Pollination/Cell Cycle Quiz 2024

How do insects help a plant reproduce?

• Insects help the pollen tubes grow from the style of the plant.

• Insects help move pollen from the anthers to the stigma.

• Insects help the stigma produce pollen to be moved to the anthers.

• Insects feed on plant nectar and use it to make honey.

What must happen before mitosis to ensure that each new cell will be an exact copy of the parent cell?

• Telophase

• Mitochondria must create ATP

• Chromosomes are copied.

• Cytokinesis

In self pollination, pollen that is produced in the ​ (a)   of the plant is transferred to the ​ (b)   of the same plant. ​ (c)   grow from the pollen grain and carry ​ (d)   to the ​ (e)  

• anthers
• stigma
• Pollen tubes
• sperm cells
• ovules.
• egg cells
• style

In ​ (a)   the pollen is transferred from the ​ (b)   to the ​ (c)   of the same plant.

• self pollination
• anther
• stigma
• cross pollination
• pollen tube
• ovary

During​ (a)   the pollen is transferred from the ​ (b)   of one plant to the ​ (c)   of another plant.

• cross pollination
• anther
• stigma
• self pollination
• filament
• ovules

In some plants, the pistil doesn't form until a few days after the stamens do. How might this keep a plant from self pollinating?

• Without the pistil there is no anther to produce pollen.

• Without the pistil there is no nectar for insects to eat.

• Without the pistil there is no stigma to receive the pollen.

• Without the pistil there are no petals to attract insects.

When does the cell cycle begin?

• When the cell divides and makes new cells.

• When the new cells are formed.

• When the cell uses energy.

• When the cell takes in oxygen.

• Petal

• Sepal

• Flower

• Cell Wall

When does the cell cycle end?

• When the cell divides to make new cells.

• When the new cells are formed.

• When the cell uses energy

• When the cell takes in oxygen

Programmed cell death, the process that causes cells to self destruct.

• Mitosis

• Meiosis

• Apoptosis

• Phagocytosis
