Science 4 - Pollination
This quiz titled 'Science 4 - POLLINATION' assesses knowledge on the fundamental aspects of pollination in plants. It covers key concepts such as the parts of a flower, agents of pollination, and the process of pollen transfer. This quiz is designed to enhance understanding of plant reproduction, crucial for students studying biology.
- 1.
What is the term for the transfer of pollen in plants?
- A.
Pollination
- B.
Pollen grains
- C.
Style
- D.
Stamina
Correct Answer
A. PollinationExplanation
Pollination is the process by which pollen is transferred in plants. It is essential for plant reproduction as it allows for the transfer of male gametes (pollen grains) from the stamen (male reproductive organ) to the stigma (part of the female reproductive organ). This transfer can occur through various means, such as wind, water, or by the help of animals like bees, butterflies, or birds. Pollination plays a crucial role in fertilization and the production of seeds and fruits in plants.Rate this question:

Male part of a flower.
- A.
Stamen
- B.
Stigma
- C.
Pollen
- D.
Pistil
Correct Answer
A. StamenExplanation
The male part of a flower is called the stamen. It is responsible for producing and releasing pollen, which is necessary for the fertilization of the flower. The stamen consists of two main parts, the filament and the anther. The filament is a long, thin structure that supports the anther, where the pollen is produced. The stamen plays a crucial role in the reproductive process of flowering plants by producing and dispersing pollen.Rate this question:

Which of the following is NOT a common agent of pollination?
- A.
Wind
- B.
Insects
- C.
Birds
- D.
Reptiles
Correct Answer
D. ReptilesExplanation
Pollination is crucial for plant reproduction, involving the transfer of pollen for fertilization. Wind, insects, and birds are primary agents in this process. Wind carries pollen, while insects and birds are attracted to flowers for nectar and inadvertently transport pollen. Reptiles, however, lack the necessary adaptations or behaviors to effectively participate in pollination.Rate this question:

Stamen produced sticky powder called _____.
- A.
Pollen
- B.
Style
- C.
Pistil
- D.
Ovule
Correct Answer
A. PollenExplanation
Stamen is the male reproductive organ of a flower, which produces pollen. Pollen is a fine, powdery substance that contains the male gametes of a plant. It is usually sticky in nature and is responsible for fertilizing the female reproductive organs of the flower. Therefore, the correct answer is pollen.Rate this question:

The top of the pistil is called _____.
- A.
Pollen
- B.
Pistil
- C.
Stigma
- D.
Style
Correct Answer
C. StigmaExplanation
The top of the pistil is called the stigma. The stigma is a sticky surface that receives pollen during pollination. It plays a crucial role in the reproduction of flowering plants by capturing and holding onto pollen grains, allowing for fertilization to occur.Rate this question:
