What is an advantage of sexual reproduction for a population of flowering plants in the wild?
A disease is less likely to affect the whole population
Large numbers of offspring can be produced quickly
Pollen can easily be transferred within the same flower
The offspring show genetic variety
Which statement about sexual reproduction is correct?

C
D
Which of these are correct for Sexual reproduction?
involves gametes
always involves only one parent
results in the formation of a zygote
includes the process of fertilisation
only occurs in animals
State the name of the process that involves the fusion of the nuclei of two gametes (sex cells) to form a zygote and the production of offspring that are genetically different from one another

A plant develops seeds and fruit after pollination has occurred.
Name one agent of pollination
(a)
The pollen grains of wind and insect pollinated flowers are different.
Suggest one feature that would help pollen grains be dispersed by wind
(a)
Where does fertilisation occur in a flowering plant?
anther
bud
ovule
stigma
Which part of a flower produces pollen grains?
anther

small
Which of these are an advantage of Asexual reproduction?
Offspring have greater genetic variation
Offspring retain the genetic adaptions of the parent
Offspring can have the same valuable characteristics the parents has to give advantage in the environment
Greater variation mean adaptability to changing environmental conditions
Large numbers of offspring can be produced quickly
Which of these are an advantage of Sexual reproduction?
Offspring have greater genetic variation
Offspring retain the genetic adaptions of the parent
Offspring can have the same valuable characteristics the parents has for the environment
Greater variation mean adaptability to changing environmental conditions
Large numbers of offspring can be produced quickly
Which of these are disadvantages of Sexual reproduction
Genetic disadvantages are passed onto offspring eg: susceptibility to a disease
Have to spend time and energy looking for a mate
Offspring may have variation which does not give an advantage when the environmental conditions change
Energy may be used producing gametes which do not get fertilised and develop into offspring
Lack of genetic variety means it is harder for natural selection to happen in response to environmental changes
