Question 2

Guard cells

Answer 2

Control size of stomata

Question 3

Stomata

Answer 3

Allow for exchange of gases

Question 4

Xylem

Answer 4

In vascular structure; carries water and minerals from roots

Question 5

Phloem

Answer 5

In vascular structure; carries sugars from leaves

Question 6

Root hairs

Answer 6

Tiny projections on the surface of the root that increase water absorption

Question 7

Stigma

Answer 7

Top of female reproductive organ; sticky to trap pollen

Question 8

Anther

Answer 8

part of male reproductive organ; forms and holds pollen

Question 9

Petal

Answer 9

Colorful in order to attract pollinators

Question 10

Sepal

Answer 10

Protects flower bud during development

Question 11

Ovary

Answer 11

Part of female reproductive organ; holds and protects ovules

Question 12

Stem

Answer 12

Takes nutrients to flower

Question 13

Ovule

Answer 13

Contained in ovary; forms seed when fertilized

Question 14

Filament

Answer 14

Part of make reproductive organ; holds anther up so pollinators will reach the pollen

Question 15

Pistil

Answer 15

Female reproductive system; stigma style and ovary

Question 16

Stamen

Answer 16

Male reproductive system; anther and filament

Question 17

Auxins

Answer 17

Phototropism: lengthen plant cells on shaded side so plant bends toward light

Question 18

Gibberellin

Answer 18

Produce increase in size of stems and fruit; rapid growth and ends seed dormancy

Aid in ripening fruit

Question 21

Adaptation: need for water and minerals

Answer 21

Roots for absorption from soil
