Plants/check ecology for the rest

Question 1

Flower

Answer 1

If for reproduction,it makes seeds it contains male and female sex organs

Question 2

Leaf

Answer 2

Makes food for the plant,cools the plants when water vapour passes through it,allows the exchange of carbon dioxide and oxygen,leaf stores food (e.g. lettuce cabbage cress and spinach)

Question 3

Fruit

Answer 3

Protects seed and provides food for seeds

Question 4

The bud

Answer 4

Allows new leaves and flowers to grow

Question 5

Stem

Answer 5

The stem allows transport or food water and minerals around food the plant,it also supports the plant and holds it upright,set,stems store food

Question 6

Stimulus

Answer 6

A stimulus is anything that causes a response in an organism,plants respond to the stimuli of light and gravity

Question 7

Shoots tropism

Answer 7

Shoots/stems are positively phototropic,negatively geotropic

Question 8

Roots tropism

Answer 8

Roots are negatively phototropic,positively geotropic

Question 9

Why is geotropism good?

Answer 9

It makes sure plant roots travel down to find water and minerals in soil,having deep roots means the plant is anchored in the soil

Question 10

He is phototropism good?

Answer 10

It makes sure plants get enough light for photosynthesis so that they can make food!

Question 11

Photosynthesis

Answer 11

Is the process where green plants make food using light energy

Question 12

Chlorophyll

Answer 12

Hitch is a green chemical needed for photosynthesis found in chloroplasts in plant cells

Question 13

Sexual reproduction

Answer 13

The flower is the sexual reproduction organ of the plant,male cells called pollen are made here,female cells called egg cells are made here

Question 14

Sepal

Answer 14

Protects the flower before it blooms

Question 15

Petals

Answer 15

Coloured and scented to attract insects

Question 16

Male parts

Answer 16

Stamen made up of filament and anther

Question 17

Filament

Answer 17

Holds up another

Question 18

Anther

Answer 18

Makes pollen

Question 19

Female parts

Answer 19

Carpel,made up of the stigma,style and ovary

Question 20

Ovary

Answer 20

Makes the egg or ovule

Question 21

Stigma

Answer 21

Pollen lands and sticks to it

Question 22

Style

Answer 22

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

Question 23

Pollination

Answer 23

Is the transfer o father pollen from the stamen (anther)of one plant to the carpel (stigma) of another

Question 24

Fertilisation

Answer 24

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

Question 25

Zygote

Answer 25

When the male and female nucleus fuse they form zygote,the zygote divides and develops into the plant embryo

Question 26

Plumule

Answer 26

The plumule will be come the plant shoot

Question 27

Radicle

Answer 27

The radicle will become the plant root

Question 28

Seed

Answer 28

After fertilisation the fertilised egg becomes the seed

Question 29

Fruit

Answer 29

The ovary swells to become the fruit

Question 30

Functions of the fruit

Answer 30

Protects the seeds,allows the seeds to be carried away and provides food

Question 31

2 types of fruit

Answer 31

Fleshy or dry
Strawberry and melons
Dandelion and sycamore

Question 32

Seed dispersal

Answer 32

Is the way plants spread their seeds around,seeds need to be carried away from the parent plant so they won’t compete for space,light,water and minerals

Question 33

Animal dispersal

Answer 33

Happens when fleshy fruits are eaten by animals or birds,the seeds pass unharmed through the animal and come out in faces somewhere else

Question 34

Wind dispersal

Answer 34

Happens when the seeds are carried on the wind examples are the dandelion “parachute” and the sycamore “helicopter”

Question 35

Self dispersal

Answer 35

Some plants explode to release their seeds,example pea pods

Question 36

Water dispersal

Answer 36

When plants produce seeds to float away,example water lilies

Question 37

Germination

Answer 37

Is the growth of seeds into a new plant,seeds need water,oxygen and heat to germinate,the young plant initially gets its food from the seed,once the shoot develops green leaves,it can make its own food

Question 38

Asexual reproduction

Answer 38

Involves only one parent

Question 39

Bulbs

Answer 39

Tulips and daffodils make bulbs which can be planted to make new plants

Question 40

Runners

Answer 40

Strawberry plants and buttercups use runners

Question 41

Clone

Answer 41

Asexual reproduction results in an exact copy of the parent plant,or a clone
