Reproduction: Final Assessment

Section A: Plant Reproduction Review

Question 1mcq

Why does sexual reproduction usually create more variation than asexual reproduction?

A.It makes all offspring exact copies of each other.

B.It combines genetic material from two parents through gametes.

C.It avoids the formation of gametes.

D.It produces offspring from only one parent without any mixing.

Question 2mcq

A student says, “Fragmentation and budding are the same because both make new individuals.” Which correction is best?

A.In fragmentation, a body breaks into pieces; in budding, a small outgrowth grows from the parent.

B.Fragmentation always produces seeds, but budding never produces offspring.

C.In both methods, two gametes must fuse first.

D.Budding happens only in flowering plants, while fragmentation happens only in humans.

Question 3mcq

A labelled diagram shows stigma, style, ovary and ovule together. Which reproductive structure is being shown?

A.Petal

B.Sepal

C.Stamen

D.Pistil

Question 4mcq

Why do many insect-pollinated flowers have bright petals and nectar?

A.To stop fertilisation from happening

B.To absorb more water from soil

C.To attract insects that can carry pollen from flower to flower

D.To make seeds lighter for wind dispersal

Question 5mcq

A flower is pollinated but fertilisation does not occur. Which result is most likely?

A.The pollen grain will become a seed directly.

B.Normal seed formation will not take place.

C.The ovule will surely become a seed without gamete fusion.

D.The anther will turn into a fruit.

Question 6mcq

A student writes, “The ovary becomes the seed.” What is the best correction?

A.The ovary becomes the fruit, while the ovule becomes the seed.

B.The ovary becomes pollen, while the ovule becomes an anther.

C.The ovary becomes a petal, while the ovule becomes a sepal.

D.The ovary and ovule both disappear after fertilisation.

Section B: Seeds and Ecology Review

Question 7mcq

A seed has hooks that cling to an animal’s fur. Which dispersal method does this show?

A.Dispersal by wind only

B.Dispersal by explosion only

C.Dispersal by water only

D.Dispersal by animals

Question 8mcq

If pollinator populations sharply decrease in an area, what is a likely effect on many flowering plants?

A.Pollination will become unnecessary for all flowering plants.

B.All plants will immediately switch to animal reproduction.

C.Fewer flowers may be successfully pollinated, reducing seed and fruit formation.

D.Every flower will produce more seeds without pollen.

Question 9mcq

Why are testes located in a scrotal sac outside the abdominal cavity?

A.The testes must be inside the stomach for digestion.

B.Sperm formation works best at a temperature slightly lower than normal body temperature.

C.Sperm need bright light to form.

D.The scrotum changes sperm into eggs.

Question 10mcq

Which statement correctly describes the uterus?

A.It is the organ where the embryo can implant and develop during pregnancy.

B.It releases pollen grains.

C.It is the tube that produces eggs.

D.It produces sperm cells.

Question 11mcq

What is fertilisation in humans?

A.Breakdown of food to release energy

B.Development of a baby after birth

C.Release of an egg from the ovary only

D.Fusion of a sperm cell with an egg cell to form a zygote

Question 12mcq

Why does a zygote have genetic information from both parents?

A.It is produced by budding from the father.

B.It forms without any nucleus.

C.It forms when sperm and egg nuclei fuse.

D.It forms from only one body cell of the mother.

Section C: Human Reproduction Review

Question 13mcq

What is implantation?

A.Movement of seeds by wind

B.Attachment of the developing embryo to the lining of the uterus

C.Formation of sperm in testes

D.Release of pollen from anther

Question 14mcq

Why is the uterus lining important during early pregnancy?

A.It provides a place where the embryo can attach and receive support for development.

B.It produces pollen grains.

C.It carries sperm from testes.

D.It forms the scrotum.

Question 15mcq

If fertilisation does not occur, what usually happens to the thickened uterus lining?

A.It changes into sperm.

B.It becomes a seed coat.

C.It becomes a fruit.

D.It breaks down and is released during menstruation.

Question 16mcq

Why is menstruation a normal biological process and not a disease?

A.It means fertilisation always happened.

B.It happens only when a person has an infection.

C.It is part of the reproductive cycle when the uterus lining is shed if pregnancy does not occur.

D.It is caused by pollen entering the uterus.

Question 17mcq

Why is variation useful for a species?

A.Variation means all individuals are identical.

B.Some variations may help individuals survive better when the environment changes.

C.Variation stops reproduction permanently.

D.Variation makes every organism weaker.

Question 18mcq

A disease affects plants with one particular inherited trait. Why might a varied population survive better?

A.Some plants may have different traits that make them less affected by the disease.

B.Disease cannot affect any sexually reproducing organism.

C.All plants in a varied population are exactly the same.

D.Variation prevents plants from making seeds.

Section D: Health and Applications Review

Question 19mcq

Which statement shows a responsible attitude toward reproductive health?

A.Avoid learning about body changes.

B.Believe every rumour shared online.

C.Treat menstruation as a shameful disease.

D.Use reliable information, maintain hygiene and seek help for health concerns.

Question 20mcq

Which statement is scientifically and socially responsible?

A.Birth control should be discussed only through rumours.

B.All birth control methods work in the same way.

C.Birth control decisions should be based on accurate health information and respect.

D.Contraception is related only to plants.

Question 21mcq

Which feature makes a reproductive system diagram most useful for learning?

A.Decorative colouring without labels

B.Clear labels connected to the correct parts

C.Only a title with no parts shown

D.Labels placed randomly around the page

Question 22mcq

A student labels the anther as the ovary in a flower diagram. What is the main problem?

A.It confuses the male pollen-producing part with the female ovule-containing part.

B.It uses too many colours.

C.It makes the flower look larger.

D.It shows petals above sepals.

Question 23mcq

Which statement is most appropriate when discussing assisted reproductive technologies in class?

A.They prove that reproductive health does not need doctors.

B.They are the same as seed dispersal in plants.

C.They should be explained through jokes and rumours.

D.They are medical supports that should be discussed respectfully and scientifically.

Question 24mcq

Why should students avoid making fun of infertility or medical reproductive support?

A.Because only plants can face reproductive problems.

B.Because infertility is always caused by laziness.

C.Because reproductive health issues can be sensitive and deserve respect and accurate understanding.

D.Because medical science has no role in reproduction.
