Chapter 12 Sections 1-2

Front 1

What 4 characteristics do all plants share?

Back 1

1)making their own food
2)have a cuticle
3)have a cell wall (cellulose)
4)asexual or sexual reproduction(reproduce with spores and sex cells)

Front 2

By what process do plants make their own food? What other name can we call them by?

Back 2

photosynthesis; producers

Front 3

What is a cuticle?

Back 3

an adaptation and a waxy covering on plants(the stem) that protect the plant from dying out.

Front 4

What is a sporophyte?

Back 4

a stage in a plant which produces spores

Front 5

What is a gametophyte?

Back 5

a stage in a plant which it produces gametes(sex cells)

Front 6

What is chlorophyll?

Back 6

a green pigment found in plants(chloroplast) were it absorbs light energy from the sun

Front 7

Explain a plant life cycle

Back 7

1) sporophyte stage
2)gametophyte stage
3)sperm cells firtilize egg cells
4)the firtilized egg becomes a new plant

Front 8

what are the two ways to classify plants?

Back 8

vascular and nonvascular

Front 9

what is vascular and non vascular?

Back 9

vascular: a "tube" in a plants which transports nutrients and water in the plant; they have tissues called vascuar tissues to transport the nutrients
Non-vascular: no "tube" in plant. Uses osmois and diffusion to get is nutrients.

Front 10

why are non-vascular plants smaller than vascular plants?

Back 10

because if the nonvascular plant were larger, than there will be no way for osmosis or diffusion to get to all the cells

Front 11

what are the two divisions of vascular plants?

Back 11

Gymnosperms(non-flowering plants) Angiosperms(flowering plants)

Front 12

where do mosses and liverworts live?

Back 12

on rocks, tree bark, or soil

Front 13

are all seedless plants vascular?why or why not?

Back 13

no b/c there are plants like mosses and liverworts that are nonvascular

Front 14

what do mooses look like?

Back 14

small,green,have rhizoids,lives near ground in groups.

Front 15

Each plant has a slender hairlike threds of cells called rhizoids. what are rhizoids? what do mosses use them for?

Back 15

help hold the plant in place (act like roots);
osmosis and diffusion

Front 16

explain the life cycle of a moss.

Back 16

1)sporophyte stage(releases them into air)
2)spores land on ground and open into a gametophyte
3) sperm cells are carried by water to egg cells.
4)firtilized egg grows into a new plant

Front 17

how are mosses and liverworts important?

Back 17

1)provide fuel when dried and burned
2)leave a rich soil for new plants to grow
3)provide nesting materials for birds

Front 18

is spanish moss really a moss? if not then what is it?

Back 18

no; a lichen (a plant that has fungi and algae that grow together)

Front 19

underground stem of a fern

Back 19

rhizome

Front 20

leaf of a fern

Back 20

frond

Front 21

end of a fern frond

Back 21

fiddlehead

Front 22

where do ferns grow?

Back 22

almost anywhere.

Front 23

explain the life cycle of a fern

Back 23

1)sporophyte stage(realeases spores into air)
2)spores grow into gametophytes
3)gametophyte stage
4)grow into new plants

Front 24

what are the seed parts?

Back 24

1)seed coat
2)stored food(cotyledons)
3)young plant(sporophyte)

Front 25

seed plants without flowers or fruit.

Back 25

gymnosperms

Front 26

what does gymnosperm mean?

Back 26

naked seed

Front 27

what is the life cycle of gymnosperm(pine tree)?

Back 27

1)sporophyte stage
2)male cones open and release pollen
3)pollen sticks to the female cone and firtilizes it
4)female cones open, then it releases seeds

Front 28

importance?

Back 28

christmas trees, building, and paper

Front 29

what are the female parts of a plant?

Back 29

Pistil:sitgma, ovary, ovules, style

Front 30

what are the male parts of a plant?

Back 30

Stamen: fliament, anther

Front 31

what other parts does a plant have?

Back 31

leaves, petals, roots, stem, sepal

Front 32

what is the importance of plants?

Back 32

to atract insects for pollination
