Bio Chapter 25

Front 1

What is a seed?

Back 1

a reproductive package that contains embryo and a supply of stored foods inside a protective coating.

Front 2

What is the reproductive cycle of seed plants?

Back 2

cone flowers,meiosis spores pollen eggs haploid(n),mitosis gametophytes gametes haploid(n), fertilization zygote diploid (2n),mitosis sporophyte diploid (2n),and alternates.

Front 3

Where are the gametophytes of seed bearing plants

Back 3

The gametophytes live inside the sporophytes(common large plants you see around you)

Front 4

Explain why seed bearing plants are able to live everywhere on Earth

Back 4

they have the ability to reproduce without water

Front 5

gametophytes live inside special parts of the sporophyte-plant parts known as

Back 5

cones and flowers

Front 6

What kinds of spores are produced by seed plants

Back 6

pollen and egg

Front 7

Cones and floweres are home to the __________ generation

Back 7

gametophyte

Front 8

What are the four living divisions of Gymnosperms?

Back 8

Cycads,ginkgoes,gnetophytes and conifers

Front 9

Describe gymnosperms

Back 9

plants that bear their seeds on the surfaces of reproductive structures called scales

Front 10

what does gymnosperm mean

Back 10

naked seed

Front 11

The first seed-bearing plants were known as

Back 11

Seed fern - extinct today

Front 12

Define Cycads

Back 12

palm like plants most common one - sago palm

Front 13

define Ginkgoes

Back 13

Ginkgo biloba may be the oldest living species of seed bearing plants

Front 14

What are conifers

Back 14

sometimes called evergreens- members include spruce,pine,cedar,redwood,fir and yew trees

Front 15

What do male cones produce

Back 15

pollen

Front 16

What do female cones produce

Back 16

eggs

Front 17

Female cones are sometimes called:

Back 17

seed cones because they eventually contain mature seeds

Front 18

What are angiosperms?

Back 18

flowering plant whose seeds develop within a matured ovary (ovary)

Front 19

What is the difference between gynmosperms and angiosperms?

Back 19

gymnosperms have exposed seeds and angiosperms produce seeds encased in a protective tissue of the sporophyte known as the ovary.

Front 20

The combination of seed and ovary is known as a

Back 20

fruit

Front 21

What are the reproductive organs of angiosperms?

Back 21

the Flower

Front 22

Flowers are formed from 4 types of specialized leaves

Back 22

sepals, petals, stamens and carpels

Front 23

Define Sepals

Back 23

structure that encloses and protects the developing flower bud and opens as the flower blooms

Front 24

Define petals

Back 24

one of the white or colorful leaflike parts of a flower

Front 25

Define Stamens

Back 25

male leaf that produces pollen

Front 26

Define filament

Back 26

stamen that emerges from a flower

Front 27

Define anther

Back 27

sac at the tip of a filament where pollen is produced and released

Front 28

Define carpels

Back 28

female leaf of a flower

Front 29

Define ovules

Back 29

the place where female gametophytes are produced

Front 30

Define style

Back 30

the stemlike narrow part of the carpal

Front 31

Define stigma

Back 31

sticky tip of the style of the plant

Front 32

Define pistil

Back 32

female reproductive organ of a flowering plant, composed of ovary, style and stigma

Front 33

What important feature distinguishes the life cycle of an angisperm from life cycle of gymnosperm?

Back 33

double fertilization

Front 34

define endosperm

Back 34

food rich tissue that surrounds the embryo of a plant

Front 35

define double fertilization

Back 35

process of 2 fertilization events taking place inside an embryo sac

Front 36

What is a fruit?

Back 36

if it contains a seed inside the overy wall-ripened ovary that contains angiosperm seeds

Front 37

What reproduces faster angiosperm or gymnosperm?

Back 37

Angiosperm

Front 38

define cotyledons

Back 38

the large seed leaves that contain stored food to nourish the plant embryos of seeds

Front 39

plants that have one cotyledon are know as:

Back 39

monocots

Front 40

Monocots constitute the class monocotyledonae which includes

Back 40

grasses, irises,and cattails, corn, daffadils

Front 41

plants that have two cotyledons are known as

Back 41

dicots

Front 42

the dicots constitute the class dicotyledonae which includes

Back 42

roses,clover, tomotoes, oaks and daisies and the flowering trees such as maple, oak, elm, apple and dogwood.

Front 43

monocots are identified by a single cotyledon as well as:

Back 43

veins in monocot leaves usually lie parallel to each other, monocot flowers usually have floral plantss in multiples of three

Front 44

dicots are identified by having 2 cotyledons as well as:

Back 44

veins usually form a branching network, dicot flowers usually show multiples of 4 or 5
