Answer:
The correct answer is - zero or 0%.
Explanation:
The fertilization in flowering plants takes place by fusing the pollen of one plant or flower with the ovum of another plant or flower of the same species normally and form a zygote. The zygote gets an equal amount of genetic material from both parent plants by the process f exchange of the genetic material.
The ovum or the egg cell of the plant is considered as the mother and the mother is responsible for the chloroplast And mitochondria of the progeny so in this case, the ovum and egg cell comes from the only plant Q thus, the percentage of chloroplast genes provided via Plant R is 0%.
Photorespiration limits casualty products of light reactions
that build up in the absence of the Calvin cycle. In many plants,
photorespiration is a problem because on a hot, dry day it can drain as much as
50% of the carbon fixed by the Calvin cycle. The closing of stomata reduces access to CO2
and causes O2 to build up. These conditions favor a seemingly not useful process
called photorespiration. In most plants
(C3 plants), initial fixation of CO2, via rubisco, forms a three-carbon
compound. In photorespiration, rubisco
adds O2 instead of CO2 in the Calvin cycle. Photorespiration eats up O2 and
organic fuel and releases CO2 without producing ATP or sugar. Photorespiration
can evolve relic because rubisco first evolved at a time when the atmosphere
had far less O2 and more CO2.
The answer would be C. H2O is polar while O2 is nonpolar.
Glucose gets into the cells through a process called facilitated diffusion. This is a transport mechanism in which carrier proteins shuttle molecules across the cell membrane without using the cell's energy supplies and so it is called passive transport. The carrier proteins bind to glucose, which causes them to change shape and translocate the glucose from outside of the cell membrane and into the cell.
(a) glucose is important because it is the primary source of energy for the cell.
(b) Glucose is 6 - carbon monomer of starch. It is a sugar.
(c) Glucose is broken down to pyruvate through the process of glycolysis.
