Explain how energy from the sun converts water and carbondioxide into food for plant

1 answer:

8 0

Photons of sunlight enter the plant through the leaves and the plant uses this energy in the mesophyll cells (middle cells), more specifically in the chloroplasts, to conduct photosynthesis. The plant transports water and sugars to the plant via the xylem and phloem tubes which allows the plant to grow and thrive. Carbon dioxide is a product made by the cell which is used during glycolysis to make glucose, or sugar, which is food for the plant. The plant also produces oxygen during the process of photosynthesis which diffuses out of the plant into the atmosphere. Water is used in the process as a reactant for most of the reactions that take place. It’s there to help reactions go along and have the correct products.

Some materials can move across the cell membrane against a concentration gradient by

Anastasy [175]

Answer:

Molecules which move against the concentration gradient across the cell membrane employ the mechanism of active transportation.

Explanation:

Normally, permitted molecules moves across the cell membrane of the cell by the process of diffusion and osmosis. This is used when molecules move from hypertonic region to hypotonic region (if ions) and hypotonic to hypertonic (if water). This is a passive transportation which do not require the expense of energy from the cell.

In contrast, when molecules move in or out of the cell against their concentration gradient, that is ions moving from hypotonic region to hypertonic region, they implore the expense of energy in form of adenosine triphosphate (ATP), and the involvement of the membrane carrier proteins. This is called active transport.

When a person drinks alcohol, the rate of urination increases. This suggest that antidiuretic hormone (ADH) may be affected by a

Ulleksa [173]

Answer:

d. alcohol inhibits the release of ADH

Explanation:

Alcohol play an opposite role in water reabsorption. ADH is made in supraoptic nuclues of hypothalamus and transfers fby neuron to posterior pituatry where it gets stored and secreted. Alcohol stops the release of ADH from posterior pituatry which decreases the serum level of ADH. As the ADH level lowers it wont be able to reabsorb water from the distal/collecting tubules of kidneys leading to increase in urine volume and urination.
