Answer:
For the photossynthesis there are requirement of cholorplast which is found on the surface of the plant leaves mostly that traps the light and convert light energy to the storage energy or glucose. Leave have larger surface area so the maximum amount of light can be traped for the photosyntheis by the cholorplast present in palisade cells.
Other than this leaves also helps in the gaseous exchange with stomata; small openings, by allowing carbon dioxide and oxygen into the leafe and outof the leave respectively. The veins helps in the transport of the gluscose and nutrition.
Answer;
C. His mother carried at least one allele for that trait
Explanation;
-Men have a single allele of each gene on the X chromosome, inherited from their mother, and a single allele of each gene on the Y chromosome, from their father.
-A sex-linked trait is a trait that is controlled by a gene or an allele located on the sex chromosome.
-X-linked traits are maternally inherited from carrier mothers or from an affected father. Each son born to a carrier mother has a 50% probability of inheriting the X-chromosome carrying the mutant allele.
