Flashcards in Chapter 17 Deck (27):
1

apical meristems

Growth-producing regions of cell division found near the tips of stems and roots

2

vascular tissue

a network of thick-walled cells joined into narrow tubes that extend throughout the plant body

3

xylem

vascular tissue made up of dead cells that form microscopic pipes conveying water and minerals up from the roots

4

phloem

vascular tissue consisting of entirely living cells that distributes sugars throughout the plant

5

lignin

Components of some cell walls that thickens and reinforces.

6

gametangia

male and female gametes in mosses and ferns

7

pollen grains

structures in pines and flowering plants that contain the sperm-producing cells

8

embryophytes

the fertilized egg that develops into an embryo while attached to and nourished by the parent plant.

9

sporangia

spores within protective structures

10

spore

a cell that can develop into a new organism without fusing with another cell

11

bryophytes

seedless, nonvascular plants

12

vascular plants

contain lignin-hardened vascular tissues

13

seedless vascular plants

Have vascular tissues but no seeds. Mosses and ferns

14

gymnosperms

Earliest seed plants that are not produced in specialized chambers.

15

angiosperms

Flowering plants whose seeds are in protective chambers.

16

alteration of generations

Where the diploid and haploid stages are distinct.

17

gametophyte

The haploid generation of the plant that produces gametes

18

sporophyte

The diploid generation that produces spores

19

ovules

Parts of the ovulate cone

20

pollination

occurs when a pollen grain lands on an ovulate scale and enters an ovule

21

seed coat

the ovules integument

22

sepals

the outer layer of the floral circle

23

petals

the area below the sepals

24

stamens

the male component of the flower

25

anther

a sac at the top of the filament of the stamen

26

carpal

the female floral reproductive structure

27

ovary

a unique angiosperm adaptation that encloses the ovules
