Yes, I have no clue I mean it says ''SELF-pollination'' so idk

List some disadvantages of asexual reproduction

In a population, disease will spread rapidly

What are the functions of part 6?

Supports the stigma and connects it to ovary

Why are the petals so useful to the flower?

Attracts and repels certain pollinators, It protects certain parts of the flowers, It makes the flower look attractive

Transfer of pollen grains from anther to stigma

Answers

1
Insect pollinated plants contain nectar to attract mammals. Explain why.
True. To pollinate it.
False. It attracts insects not mammals.
False
True
2
Why does the stigma hang outside the flower?
So that it can catch other pollens out of reach
To catch the drifting pollen
It is dehydrated
To make contact with the anther
3
What is the function of the sepal?
Protect the ovary of the flower
Protect the flower from drying out of water
Guarding the ovules
Make the flower look attractive to insects
4
What is a function of part 7 (the ovary)?
Develops into a fruit and protects the ovules
The site which receives pollen grains from the anther
Releases hormones: oestrogen and progesterone
Digests hormones: oestrogen and progesterone
5
What is the function of the ovary in reproduction?
It produces eggs for fertilisation
It is the site where pollen is given first before to stigma
It develops into eggs after a period of 4 weeks
It absorbs the hormones: oestrogen and progesterone
6
What does the plumule develop into?
Shoot of the plant
Flowers of the plant
Leaves of the plant
Root of the plant
7
Is self-pollination an example of asexual reproduction?
Yes
No
What do you think?
I have no clue I mean it says ''SELF-pollination'' so idk
8
List some disadvantages of asexual reproduction
Won't have a plant to mate with :( #lonely (nothing more)
In a population, disease will spread rapidly
Plants get new traits, some of which may be harmful
New adaptations pass onto offsprings really slowly
9
What is fertilisation?
The act done by a male and female
The transfer of pollen grains from anther to stigma
Formation of a diploid nuclei
Fusion of gamete nuclei
10
What are parts 1,2 and 3 respectively?
Pollen, Filament, Sepal
Pollen, Anther, Petal
Anther, Filament, Petal
Anther, Filament, Stamen
11
What are the functions of part 6?
Supports the stigma and connects it to ovules
Gives the stigma its upright shape
Renders the ovary attractive
Supports the stigma and connects it to ovary
12
List some advantages from asexual reproduction
Offspring gets new adaptations likes immunity to disease
Production of offspring with new traits
Plants won't catch diseases from other plants
Super fast reproduction rate
13
What does the radicle develop into?
Flowers of the plant
Root of the plant
Root cortex cells
Leaves of the plant
14
Wind pollinated plants have bright, coloured petals
True
False
15
Why are the petals so useful to the flower?
Attracts and repels certain pollinators
Attracts every kind of pollinator
It protects certain parts of the flowers
It makes the flower look attractive
16
What is pollination?
Transfer of pollen grains from anther to stigma
Insects come and take honey from the flowers
Transfer of gametes from anther to stigma
Transfer of pollen from anther to stigma
17
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 brush against passing animals
To reach out to the stigma
18
What is the full definition of asexual reproduction?
Self fertilisation
Production of partially-identical offspring from 1 parent
Combination of 2 haploid nuclei to form a diploid zygote
Production of genetically identical offspring from 1 parent
19
What are the specific conditions a seed needs to germinate?
Air, water, heat
Oxygen, water, warmth
Air, water, warmth
Oxygen, water, heat
20
What are parts 4,5 and 6 respectively?
Sepal, Stigma, Style
Stamen, Carpel, Style
Stamen, Sepal, Style
Petal, Stigma, Ovary
