Question 1

What are the 5 characteristics that multicellular land plants and green algae share?

Answer 1

Cell wall composed of cellulose, cell division including cell plate, same type of chlorophyll, similar genes for rRNA, food stored as starch, same type of enzymes in cellular vesicles

Question 2

What are the 5 adaptations?

Answer 2

cuticle, stomata, vascular tissues, seeds, reproductive strategies

Question 3

What is cuticle?

Answer 3

a fatty or waxy coating that helps prevent water evaporation from plant tissues

Question 4

What is stomata?

Answer 4

openings in the outer cell layer of leaves that enable gas exchange

Question 5

What is vascular tissues?

Answer 5

specialized transport tissues that enable faster movement of substances than by osmosis or diffusion

Question 6

What are reproductive strategies?

Answer 6

some land plants can reproduce with spores that have water protective covering

Question 7

What are spores?

Answer 7

Spores are haploid cells that can produce an organism without reproduction

Question 8

What do seeds do?

Answer 8

embryo, nutrients for the embryo, protective coat

Question 9

What is dominant in vascular and non vascular plants?

Answer 9

In nonvascular plants, gametophyte is dominant. In vascular plants, sporophyte is dominant
