The products of photosynthesis in the leaves flow to the roots through vascular tissue called:

Question

1. Phloem

2. Xylem

3. Meristem

D. Angiosperm

Which one? I don't even understand the question -- can someone explain

Answer 1

1. Phloem

The question is asking for the name of a vascular tissue.

That eliminates answers 3 and D.

The question is asking for the vascular tissue in which the flow is from the leaves toward the roots.  That describes only 1 Phloem.

My biology teacher used to say "food flows through the phloem."

Then he'd go on to say that xylem carries water and minerals, but that doesn't carry the same memorable flavor.  LOL.

Answer 2

it's the phloem. this is the vascular tissue which carries synthesised substances or sugars from the leaves of a plant to where required eg, roots or stem

Answer 3

1. Phloem.

From source to sink. Sucrose is produced as a result of photosynthesis in the leaves (the source) and transported around the plant in the phloem to where it is needed (the sinks).
