Front 1

Pollination

Back 1

occurs when a grain of pollen lands on the stigma of a flower

Front 2

Gymnosperms are pollinated by the

Back 2

wind

Front 3

The male part of a flower is called

Back 3

stamen

Front 4

The female part of a flower is called

Back 4

pistil

Front 5

Gymnosperms

Back 5

plants that produce seed that are protected by a cone or a fleshy seed coat

Front 6

Angiosperms

Back 6

plants that have flowers and produce seeds enclosed in the fruit

Front 7

Germination begins

Back 7

when the seed absorbs water and swells

Front 8

Cotyledons

Back 8

special seed leaves that contain stored food

Front 9

Gestation is

Back 9

the period of time between fertilization and the birth of an animal

Front 10

What are animals called that develop in the mother's pouch

Back 10

marsupial mammals

Front 11

What are the animals called that develop inside the mother's body

Back 11

placental mammals

Front 12

asexual reproduction

Back 12

reproduction that involves only one parent

Front 13

binary fission

Back 13

an organism splits in half and becomes two separate organisms

Front 14

budding

Back 14

type of asexual reproduction in which a new organism develops on the parent organism

Front 15

regeneration

Back 15

some sea stars can reproduce this way

Front 16

stolons

Back 16

runners or creeping stems through which strawberries can reproduce

Front 17

vegetative reproduction

Back 17

occurs when part of a plant usually not involved in reproduction develops in to a new plant

Front 18

Parts of a flower

Back 18

anther, filament, stamen, stigma, style, pistil, ovary and ovule, sepals, petals

Front 19

fruit of a plant

Back 19

the part that contains the seed

Front 20

parts of a seed

Back 20

embryo, cotyledons, seed coat

Front 21

Once an egg cell is fertilized what happens to the ovule and the ovary

Back 21

the ovule becomes the seed coat adn the ovary develops into the fruit

Front 22

cross pollination

Back 22

pollen is transferred from an anther of one plant to the stigma int eh flower of another plant

Front 23

self-pollination

Back 23

pollen is transferred from the anther to the stigma of the same flower or another flower on the same plant

Front 24

a spore is different from a seed - How

Back 24

it is smaller, has one cell, and does not contain stored food

Front 25

ferns and mosses reproduce by

Back 25

spores
