Test Your Knowledge Over Plant Reproduction
This quiz is on the topic of plant reproduction. It is revision for the IGCSE exams in the coming month.
Questions and Answers
- 1.
What is the germination?
- A.
Growth of plants
- B.
The flower
- C.
Growth of the seeds
- D.
Process of seed dispersal
Correct Answer
C. Growth of the seedsExplanation
Germination refers to the process in which a seed begins to grow and develop into a new plant. It involves the activation of the seed, absorption of water, and the emergence of a root and shoot. This process leads to the growth of the seeds into seedlings, which eventually develop into mature plants. Therefore, "Growth of the seeds" is the correct answer as it accurately describes germination.Rate this question:

Which is the female part of the flower?
- A.
Filament
- B.
Carpel
- C.
Anther
- D.
Style
Correct Answer
B. CarpelExplanation
The carpel is the female part of the flower. It is responsible for producing and protecting the female reproductive cells, known as eggs or ovules. The carpel consists of three main parts: the stigma, which receives pollen; the style, which connects the stigma to the ovary; and the ovary, which contains the ovules. Together, these structures play a crucial role in the fertilization and development of seeds in flowering plants.Rate this question:

What is the male part of the flower?
- A.
Style
- B.
Stigma
- C.
Sepal
- D.
Stamen
Correct Answer
D. StamenExplanation
The male part of the flower is called the stamen. The stamen is composed of two main parts: the filament and the anther. The filament is a long, slender structure that supports the anther, which contains the pollen grains. The stamen is responsible for producing and releasing the pollen, which is necessary for the fertilization of the flower.Rate this question:

What is pollination?
- A.
The transfer of male gametes to female parts
- B.
Fusion of male and female gametes
- C.
Growth of an embryo
- D.
Process of seed dispersal.
Correct Answer
A. The transfer of male gametes to female partsExplanation
Pollination refers to the transfer of male gametes (pollen) from the male reproductive organ (anther) to the female reproductive organ (stigma) of a flower. This transfer is essential for the fertilization of the ovules, leading to the formation of seeds. It is through pollination that the fusion of male and female gametes occurs, enabling the reproduction of flowering plants.Rate this question:

is the ovule that contains the embryo of the plant.
Correct Answer
SeedExplanation
A seed is the ovule that contains the embryo of the plant. It is the structure that carries the genetic information needed for the development of a new plant. Inside the seed, the embryo is protected by a seed coat, which provides the necessary conditions for the embryo to remain dormant until it is ready to germinate. When the seed is planted in the soil and provided with the right conditions of moisture, warmth, and oxygen, the embryo starts to grow and develop into a new plant. Therefore, the correct answer is seed.Rate this question:

Correct Answer
Sexual reproductionExplanation
When two parents, one male and one female, fuse, it is called sexual reproduction. This process involves the fusion of gametes (reproductive cells) from the male and female parents to form a new individual with a unique combination of genetic traits. Sexual reproduction allows for genetic diversity and variation in offspring, as each parent contributes half of their genetic material to the offspring. This is in contrast to asexual reproduction, where offspring are produced from a single parent and are genetically identical to that parent.Rate this question:

Correct Answer
Stamen, anther, filamentExplanation
The male part of the flower is called the stamen. It consists of two main parts: the anther and the filament. The anther is the part of the stamen that produces and contains pollen, which is necessary for the process of fertilization. The filament is the long, slender stalk that supports the anther and holds it in position for pollination to occur. Together, the stamen, anther, and filament play a crucial role in the reproductive process of flowering plants.Rate this question:
