5Th Grade Science Chapter 2

Front 1

rhizoid

Back 1

hair like fiber that anchors moss to soil and takes in water from soil

Front 2

spore

Back 2

cell in seedless plant that grows into new plant

Front 3

frond

Back 3

leaf of a fern

Front 4

rhizome

Back 4

underground stem of fern

Front 5

sexual reproduction

Back 5

when female and male cell come together to make a fertilized egg

Front 6

asexual reproduction

Back 6

production of new organism by only one cell (spore)

Front 7

3 things mosses do to help the envronment

Back 7

keep top layer of soil from blowing away
keep moisture in the ground
break up rocks to make fertile soil

Front 8

Mosses grow close to the ground because

Back 8

they are non-vascular so they don't have the tube-like structures to carry water and support the plant

Front 9

how do mosses take in water

Back 9

they take in water through the rhizoids and pass it from cell to cell

Front 10

when a plant alternates between sexual and asexual reproduction

Back 10

alteration of generation

(mosses and ferns reproduce this way)

Front 11

are ferns vascular or non-vascular

Back 11

ferns are vascular

Front 12

What were the first land plants

Back 12

mosses were the first land plant

Front 13

what do the cells of green algae and plants have in common

Back 13

they both have a cell wall that contains cellulose.
they also both store food as starch

Front 14

list two differences between mosses and ferns

Back 14

mosses grow close to the ground and are non-vascular.
ferns grow taller and are vascular

Front 15

In order how do scientists think plant appeared on land

Back 15

1.mosses
2 ferns
3gymnosperm
4 angiosperms

Front 16

what is a seed

Back 16

an underdeveloped plant with stored food sealed in a protective coating

Front 17

angiosperm

Back 17

a seed plant that produces flowers

Front 18

gymnosperm

Back 22

conifers are found mostly in the northern parts of the world

Front 23

are most gymonosperm evergreen or diceduous

Back 23

most are evergreen

Front 24

conifer

Back 24

any group of gymnosperm that produce seeds in cones and have needle like leaves

Front 25

cotyledon

Back 25

a tiny leaflike structure inside a seed of an angiosperm

Front 26

monocot

Back 26

an angiosperm with one cotyledon in each seed

Front 27

dicot

Back 27

an angiosperm with two cotyledons in each seed

Front 28

What is the largest division of the plant kingdom

Back 28

angiosperm is the largest division

Front 29

monocots have this type of vascular system

Back 29

scattered bundles
