Final Assessment: Reproduction in Plants

Recall and Core Ideas

Question 1mcq

A rose plant forms seeds after flowers are pollinated, while a potato plant can grow from an eye on a tuber. Which comparison is correct?

A.Rose shows sexual reproduction; potato shows vegetative propagation.

B.Rose shows asexual reproduction; potato shows sexual reproduction.

C.Both examples show only sexual reproduction.

D.Both examples show reproduction without any parent plant.

Question 2mcq

Which feature best separates sexual reproduction in plants from asexual reproduction?

A.Asexual reproduction always needs flowers.

B.Sexual reproduction involves fusion of male and female gametes.

C.Sexual reproduction produces identical clones only.

D.Asexual reproduction always produces seeds.

Question 3mcq

A student says, “All plant reproduction needs seeds.” Which example disproves this statement?

A.Pea plants forming seeds in pods

B.Mango seeds sprouting into seedlings

C.Bryophyllum growing new plants from leaf buds

D.Mustard flowers forming fruits

Question 4mcq

In bread mould, tiny dust-like structures are released from black sporangia. What method of asexual reproduction is this?

A.Budding

B.Fragmentation

C.Pollination

D.Spore formation

Question 5mcq

Which pair correctly matches the plant/organism with asexual reproduction?

A.Yeast — budding

B.Spirogyra — seed dispersal

C.Potato — pollination

D.Bread mould — fertilisation

Question 6mcq

A gardener wants many sugarcane plants with the same useful traits as the parent. Which method is most suitable?

A.Waiting only for random seed dispersal

B.Planting stem cuttings with nodes

C.Removing all buds from stems

D.Keeping the stems in a dry box

Processes and Observations

Question 7mcq

In a flower, which part produces pollen grains?

A.Ovary

B.Sepal

C.Anther

D.Stigma

Question 8mcq

A diagram shows a swollen basal part of the pistil containing ovules. Which label should be used?

A.Petal

B.Filament

C.Anther

D.Ovary

Question 9mcq

Which set contains only female reproductive parts of a flower?

A.Stigma, style and ovary

B.Anther, filament and sepal

C.Petal, sepal and anther

D.Filament, stigma and petal

Question 10mcq

Pollen from the anther of one flower reaches the stigma of another flower of the same kind. This is called:

A.Self-pollination

B.Cross-pollination

C.Fertilisation

D.Germination

Question 11mcq

Why do many brightly coloured flowers also produce nectar?

A.To stop all seed formation

B.To make roots absorb more water

C.To attract insects that help transfer pollen

D.To change petals into fruits

Question 12mcq

A flower is covered with a paper bag before it opens. The student wants to prevent which process?

A.Germination inside the seed

B.Absorption of minerals by roots

C.Breaking of rocks into soil

D.Pollination from outside pollen

Applications and Calculations

Question 13mcq

What happens during fertilisation in a flowering plant?

A.Male and female gametes fuse to form a zygote.

B.Pollen grains become petals immediately.

C.The sepals turn into roots.

D.The stem changes into an anther.

Question 14mcq

After fertilisation, which change is correctly matched?

A.Anther becomes root and stigma becomes leaf.

B.Ovule becomes seed and ovary becomes fruit.

C.Petal becomes pollen and sepal becomes zygote.

D.Style becomes seed and filament becomes fruit.

Question 15mcq

A tomato contains many seeds inside a fleshy part. Which explanation is best?

A.The seeds were made by leaves only.

B.Each seed was a petal before pollination.

C.Many ovules in the ovary developed into seeds.

D.The fruit formed before pollination and no fertilisation occurred.

Question 16mcq

Why is seed dispersal useful for plants?

A.It prevents all seeds from germinating.

B.It makes seeds lose stored food.

C.It stops plants from reproducing sexually.

D.It reduces overcrowding and competition near the parent plant.

Question 17mcq

A seed has a wing-like structure and is light. Which dispersal agent is most likely?

A.Wind

B.Heavy rainfall only

C.A magnet

D.Electric current

Question 18mcq

Why do some fruits have hooks or spines on their seeds?

A.To perform photosynthesis in darkness

B.To cling to animal fur or clothes for dispersal

C.To absorb pollen from soil

D.To become heavier and fall near the parent

Reasoning and Misconceptions

Question 19mcq

Which set of conditions is generally needed for seed germination?

A.Only bright sunlight and no water

B.Only soil colour and wind

C.Water, air and suitable temperature

D.No air and freezing temperature

Question 20mcq

In an experiment, seeds kept on dry cotton did not sprout, while seeds on moist cotton did. What was the missing condition?

A.Carbon dioxide only

B.Pollination

C.Petal colour

D.Water

Question 21mcq

A jar of soaked seeds is tightly sealed with no air. Germination is poor. Which conclusion is best?

A.Seeds need air for germination.

B.Seeds do not need water.

C.Seeds germinate only in ice.

D.Seeds need pollination after soaking.

Question 22mcq

A farmer grows new banana plants from suckers instead of seeds. What advantage does this give?

A.The plants cannot grow roots.

B.New plants keep the useful traits of the parent plant.

C.It guarantees cross-pollination every time.

D.It stops all fruit formation.

Question 23mcq

Assertion: Seed dispersal helps a plant species spread to new places. Reason: Dispersed seeds may find more space, light and nutrients.

A.Both are true, but the reason does not explain the assertion.

B.Assertion is true, but reason is false.

C.Both assertion and reason are true, and the reason explains the assertion.

D.Assertion is false, but reason is true.

Question 24mcq

A student finds small plantlets on the edge of a Bryophyllum leaf. Which conclusion is most scientific?

A.The plantlets prove that all plants reproduce only by seeds.

B.The leaf is acting as a flower stigma.

C.The plant is showing seed dispersal by wind.

D.The leaf buds can develop into new plants by vegetative propagation.
