Reproduction in flowering plant

Meiotic cell division occurs in

• Sepal and Petal

• Stigma and Anther

• Nectary and Ovary

• Anther and Ovules

Which of the following characteristic(s) indicate that the flower is insect-pollinated?

(You can choose more than one answers)

• Anther and stigma are enclosed with petals

• Ovules occurs in small numbers

• Petal is large and conspicuous

• Presence of nectaries

Which structure(s) will usually wither after fertilization?

(You can choose more than one answers)

• Ovary

• Sepal

• Petal

• Anther

Which of the following are the advantage(s) of seed dispersal?

(You can choose more than one answer)

• It reduces competition

• It increases the chances of genetic variations

• It prevents the spread of diseases

• It allows plants to colonize new areas

If the diploid chromosome number of a flowering plant is 24, which of the following structure has 12 chromosomes?

• An anther

• An embryo

• A stigma

• A pollen grain

With reference to the above diagram, which of the following characteristics indicates that this flower is adapted to wind pollination?

• It is bisexual flower

• It’s stigma hangs outside the flower

• It anthers lie below the stigma

• Its anthers produce numerous pollen grains

Which fruits above carry seeds that are dispersed by animals?

• 1 and 2

• 2 and 3

• 3 and 4

• 4 and 1

Pollen grains usually produce in large number because

• The species can explore new environments

• Competition among the new plants can be reduced

• They can help the dispersal of new plants

• They can have a greater chance of reaching other flowers

Which of the following statement about fruit formation is correct?

• Seed coat is developed from ovary wall

• Fruit wall is developed from ovary wall

• Seed is developed from pollen grains

• Fruit wall is developed from calyx

Which of the following process concerning reproduction in flowering plants will lead to variation in offspring?

(You can choose more than one answers)

• Formation of gamete

• Fusion of gametes from the same plant

• Fusion of gamete from two plants of same species

• Artificial vegetative propagation
