide carbon. Photorespiration occurs in C3 plants, (considered C3, by the three carbon compound) when the CO2 concentration is reduced. The first step of the Calvin cycle is the fixation of carbon dioxide by rubisco, but at low concentrations of CO2, oxygen begins to be set in place. In conditions of moderate temperatures when C3 plants have enough water, the carbon dioxide supply is abundant and photorespiration is not a problem.
Answer:
vacuoles are larger in plant cells than in animal cells
Explanation:
The loss in soil fertility, poor crop production, and hardened soil surface I think
It affects society by taking causing conflicts from farmers and animal rights activists lol not exactly like what I said but you know something similar
