Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is translocation?
A
the transport of sucrose and amino acids in phloem tissues
B
the transport of sucrose and amino acids in the xylem tissues
C
the transport of water and minerals in the phloem tissues
D
the transport of water and minerals in the xylem tissues
Explanation: 

Detailed explanation-1: -Translocation refers to the transfer of sucrose and other compounds, such as amino acids, throughout a plant. Translocation is the movement of elements within a plant from leaves to other tissue. Plants’ phloem, a type of vascular tissue, is where translocation takes place.

Detailed explanation-2: -Translocation is the transport of sucrose and other compounds such as amino acids around a plant. In general, this occurs between the places where these substances are produced (sources) and the places where they are used or stored (sinks) in early spring: from sources in the root to sinks in the leaves.

Detailed explanation-3: -Translocation is the movement of materials from leaves to other tissues throughout the plant. Plants produce carbohydrates (sugars) in their leaves by photosynthesis, but nonphotosynthetic parts of the plant also require carbohydrates and other organic and nonorganic materials.

Detailed explanation-4: -Translocation refers to transportation of only foods that takes place through phloem after photosynthesis has been carried out in the presence of sunlight and water on the surface of leaves.

Detailed explanation-5: -The cells that make up the phloem are adapted to their function: Sieve tubes-specialised for transport and have no nuclei . Each sieve tube has a perforated end so its cytoplasm connects one cell to the next. Sucrose and amino acids are translocated within the living cytoplasm of the sieve tubes.
