All of the following is a root function, except

• water absorption
• food storage
• plant anchoring
• food production

What part of a plant transports water and nutrients from the root to the plant's stem and leaves?

• root hairs
• phloem
• xylem
• cuticle

Gases pass in and out of a leaf through the

• phloem
• xylem
• cuticle

Germination will not happen unless a seed

• is dispersed far from the plant that produced it
• absorbs water
• uses its stored food
• grows stamens and a pistil

What happens in the phloem?

• water moves up from the roots
• food moves down from the leaves
• food moves up from the roots
• water moves down to the roots

The leaf's cuticle

• stores water
• reduces evaporation
• transports water in the leaf
• absorbs water for the leaf
