For sucrose to be moved from a leaf (source) cell to a root (sink) cell, sucrose is first actively transported into the phloem f
Natali5045456 [20]

Answer:water diffuses into the phloem from the xylem and sucrose moves to the sink

Explanation:Translocation is the movement of ready produced food substances from the site of production to places in the plant where food is needed. such as the roots.the place where food is produced is called the source, the the place where food is used up is called the sink.the leaves are the source in a plant.photsoynthates, which is the plant manufactired food, may move up and down the stem ,majorly to areas of storage and growth.

Surose is the major intermediate product of photosynthesis.it is the form in which sugar is transported.it is conducted by the phloem vessels.this takes place in the long sieve elements that forms the sieve tubes

The high percentage of sucrose in the phloem sap causes water to pass into it from the xylem. This then causes the sap to move from source to sink.

At the sink, sucrose diffuses out of the phloem.it is either stored up or used for growth and repairs

Compare and contrast the two cycles of matter
sertanlavr [38]

Answer:

The two cycles of the matter are the carbon and nitrogen cycle. Both of them are biogeochemical cycles, it means that the chemicals spend a portion of the cycle in living things and non-living things. They are also common in that they both recycle nutrients that are essential to all organisms. 

They are different in the manner that they cycle. Nitrogen is huge, 78% of the air around us is nitrogen. It cannot be used by plants or animals. Once the nitrogen is used by the plant and make its way to the animal, it can be released to decomposition. 

Carbon has no requirement in processing by bacteria prior to plants and animals being able to use. Plants take carbon dioxide and make it sugar, animals eat the sugar. Some of it is released carbon dioxide that we exhale.
