1.
You have learned in MODULE 3 that animals reproduce in differ
ent ways - sexual or asexual. Is it also true with plants?
Correct Answer
B. YES
Explanation
Yes, it is true that plants can reproduce in both sexual and asexual ways. Sexual reproduction in plants involves the fusion of male and female gametes, resulting in the formation of a zygote. Asexual reproduction in plants can occur through various methods such as vegetative propagation, where new plants are produced from stems, leaves, or roots of the parent plant.
2.
Do all plants reproduce the same way or they also use different strategies to perpetuate their species?
Correct Answer
B. They use different types of reproduction
Explanation
Plants do not all reproduce in the same way. While some plants reproduce through sexual reproduction, others use asexual reproduction. Sexual reproduction involves the fusion of male and female gametes, resulting in offspring with genetic variation. Asexual reproduction, on the other hand, involves the production of offspring without the involvement of gametes, resulting in genetically identical offspring. Therefore, plants have different strategies to perpetuate their species, utilizing both sexual and asexual reproduction methods.
3.
What type of reproduction do most plants use?
Correct Answer
D. Depends on the plant type
Explanation
Most plants have the ability to reproduce both sexually and asexually. Some plants reproduce sexually through the fusion of male and female gametes, while others can reproduce asexually through methods such as vegetative propagation or spore formation. The type of reproduction that a plant uses depends on various factors such as its species, environmental conditions, and availability of pollinators. Therefore, it cannot be generalized that all plants use a specific type of reproduction, and it varies depending on the plant type.
4.
What plant part is responsible for reproduction in most flowering plants?
Correct Answer
B. Flowers
Explanation
Flowers are responsible for reproduction in most flowering plants. They contain the reproductive organs, including the male stamens that produce pollen and the female pistils that contain the ovules. Flowers attract pollinators such as bees, butterflies, and birds, which transfer pollen from the male to the female parts of the flower, enabling fertilization and the production of seeds. Therefore, flowers play a crucial role in the reproductive cycle of flowering plants.
5.
Which of the following helps flowering plants in their reproduction? You may check more than one box.
Correct Answer(s)
A. Insects
B. People
D. Wind
Explanation
Insects, people, and wind all play a role in the reproduction of flowering plants. Insects, such as bees, butterflies, and beetles, help in pollination by transferring pollen from the male parts of a flower to the female parts of another flower. People can also aid in pollination by intentionally transferring pollen between flowers. Wind plays a crucial role in plants that rely on wind pollination, as it carries pollen grains from the male flowers to the female flowers. Soil, on the other hand, does not directly assist in the reproduction of flowering plants.
6.
How does pollination help plants?
Correct Answer
B. Its a means to reproduce.
Explanation
Pollination is the process by which pollen is transferred from the male reproductive organs of a flower to the female reproductive organs, resulting in fertilization and the production of seeds. This process is crucial for the reproduction of plants as it allows for the transfer of genetic material and the creation of offspring. By pollinating, plants ensure their survival and continuation of their species. Therefore, pollination is a means for plants to reproduce.
7.
What is the result of pollination and fertilization?
Correct Answer
fruit
Explanation
Pollination is the process of transferring pollen from the male reproductive organ to the female reproductive organ of a flower, resulting in fertilization. Fertilization occurs when the male gamete (sperm) fuses with the female gamete (egg) to form a zygote. The zygote develops into a seed, and the ovary of the flower develops into a fruit. Therefore, the result of pollination and fertilization is the formation of a fruit.
8.
Why are fruits important to plants?
Correct Answer
they protect the seeds
Explanation
Fruits are important to plants because they play a crucial role in seed dispersal and protection. By enclosing the seeds within a protective covering, such as a fleshy fruit or a hard shell, plants ensure that the seeds are not easily damaged or eaten by animals. This increases the chances of successful seed germination and the establishment of new plants. Additionally, fruits attract animals through their bright colors and enticing aromas, which aids in the dispersal of seeds over larger distances as animals consume the fruits and then excrete the seeds elsewhere.
