Which is a disadvantage of asexual reproduction?

In a population, disease will spread rapidly

Insect pollinated plants contain nectar to attract mammals. Explain why.

False. It attracts insects not mammals.

What is the function of the ovary in reproduction?

It produces eggs for fertilisation

To release pollen into the wind

What is the full definition of asexual reproduction?

Production of genetically identical offspring from 1 parent

What are the functions of part 6?

Supports the stigma and connects it to ovary

Questions 25

Answers

1
What is fertilisation?
The act done by a male and female
The transfer of pollen grains from anther to stigma
Fusion of gamete nuclei
Formation of a diploid nuclei
2
Which is a disadvantage of asexual reproduction?
In a population, disease will spread rapidly
Plants get new traits, some of which may be harmful
Won't have a plant to mate with :( #lonely (nothing more)
New beneficial traits pass onto offspring really slowly
3
Insect pollinated plants contain nectar to attract mammals. Explain why.
False. It attracts insects not mammals.
True. To pollinate it.
False
True
4
What is the function of the ovary in reproduction?
It develops into eggs after a period of 4 weeks
It produces eggs for fertilisation
It absorbs the hormones: oestrogen and progesterone
It is the site where pollen is given first before to stigma
5
Is self-pollination an example of asexual reproduction?
Yes
No
6
What is a function of part 7 (the ovary)?
The site which receives pollen grains from the anther
Digests hormones: oestrogen and progesterone
Develops into a fruit and protects the ovules
Releases hormones: oestrogen and progesterone
7
What does the radicle develop into?
Root of the plant
Flowers of the plant
Leaves of the plant
Root cortex cells
8
What is the cotyledon?
Holds the seed together
Food store
Water store
For photosynthesising
9
What is the food store made up of?
glucose
glycogen
starch
maltose
10
Why do the anthers of a wind-pollinated flower dangle out?
To release pollen into the wind
Lack of water, sticking out shows that it is dehydrated
To reach out to the stigma
To brush against passing animals
11
What is the full definition of asexual reproduction?
Combination of 2 haploid nuclei to form a diploid zygote
Production of partially-identical offspring from 1 parent
Self fertilisation
Production of genetically identical offspring from 1 parent
12
Why is oxygen important for germination
to repay oxygen debt
to breathe
photosynthesis to make glucose
respiration to release energy
13
What are the functions of part 6?
Supports the stigma and connects it to ovary
Supports the stigma and connects it to ovules
Gives the stigma its upright shape
Renders the ovary attractive
14
Why is water important for germination?
To activate enzymes
To hydrate the seed
To make the seed bigger
Because it's thirsty
15
What does the plumule develop into?
Flowers of the plant
Leaves of the plant
Shoot of the plant
Root of the plant
16
Why does the stigma hang outside the flower?
To make contact with the anther
To catch the drifting pollen
It is dehydrated
So that it can catch other pollens out of reach
17
What is the function of the sepal?
Protect the flower when in a bud
Protect the ovary of the flower
Guarding the ovules
Make the flower look attractive to insects
18
Which is an advantage of asexual reproduction?
Plants won't catch diseases from other plants
Production of offspring with new traits
Genetically varied offspring
Fast reproduction rate
19
What is your favourite easter egg?
Lindt bunny
Creme egg
Malteser egg
Smartie egg
20
What are the functions of petals?
Attracts and repels certain pollinators
It protects certain parts of the flowers
Large and brightly coloured for insects
Attracts every kind of pollinator
21

False
22
What are parts 1,2 and 3 respectively?
Pollen, Anther, Petal
Pollen, Filament, Sepal
Anther, Filament, Stamen

23
What is pollination?
Insects come and take honey from the flowers
Transfer of pollen grains from anther to stigma
Transfer of pollen from stigma to anther
Transfer of gametes from anther to stigma
24
What are the specific conditions a seed needs to germinate?
Air, water, light
Air, water, warmth
Oxygen, water, warmth
Oxygen, water, light
25
What are parts 4,5 and 6 respectively?
Petal, Stigma, Ovary
Sepal, Stigma, Style
Stamen, Carpel, Style
Stamen, Sepal, Style
