Suppose the phloem of a seed plant is damaged and does not function properly.
Kisachek [45]

Answer:The might likely die.

Explanation:

Phloem and xylem tissues are the major conducting tissues in plant. Xylem conduct ( transports) water and minerals salts from the soil through the roots to all parts of the plant while phloem conducts manufactured food from the leaves to other parts of the plant.

Now, if the phloem of a seed plant is damaged and not functioning well, the manufactured food will not get to other parts of the plant where it is needed or supposed to be stored.

If the plant is no longer getting these nutrients, its growth and development will be affected. It might lead to the death of the plant.

Some plants increase in height due to changes in specialized regions of cells in the tips of their branches. The processes that
Nookie1986 [14]

Answer:

mitosis, cell growth, and differentiation

Explanation:

There are several ways through which plants grow which may include the process of mitosis mainly that involves cell division. The increase in height in plants is attributed to not only cell division but also growth of the newly formed cell.

Mitosis involved division of cell and in cell growth, cells increase their size that ultimately cause growth of plant height. The highly active growth cells are meristem cells that are found at tips of the plants. They are actively dividing zones of plants and with their division and growth plant increases their heights.

Another mechanism, responsible for increase in height is cell differentiation. Differentiation is the process during which cells are specialized to perform specialized function. For example: Xylem are specialized for transport of water. Phloem are specialized for the transport of food. Similarly, some cells are specialized for growth and they are aimed at increasing in size and division that ultimately increase the plant height.

So, mitosis, cell growth, and differentiation are the mechanisms, that increase plant height due to changes in specialized regions of cells in the tips of their branches.

Hope it helps!

Olenka [21]
<span> D.all of the above

</span>

Mitochondria and chloroplasts have striking similarities to bacteria cells. They have their own DNA, which is separate from the DNA found in the nucleus of the cell. And both organelles use their DNA to produce many proteins and enzymes required for their function. A double membrane surrounds both mitochondria and chloroplasts, further evidence that each was ingested by a primitive host. The two organelles also reproduce like bacteria, replicating their own DNA and directing their own division.
