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.

When a cell is immersed into a salty solution, the osmotic pressure generated by concentration differences of salt, will make the salt come in due to cell self-protection mechanism of the cell and water will come out, eventually the cell can burst .But since the animal cells has a higher concentration of salt and the solution has a lower concentration osmosis will take place and salt will move from higher salt concentration to lower.
