How Much Do You Know About Plant Life Cycle?

1. Pollination is not part of the life cycle process.

True

False

This statement is false because pollination is indeed a crucial part of the life cycle process for many plants. Pollination is the transfer of pollen from the male reproductive organ (stamen) to the female reproductive organ (pistil) of a flower, which leads to fertilization and the production of seeds. This process allows for the continuation of the plant species and is essential for plant reproduction. Therefore, pollination is an integral part of the life cycle process for plants.

2. Seeds must be fertilized before they can germinate.

True

False

Seeds must be fertilized before they can germinate because fertilization is the process of combining male and female reproductive cells to form a zygote. In plants, this process occurs when pollen from the male reproductive organ (stamen) reaches the female reproductive organ (pistil) and fertilizes the ovule. Fertilization provides the necessary genetic material for the seed to develop and grow into a new plant. Without fertilization, the seed would not have the necessary resources to germinate and begin its growth process. Therefore, the statement is true.

3. The four stages of a plant's life cycle are

Germination, respiration, seed dispersal, fertilization

Germination, seed dispersal, fertilization, reproduction

Germination, fertilization, pollination, seed dispersal

Fertilization, dissemination, pollination, fertilization

The correct answer is germination, fertilization, pollination, seed dispersal. This is because germination is the process of a seed sprouting and growing into a seedling. Fertilization is the process of the male pollen uniting with the female ovule to form a seed. Pollination is the transfer of pollen from the male reproductive organ to the female reproductive organ of a plant, which is necessary for fertilization to occur. Seed dispersal is the method by which seeds are spread away from the parent plant, often through wind, water, or animals, to increase the chances of successful germination and plant growth in new locations.

4. Seeds can be dispersed in which of the following ways

Sunlight and water

Wind and animals

Water and gravity

Both b and c

Seeds can be dispersed by wind and animals as well as by water and gravity. Wind can carry seeds over long distances, while animals can eat the seeds and then disperse them through their droppings. Water can transport seeds through rivers and streams, and gravity allows seeds to fall from plants and be dispersed in the immediate vicinity. Therefore, the correct answer is both b and c.
