Which vascular tissue is involved in the transportation of starch found in fruit pulp? a. xylem b. phloem c. pith

The correct answer will be option B (Phloem).

Explanation:

Phloem is the vascular tissue in plants made of living cells joined end to end which transport organic products from the leaves to other parts of the plants.

In fruits, the food is stored in the form of starch, when starch is needed it is converted to simple sugars and transported via phloem.

In phloem, products enter the phloem by pressure flow mechanism through sieve tube elements and then move along concentration gradient that is from high concentration to low concentration in both upward and downward directions.

Thus, option B is the correct answer.

.

is responsible for the translocation of the nutrients like carbohydrates and amino acids from the leaves to other areas of the plants.

Phloem consists of sieve tubes and companion cells. Sieve tubes are living cells which contain cytoplasm but do not have a nucleus. So its function is supported by a companion cell. The phloem vessel in the vascular bundle will transport sucrose and amino acids away from the leaf. As the vascular bundles are connected with similar structures in the roots, each sieve tube is continuous with those in the roots. Sucrose and amino acids enters the phloem by active transport. Later, it is translocated from the sources to the sinks.

the solute can move "downhill," from regions of higher to lower concentration, relying on the specificity of the protein carrier to pass through the membrane. this process is called passive transport or facilitated diffusion, and does not require energy.
