Plants

Question 1

Flower

Answer 1

Purpose is for reproduction , it makes seeds and contains the female and males sex organ

Question 2

Leaf

Answer 2

Makes food (photosynthesis) , cools the plant when water vapor passes through it , allows the exchange of carbon dioxide to oxygen and the leaf stores food (Eg - lettuce)

Question 3

Fruit

Answer 3

Protects the seeds provides food for the seeds (Eg - apples the seeds are inside the apple)

Question 4

Bud

Answer 4

Allows new leaves and flowers to grow

Question 5

Stem

Answer 5

Allows the transport of food , water and minerals around the plants . It also supports the plant and holds of upright and stems sometimes store food

Question 6

Roots

Answer 6

Anchor and support the plant , they can take in water , nutrients and sometimes store food

Question 7

Transport in plants

Answer 7

These are vessels in a plant , the xylem and phloem

Question 8

Xylem

Answer 8

Water is absorbed the light the roots and travels to the leaves , minerals from the soil are dissolved in the water and travel to the leaves

Question 9

Phloem

Answer 9

Food from the leaves travel through this to other parts of the plant

Question 10

Transpiration

Answer 10

Is the loss of water vapor from the stomata on the underside of the leaves

Question 11

Stomata

Answer 11

Holes on the underside of the leaves

Question 12

Transportation stream

Answer 12

The flow of water from the roots up to through the plants and out the leaves

Question 13

Stimulus

Answer 13

Anything that cause a reaction in a organism . Plants respond to the stimuli of light and gravity

Question 14

Stems tropism

Answer 14

Stems are positively phototropic and negatively geotropic

Question 15

Roots tropism

Answer 15

Roots are negatively phototropic and positively geotropic

Question 16

Geotropic

Answer 16

Attracted to the gravity

Question 17

Phototropic

Answer 17

Attracted to sunlight

Question 18

Why is geotropism good

Answer 18

Makes sure the roots go down and get all the minerals and water in the soil . The plant is anchored to the soil and won’t fall over

Question 19

Why is phototropism good

Answer 19

It makes sure the plants gets light so they can make food

Question 20

Photosynthesis

Answer 20

The process where plants make food using the sun light

Question 21

Chlorophyll

Answer 21

Green chemical needed in photosynthesis process and can be found in chloroplasts in the plant cell

Question 22

How are leaves designed for photosynthesis

Answer 22

They are flat and thin to allow sunlight to get through them . The have little holes called stomata to let carbon dioxide in and oxygen out

Question 23

Male cells

Answer 23

Pollen

Question 24

Female cells

Answer 24

Egg

Question 25

Sepal

Answer 25

Protects the flower before it blooms

Question 26

Petals

Answer 26

Colored and scented to attract insects

Question 27

Male parts

Answer 27

Stamen made up of filaments and anthers

Question 28

Filament

Answer 28

Holds up the anthers

Question 29

Anther

Answer 29

Makes the pollen

Question 30

Female parts

Answer 30

Carpel , made up of the stigma , style and ovary

Question 31

Ovary

Answer 31

Makes the egg or ovule

Question 32

Stigma

Answer 32

Pollen lands and sticks to it

Question 33

Style

Answer 33

Makes a tube for the pollen (male gamete) to travel down to the egg ( female gamete )

Question 34

Pollination

Answer 34

The transfer of the pollen from the stamen (anther) of one plant to the carpel (stigma) of another

Question 35

Fertilization

Answer 35

Is the fusion of the male gamete nucleus and the female gamete nucleus to form a zygote

Question 36

Zygote

Answer 36

When the male and female nucleus fuse they for a zygote . The zygote divides and develops into a plant embryo

Question 37

Plumule

Answer 37

Becomes the plant shoot

Question 38

Radicle

Answer 38

Becomes the plant root

Question 39

Seed

Answer 39

After fertilization the fertilized egg becomes the plant seed

Question 40

Fruit

Answer 40

The ovary swells to become the fruit

Question 41

Functions of the fruit

Answer 41

• Protects the seed
• Allows the seed to be carried away
• Provides food for the seed

Question 42

2 types of fruit

Answer 42

• Fleshy ( strawberry , melon )

- Dry ( dandelion , sycamore ( seeds ) )

Question 43

Seed dispersal

Answer 43

The way plants spread their seeds around . They need to be carried away so they won’t compete with the parent plant for water , light and minerals
