The letter D in Figure 1 represents meiosis, while letter A represents mitosis. Meiosis is a reductional cell division.
Mitosis is a type of cell division where a parent cell divides to produce two genetically identical daughter cells (in this case, diploid cells).
Meiosis is a reductional cell division where a parent cell divides twice to produce four daughter cells having half of the genetic material.
Meiosis occurs in germinal cells, while mitosis occurs in somatic (body) cells.

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.
In the purest sense, no you cannot live without water. Your body is made up of an estimated sixty percent water and it is vital for life functions. You can live for approximately three to four days without water. However, when you are asking if you can subsist on anything else, many things that you might choose do in fact contain water. Other drinks, even sodas have water content, as do many fruits and vegetables. It is possible to get enough hydration from sources other than pure water, but not to survive without it entirely.
