reproduction in plants

Question 1

Stamen

Answer 1

the male reproductive organ of a plant

Question 2

Anther

Answer 2

produces
stores and releases pollen

Question 3

Filament

Answer 3

supports the anther and holds it in position

Question 4

stigma

Answer 4

the sticky structure which traps pollen during pollination

Question 5

style

Answer 5

supports the stigma and grows a pollen tube after pollination

Question 6

ovary

Answer 6

produces and stores ovules

becomes the fruit after fertilisation

Question 7

ovule

Answer 7

the female gamete of a plant

Question 8

petal

Answer 8

leaf which has a bright colour to attract animals to a flower

Question 9

sepal

Answer 9

leaf which protects a flower when it is a bud

Question 10

pollination

Answer 10

the transfer of pollen from an anther to a stigma of a flower

Question 11

wind pollination

Answer 11

When pollen is transported by wind,

e.g. wheat, rice, corn and grass

Question 12

insect pollination

Answer 12

insects pick up pollen from the male anther of a flower. When they visit a flower with a stigma (female reproductive part of a flower) the pollen is transferred from the insect to the sticky surface of the stigma. This results in fertilization and the formation of a seed.

Question 13

nectar and nectary

Answer 13

nectary produces sweet nectar

nectar is a sweet liquid which encourages animals to visit flowers

Question 14

pollen

Answer 14

male gamete of plants

Question 15

fertilisation

Answer 15

process which occurs when the nuclei of the pollen and the ovule fuse

Question 16

what doe the fertilised ovule divide (by mitosis) to form

Answer 16

embryo

Question 16

what does the ovary form after fertilisation in the ovule

Answer 16

fruit

Question 17

seed

Answer 17

produced by an embryo and contains genetic material and a food store of starch which powers germination

Question 18

required things for germination

Answer 18

warmth

oxygen

water

Question 19

germination

Answer 19

the process where a seed starts to grow into a plant

Question 20

describes the position of the sex organs in an insect pollinated flower

Answer 20

inside the petals

Question 20

describe the structure and position of a stigma in a wind pollinated flower

Answer 20

long and feathery and hangs outside the flower

Question 21

describes the position of the sex organs in a wind pollinated flower

Answer 21

outside the petals

Question 22

pollen tube

Answer 22

the structure which grows down the style after pollination has occurred. It transfers the pollen nucleus to the ovule

Question 23

Fill in the missing word. It is an advantage to most plants to cross pollinate because it creates ..................... in the population.

Answer 23

Variation

Question 24

cross pollination

Answer 24

the transfer of pollen from an anther to a stigma of a flower of a different plant of the same species
