I am a flower that produces nectar. What is the function of the nectar?

To attract animals to disperse the fruits

I have large petals and are usually brightly colored. How am I pollinated?

Animals, birds and insects are all possible pollinators

A plant that cross-pollinates...

reproduces with another plant of the same species

reproduces within it's own flower

reproduces with more than one other plant of the same species

reproduces with another species of plant

the female part of the flower that becomes a fruit

the sticky part of the flower that accepts the pollen

the male part of the flower that produces pollen

another name for the stem of the plant

Fertilization is the process by which an

animal carries pollen between plants

pollen is carried away from a flower by a pollinator

Choose the correct order of events in flower fertilization

Pollen transfers to stigma, pollen tube is produced, sperm fertilizes egg, seed develops

Sperm fertilizes egg, pollen tube is produced, seed develops, pollen transfers to stigma

Seed develops, pollen tube is produced, pollen transfers to stigma, seed develops into a new plant

Sperm moves down pollen tube, sperm fertilizes egg, pollen transfers to stigma, seed develops

How is having seeds surrounded by yummy fruit an advantage for plants?

Animals eat the fruit and disperse seeds at other locations

It helps pollen stick to the stigma

It attracts insects for pollination

What advantage is cross pollination in plants over self pollination?

It allows for more genetic diversity within the same species

Cross pollination allows bees to feed on nectar

Pollen collected from other flowers survive longer

The flower does not need pollinators in cross pollination

Why is there so much concern regarding the decrease of the honey bee population?

Bees are estimated to pollinate one third of our food crops, so there might be less food world-wide

Spiders will start to die without bees as a food source

No worries! The honey supply will increase without bees to eat it

There will be no more roses for flower shops to sell

What is the difference between pollination and fertilization in a flower?

pollination is getting the pollen to the stigma, fertilization occurs when sperm from pollen enters the ovule (egg)

fertilization is getting the pollen to the stigma, pollination is when sperm from pollen joins with the ovule (egg)

fertilization never occurs in plants, only pollination can

pollination occurs only in mammals, fertilization occurs only in plants
