gas-filled air spaces.
stems.
specialized reproductivefeatures.
specialized roots.
increased area for photosynthesisin the leaves.

Question 1

The key innovation that allowed for plant survival on land, seenin the first land plants and all others after, but not in thecharophytes, is

Question 1 options:

fruit.

vascular tissue.

the seed.

protection of the embryo.

Question 2

Which dramatic change in the alternation-of-generations lifecycle led to the protection of all phases of the life cycle and theformation of seeds?

Question 2 options:

transition from a dominant gametophyte generation to a dominantsporophyte generation

transition from a dominant sporophyte generation to a dominantgametophyte generation

Question 3

Which structure(s) allow the sporophyte of vascular plants to beprotected against drying out?

Question 3 options:

the waxy covering of leaves, called the cuticle

small openings in the leaves, called stomata

guard cells that surround each stoma

all of these structures protect the dominant sporophyte fromdrying out

Question 4

Why are the bryophytes called nonvascular plants?

because they are specialized for transporting water and organicnutrients
