1

Two types of vascular tissue and what they transport

-xylem- moves water and nutrients
-Phloem- moves food (glucose and cellulose)

2

Where are the two types of vascular tissue found?

roots, stems, and leaves

3

What are the three functions of a root?

1. supplies water and nutrients
2. anchors the plant
3. stores extra food

4

What are the two types of roots?

Taproot and Fibrous

5

What are the three functions of a stem?

1. support the plant body
2. transport materials
3. some store materials

6

What are the two stem types?

Herbaceous (smaller plants) and woody stems (harder, plants grow taller)

7

What is the function of the leaves?

to make food for the plant through photosynthesis

8

What are the two important products of photosynthesis?

1. glucose (sugar)
2. oxygen

9

What is the equation for photosynthesis?

carbon dioxide+water+sunlight=sugar+oxygen

10

Why is cellular respiration important for plants?

-plant cells use oxygen to produce energy from glucose to survive
Sugar+oxygen------>carbon dioxide+water+energy

11

6 characteristics of all plants

1. photosynthesis
2. cuticle
3. cell walls
4. multicellular
5. producer
6 reproduction

12

chlorophyll

green pigment responsible for absorption of light to provide energy for photosynthesis

13

cell wall

support and protect plant cells

14

producer

make their own food/energy as sugar and stores extra as starch

15

rhizoid

root-like structure in nonvascular seedless plants

16

spore

reproductive cell or multicellular structure that is resistant to stressful environmental conditions and can develop into an adult without fusing into another cell

17

stoma

one of many opening in a leaf or stem that enables gas exchange to occur

18

transpiration

moisture carried through plants and changes to vapor and releases to atmosphere

19

cuticle

waxy coating over a leaf that protects it and prevents water loss

20

sepal

one of the outermost rings modified leaves that protect the flower bud

21

petal

one of the ring or rings of the usually brightly colored leaf-shaped parts of a flower

22

stamen

male reproductive part, produces pollen and consists of an anther at the tip of a filament

23

anther

saclike structures that produce pollen

24

pistil

female reproductive part, produces seeds, consists of ovary, style, and stigma

25

ovary

lower part of a pistil that produces egg in ovules

26

ovule

contains the egg

27

pollen

tiny granules that contain the male gametophyte of seed plants

28

pollination

transfer of pollen from the male reproductive structure to the female structures of seed plants

29

seed coat

coat that surrounds and protects the seed

30

dormant

describes the inactive state of a seed or other plant part when conditions are unfavorable to growth

31

germination

sprouting of a seed

32

tropism

movement of plant in response to its environment

33

limiting factor

something limiting plant growth (sunlight, water, CO2, nutrients, oxygen, temp)

34

sexual reproduction

1. pollination
2. pollen tube grows to ovule
3. fertilization- sperm and egg fuse in ovule
4. ovule develops into a seed
5. ovary around ovule become a fruit
6. seed germinates
