Sexual Reproduction in Flowers

Click on the flashcard to see the answer



What does sexual reproduction in flowers involve?

It involves the formation and fusion of male and female gametes, leading to seed production.

Where does fertilization occur in a flower?

Fertilization occurs inside the ovule.

What is syngamy?

Syngamy is another term for fertilization, the fusion of male and female gametes.

What is the initial result of fertilization in flowers?

The initial result of fertilization is the formation of a zygote.

Describe the transformation from zygote to seed.

After fertilization, the zygote divides to form an embryo, and the ovule develops into a seed.

What forms from the ovary after fertilization?

The ovary grows into a fruit following fertilization.

Which flower parts may shrivel and fall off after fertilization?

Petals, sepals, stamens, style, and stigma may shrivel and fall off.

What triggers the germination process in seeds?

The germination process is triggered by imbibition, the uptake of water by seeds.

How does germination begin?

Germination begins when the seed absorbs water, causing it to swell and activate enzymes.

What is the function of the seed coat during germination?

The seed coat protects the seed as it swells and begins to grow.

What does the embryo develop into?

The embryo develops into a new plant.

What occurs to the zygote after it is formed?

The zygote undergoes multiple divisions to form an embryo.

How does the ovule transform post-fertilization?

The ovule transforms into a seed post-fertilization.

Name the main reproductive parts involved in flower reproduction.

The main parts are the pistil (female) and stamen (male).

What changes occur in the ovary post-fertilization?

The ovary transforms into a fruit.

1. What does sexual reproduction in flowers involve?

It involves the formation and fusion of male and female gametes, leading to seed production.

It involves photosynthesis and seedless expansion.

It involves asexual budding and root development.

It involves the breaking of flower parts for reproduction.

2. Where does fertilization occur in a flower?

Fertilization occurs inside the ovule.

Fertilization occurs on the stamen.

Fertilization happens in the petals.

Fertilization occurs at the flower stigma.

3. What is syngamy?

Syngamy is the process of pollen formation.

Syngamy occurs when sepals develop.

Syngamy is another term for fertilization, the fusion of male and female gametes.

Syngamy is the growth of the flower ovary into a fruit.

4. What is the initial result of fertilization in flowers?

The petals change color immediately.

The initial result of fertilization is the formation of a zygote.

The ovule becomes dormant indefinitely.

The stamen develops into an embryo.

5. Describe the transformation from zygote to seed.

The zygote instantly enlarges to form a fruit.

The seed directly becomes the embryo without dividing.

After fertilization, the zygote divides to form an embryo, and the ovule develops into a seed.

The zygote splits into multiple seeds immediately.

6. What forms from the ovary after fertilization?

The ovary grows into a sepal after fertilization.

The ovary grows into a fruit following fertilization.

The ovary shrivels to form a seedling.

The ovary disintegrates, leaving only the stamen.

7. Which flower parts may shrivel and fall off after fertilization?

Ovaries, sepals, roots, and stems.

Petals, sepals, stamens, style, and stigma may shrivel and fall off.

Leaves, introduction petals, and seeds.

Fruit, core seeds, and root tips.

8. What triggers the germination process in seeds?

The process is triggered by sunlight exposure.

The germination process is triggered by imbibition, the uptake of water by seeds.

It is triggered directly by the presence of pollen.

The germination occurs by drying of the seeds.

9. How does germination begin?

Germination begins when the seed absorbs water, causing it to swell and activate enzymes.

Germination starts when the seed breaks open directly.

It starts by scattering the seed over dry soil.

Germination begins from the outer petals with no water needed.

10. What is the function of the seed coat during germination?

The seed coat helps the seed fly in the wind.

The seed coat protects the seed as it swells and begins to grow.

It consumes the surrounding soil nutrients.

The seed coat absorbs sunlight for germination.

11. What does the embryo develop into?

The embryo develops into a new plant.

It turns into a single flower petal.

The embryo dissolves after germination.

It develops into only the seed coat of future plants.

12. What occurs to the zygote after it is formed?

The zygote hardens and forms a stem directly.

The zygote undergoes multiple divisions to form an embryo.

It changes into multiple sepals directly.

The zygote acts as a single stamen.

13. How does the ovule transform post-fertilization?

The ovule disintegrates in all flowers.

The ovule transforms into a seed post-fertilization.

It becomes a mature leaf.

The ovule does not change.

14. Name the main reproductive parts involved in flower reproduction.

The main parts are the pistil (female) and stamen (male).

The parts are roots and branches.

The anthers and the ovary trunk are the main parts.

The corolla and calyx serve as main reproductive parts.

15. What changes occur in the ovary post-fertilization?

The ovary transforms into a fruit.

It changes into a sepals storage unit.

The ovary turns yellow and brown during development.

It does not undergo any transformation.
