Melon is an example of ___________.
Correct Answer
C. Creeping plant
Explanation
Melon is classified as a creeping plant because it has long, trailing stems that spread along the ground. Creeping plants typically have a low, spreading growth habit and often produce runners or vines that allow them to spread and cover a larger area. Melons, such as watermelons and cantaloupes, have a vining growth habit and produce long, trailing stems that creep along the soil surface. This allows the plant to take up more space and access sunlight, nutrients, and water from a larger area. Therefore, melon is an example of a creeping plant.

20.
When the fruit is ripe, the seeds are ready to be scattered. Spreading of seeds is
called ___________.
Correct Answer
B. Dispersal
Explanation
When a fruit is ripe, it means that the seeds inside it have developed fully and are ready to be spread or dispersed away from the parent plant. This dispersal is essential for the survival and propagation of plant species. Pollination refers to the transfer of pollen from the male to the female reproductive organs of a plant, which is different from seed dispersal. Germination is the process by which a seed begins to grow into a new plant, and fertilization is the fusion of male and female gametes to form a zygote. Therefore, the correct answer is dispersal.
21.
This part of a flower contains the OVULES.
Correct Answer
A. Ovary

The correct answer is ovary. The ovary is the part of the flower that contains the ovules. The ovules are the structures that develop into seeds after fertilization. The ovary is located at the base of the flower and is typically swollen and enlarged. It plays a crucial role in the reproduction of flowering plants by protecting and nourishing the ovules.
22.
A plant’s _________ help it to reproduce.
Correct Answer
C. Flowers
Explanation
Flowers in plants play a crucial role in reproduction. They contain the reproductive organs, including the male stamen and the female pistil. The stamen produces pollen, which is transferred to the pistil for fertilization. Flowers also attract pollinators like bees, butterflies, and birds through their bright colors and sweet fragrances, aiding in pollination. Once fertilization occurs, flowers develop seeds that can be dispersed to new locations for germination and growth. Therefore, flowers are essential for the reproduction of plants.
23.
