Answer:

Explanation:

Phloem cells are conducting vessels that are found in vascular plant. They are used in the transport of photosynthate produce during photosynthesis from the source of production to other parts of the body.

It consist of sieve elements, which are the conducting vessel that aids transport of sugar round the body. They are very active before maturity at mature they are no longer in use.

Companion cells are used in replacement of sieve element at maturity, they function in metabolism together with the sieve tube Translocation is the transport or movement of sugar round the body.

Girdlings is the removal of the bark of a plant this can inhibit active transport of food.

Non-reducing sugar are monosacharrides such as glucose that are produce and transported round the body of the plant.

P-protein are found in the plants sap usually in large amount in the sieve elements.

Elis [28]

Answer:

The wings of the wasp have high in length due to the presence of dominant gene.

Explanation:

There are two genes present in wasp which indicates the length of the wing. The recessive gene represents short wing while dominant gene represent high length. So the offspring which is produced from the mating of male and female wasp produces offspring having high length of wings. It is because in the offspring only dominant gene expressed while the recessive gene remain hidden.
