The fusing of the sperm and ovule is called
fertilization
What type of fruit is an apple?

What is the primary purpose of a flower?
The main purpose of flowers is to attract pollinators to the plant’s pollen so that the reproductive cycle can be continued.
Define “inflorescence”.
the process of flowering; blossoming.
What is fruit?
the fleshy or dry ripened ovary of a flowering plant, enclosing the seed or seeds.
Pollination
fertilization in plants
Fertilization
. Fertilization refers to the fusion of male and female gametes.
self-pollination
when a plant’s own pollen fertilizes its own ovule
cross pollination.
Cross-pollination is the process where pollen is transferred from the male reproductive organs of one plant to the female reproductive organs of another plan
What are three ways the design of a flower encourages pollination?
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.
Describe how a sperm cell in a pollen grain reaches an ovule in the ovary so that fertilization can take place.
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.
What is the difference between sexual reproduction and vegetative reproduction?
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.
Which part of the flower forms the fruit?
The ovary
What is the primary function of a fruit?
spread the seeds and allow the plant to reproduce.
What are the three main parts of a seed?
embryo, endosperm, and seed coaT.
