Here are 10 one-word answer type questions from the topic Pollination along with their answers and explanations:
Topic: Pollination
Pollination is the process of transfer of pollen grains from the anther of one flower to the stigma of the same or another flower. It is of two types – self-pollination and cross-pollination. Pollination is carried out by agents like wind, water, and insects.
1. Question: What is the transfer of pollen grains from anther to stigma called?
Answer: Pollination
Explanation: Pollination is the process in which pollen grains are transferred from the anther (male part) to the stigma (female part) of a flower. It is essential for fertilisation in plants.
2. Question: In which type of pollination do pollen grains transfer from the anther to the stigma of the same flower?
Answer: Self-pollination
Explanation: In self-pollination, pollen grains are transferred to the stigma of the same flower or another flower of the same plant.
3. Question: What is the pollination called when pollen grains are transferred from the anther of one flower to the stigma of another flower of the same kind?
Answer: Cross-pollination
Explanation: In cross-pollination, pollen grains move from one plant to another plant of the same species with the help of agents like wind, water, or insects.
4. Question: Name the reproductive part of the plant where pollen grains are produced.
Answer: Anther
Explanation: Anther is a part of the stamen (male reproductive part) and it produces pollen grains.
5. Question: Name the part of the flower where pollen grains land during pollination.
Answer: Stigma
Explanation: Stigma is the top part of the pistil (female reproductive part) where pollen grains stick during pollination.
6. Question: What type of flowers have both male and female reproductive parts?
Answer: Bisexual
Explanation: Flowers that have both stamen (male part) and pistil (female part) are called bisexual flowers. Example: Rose, Mustard.
7. Question: What do we call flowers that have either male or female reproductive parts?
Answer: Unisexual
Explanation: Unisexual flowers contain either stamens or pistils, not both. Example: Papaya, Cucumber.
8. Question: What protects pollen grains from drying up?
Answer: Tough coat
Explanation: Pollen grains have a tough protective coat which prevents them from drying and helps them to survive during transfer.
9. Question: Name any one agent of pollination.
Answer: Insects
Explanation: Insects like bees and butterflies help in carrying pollen grains from one flower to another during pollination.
10. Question: What is the process of fusion of male and female gametes called after pollination?
Answer: Fertilisation
Explanation: After pollination, the male and female gametes fuse to form a zygote. This process is called fertilisation.
