Why is the phloem in a leaf important to the roots of a plant apex?
Nana76 [90]

Answer:

The correct answer will be- phloem transports photsynthetic products to the roots

Explanation:

Phloem is the vascular tissue which specializes in transporting the solute molecules like sugar in the form of sucrose to in the plants.

The phloem connects the photosynthetic organ (Leaves)  to non-photosynthetic organs (stem and roots) of the plants by transporting the photosynthates or sucrose to various parts.

Since the roots also need the energy to perform metabolic functions so need the photosynthates to synthesize the energy molecule. They receive the photosynthates from the phloem.

Thus, phloem transports photosynthetic products to the roots is the correct answer.

How does the movement of materials across the cell membrane relate to an<br> organism’s survival?
ioda

I believe it relates because as we know the cell membrane is permeable meaning that allows oxygen, carbohydrates, food to enter the cell but it doesn't allow the entrance of large molecules that harm the cells.

After all the movement around it, matters because for example without food the mitochondria won't be able to create the energy and then with that energy, the nucleus to use it to complete the main the activities of the cell.

Hopefully this what you meant when you asked the question. Have a nice day/evening
