Answer:
Xylem cells have no cytoplasm or end walls, meaning they form a tube through which water can pass freely to allow water transport. Lignin strengthens the cell walls, helping to support the plant.
In eukaryotic cells, the DNA that codes for the cell's proteins is stored in a membrane-bounded organelle called the nucleus.
<h3>What is the nucleus?</h3>
The cell nucleus is an organelle delimited by a membrane where the cellular genetic material organized in DNA molecules together with proteins such as histones is stored. Its function is to keep this genetic material protected and control the expression of DNA, as in the transcription of proteins.
Therefore, we can confirm that In eukaryotic cells, the DNA that codes for the cell's proteins is stored in a membrane-bounded organelle called the nucleus.

Diabetes is my final answer
Answer: feed-back
When the product of a metabolic pathway accumulates, it may be able to slow down or turn off the pathway by inhibiting the activity of an enzyme that catalyzes an early step in the pathway. This is referred to as feed-back inhibition.
Explanation:
Feed-back inhibition is said to occur when the final product of a biochemical pathway signal the inactivation of the starting materials of the pathway.
For example: when pyruvate signal the inactivation of phosphofructokinase, the glycolytic pathway gets turned off.
