Reproduction Of The Flowering Plant

Question 1

Function of stigma

Answer 1

Place where pollen grain lands

Question 2

Function of ovary

Answer 2

Contains one or more ovule (embryo develops here)

Question 3

Function of ovule

Answer 3

Produces egg

Question 4

Function of anther

Answer 4

Produces pollen grains

Question 5

Function of filament

Answer 5

Supports anther

Question 6

Function of petal

Answer 6

Protects other parts, if animal pollinated it is brightly coloured

Question 7

Function of sepal

Answer 7

Protects flower when in bud

Question 8

Receptacle function

Answer 8

Supports the flower

Question 9

Nectary function

Answer 9

Produces sugary substance called nectar to attract insects

Question 10

Are the cells lining the inside of the anther diploid or haploid

Answer 10

Diploid

Question 11

What process produces pollen grains in the anther

Answer 11

Meiosis , creates haploid pollen grains

Question 12

How are the male gamete nuclei formed from the pollen grain

Answer 12

Mitosis

Question 13

What happens to the anther when the pollen grains develop

Answer 13

Anther splits and peels back to expose pollen

Question 14

What does a seed develop from

Answer 14

Ovule

Question 15

Difference between endospermic and non endospermic seeds

Answer 15

Endospermic: contains some endosperm when fully formed

Non- endospermic: doesn’t contain endosperm when fully formed

Question 16

3 factors necessary for germination

Answer 16

Correct temp., water, oxygen

Question 17

What part of the embryo plant does the root develop from

Answer 17

Radicle

Question 18

What part of flower develops into fruit

Answer 18

Ovary

Question 19

What happens to the two polar nuclei in the carpel

Answer 19

Fuse with a sperm nuclei to form a triploid endosperm

Question 20

Plant that uses wind dispersal

Answer 20

Grass

Question 21

Plant that uses animal dispersal

Answer 21

BlackBerry

Question 22

Why is it important for plants to disperse their seeds

Answer 22

Avoid competition with parent plant

Question 23

3 Advantages of dormancy

Answer 23

Plants can avoid harsh winter
Allows embryo time to fully develop
Provides time for seed dispersal

Question 24

Why is cross pollination better than self pollination

Answer 24

Variation and vigour

Question 25

Why is water needed for germination

Answer 25

Allow enzyme reactions to occur

Question 26

One method used to form seedless fruit

Answer 26

Growth regulator

Question 27

Location in seed where food is stored

Answer 27

Endosperm or cotyledon

Question 28

What carb is likely to be stored in a seed

Answer 28

Starch

Question 29

Role of fruit

Answer 29

Protect seed and aid in dispersal

Question 30

3 characteristics of a wind pollinated flower

Answer 30

Small or absent leaves, not brightly coloured Large amounts of dry pollen Anthers outside of petals

Question 31

3 characteristics of animal pollinated flower

Answer 31

Large bright petals Scented Nectaries small amounts of sticky heavy pollen

Question 32

Why is digestion necessary in a germinating seed

Answer 32

Products needed in embryo for respiration and production of new structures

Question 33

3 ways that fruit are involved in seed dispersal

Answer 33

Succulents are fleshy and eaten by animals Dry pea pods pop Grass like cereals dispersed on wind

Question 34

What is the tests formed from

Answer 34

Integumentary
