Question

These multicellular plants all have something in common, other than being autotrophic. Unlike moss and liverworts, they can grow to great heights and survive in diverse environments. This is because there is a system for intercellular communication, that moves substances throughout the plant; water and nutrients up from the ground and glucose from photosynthetic tissue to all parts of the plant.

What is responsible for this intercellular interaction in higher plants?

A)
hormones

B)
plasmodesmata

C)
xylem and phloem

D)
meristematic cells

Answer 1

c

Answer 2

Phloem
From Wikipedia, the free encyclopedia
In vascular plants, phloem is the living tissue that carries organic nutrients (known as photosynthate), in particular, sucrose,[1] a sugar, to all parts of the plant where needed. In trees, the phloem is the innermost layer of the bark, hence the name, derived from the Greek word φλόος (phloos) "bark". The phloem is concerned mainly with the transport of soluble organic material made during photosynthesis. This is called translocation.
Xylem is one of the two types of transport tissue in vascular plants (phloem is the other). The word xylem is derived from the Greek word ξύλον (xylon), meaning "wood"; the best-known xylem tissue is wood, though it is found throughout the plant. Its basic function is to transport water, but it also transports some nutrients through the plant.
