reproduction in flowering plants

Question 1

how do flowering plants reproduce

Answer 1

flowering plants carry out sexual reproduction and can reproduce from seeds

Question 2

what are the four processes in the life cycle of a flowering plant

Answer 2

pollination,fertilisation, seed dispersal, germination

Question 3

male parts of a flower

Answer 3

anther , filament

Question 4

female parts of a flower

Answer 4

stigma , style , ovary , ovule

Question 5

function of an anther

Answer 5

produces pollen grains and stores them in pollen sacs

Question 6

function of a filament

Answer 6

holds the anther up

Question 7

stigma

Answer 7

receives pollen grains

Question 8

style

Answer 8

connects the stigma to the ovary

Question 9

ovary

Answer 9

protects the ovule and become the fruit after fertilisation

Question 10

ovule

Answer 10

becomes the seed after fertilisation

Question 11

petal

Answer 11

attracts pollinators such as birds and insects to the flower

Question 12

flower stalk

Answer 12

holds the flower up so that it can be easily detected by pollinator

Question 13

what is pollination

Answer 13

pollination occurs when pollen grains are transferred from the anther of one flower to the stigma of the same flower or another of the same kind.

Question 14

insect pollinated flower characteristics

Answer 14

large, brightly coloured, scented to attract insects, anthers do not hang out of the flowers, stigma is sticky in order to catch pollen grains

Question 15

wind pollinated flower characteristics

Answer 15

small, dull coloured, no scent, anthers hang out of the flower so that pollen grains are easily shaken free and carried by the wind, stigma is large and feathery to catch pollen grains floating in the air.

Question 16

Process of insect pollination

Answer 16

when an insect visits a flower to feed on the nectar, pollen grains from the anther stick to the insects hairy body. The pollen grains are brushed off onto the stigma of the same flower or another flower that the insect visits

Question 17

process of wind pollination

Answer 17

the filament sways in the slightest wind and pollen grains are shaken free

Question 18

where does self pollination occur

Answer 18

occurs within the same flower or between flowers of the same plants

Question 19

advantages of self pollination

Answer 19

does not depend on birds insects or wind

Question 20

where cross pollination occurs

Answer 20

occurs between flowers of seperate plants of the same kind

Question 21

advantages of cross pollination

Answer 21

the young plant might combines the good qualities of both parent plants. better quality seeds may be better able to adapt to its environment

Question 22

process of self pollination

Answer 22

when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant

Question 23

process of cross pollination

Answer 23

transfer of pollen from the anther of one flower to the stigma of another flower on a different individual of the same species.

Question 24

what is fertilisation

Answer 24

fertilisation is the process in which a male reproductive cell fuses with a female reproductive cell (egg cell)

Question 25

what does the ovules in ovary develop into after fertilisation?

Answer 25

seed

Question 26

what happens after fertilisation

Answer 26

most of the flower parts such as the petals, style and stigma usually wither and drop off, except the ovary

Question 27

why do seeds need to be dispersed of scattered away from the parent plants

Answer 27

to prevent overcrowding, which can lead to competition for light, water and space and can grow in a new and more favourable place

Question 28

characteristics of fruits and seeds dispersed by animals

Answer 28

juicy, fragrant, sweet or brightly coloured fruit, hard seeds , have hooks or stiff hair

Question 29

what is germination

Answer 29

germination is the first stage in the development of a plant from a seed

Question 30

a seed does not need ______ to germinated

Answer 30

light

Question 31

seeds need ____ , _____ and ______ to germinate

Answer 31

water , oxygen, warmth (WOW)
