Q

39
Q

Define “inflorescence”.

45
Q

What are three ways the design of a flower encourages pollination?

A

The design of a flower encourages pollination through vibrant colors and shapes attracting pollinators, the production of scents and nectar as rewards, and strategic placement of reproductive organs to minimize self-pollination and promote cross-pollination.

46
Q

Describe how a sperm cell in a pollen grain reaches an ovule in the ovary so that fertilization can take place.

A

After the pollen lands on the stigma, a tube grows from the pollen grain through the style to the ovary. Inside the ovary are ovules. Each ovule contains an egg. Sperm cells within the pollen grain move down the pollen tube and into an ovule.

47
Q

What is the difference between sexual reproduction and vegetative reproduction?

A

Sexual propagation involves the floral parts of a plant. Asexual propagation involves taking a part of one parent plant and causing it to regenerate itself into a new plant.

49
