What part of the flower will turn into a seed?
stigma
anther
ovule (egg)
filament
Brightly colored parts of flowers that attract insects.
petals
pistils

The transfer of pollen to the female part of the flower.
seed disperal
pollination
germination
regeneration
The ovary, style, and the stigma make up the female part of a plant called the
stamen
petals
stem
pistil
After fertilization what does the flower's ovary develop into?
Fruit
Bud
Seed
Flower
My flowers are not sweet-scented and I do not produce nectar. How am I likely dispersed?
By wind
By insects
By hummingbirds
By exploding
I am a flower that produces nectar. What is the function of the nectar?
To provide food for the flower
To attract pollinators
To attract animals to disperse the fruits
To produce perfumes for Man
Pollination can occur within the same flower.
True
False
Pollination can occur between flowers of the same plant.
True
False
Pollination can occur between flowers of the different plants of the same species.
True
False
I have large petals and are usually brightly colored. How am I pollinated?
Only by animals
Only by birds
Only by insects
Animals, birds and insects are all possible pollinators
I am a flower with a long and feathery stigma. This would most likely be an advantage for pollination by
wind
waves
ants
explosive action
A plant that cross-pollinates...
reproduces within it's own flower
reproduces with another plant of the same species
reproduces with more than one other plant of the same species
reproduces with another species of plant
What is an ovary?
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
What does a plant ovule (egg) become when it is fertilized?
a seed
a sprout
a fruit
it stays an ovule
What must be made by the pollen grain so sperm can reach the egg for fertilization?
Pistil
Pollen tube
Pollen
Anther
Fertilization is the process by which an
embryo grows into a new plant
egg and sperm combine
animal carries pollen between plants
pollen is carried away from a flower by a pollinator
The pollen is produced by this male reproductive part of the flower
Anther
Pistil
Sepals
Petals
Choose the correct order of events in flower fertilization
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
Pollen transfers to stigma, pollen tube is produced, sperm fertilizes egg, seed develops
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?
It is food for the plant
It helps pollen stick to the stigma
It attracts insects for pollination
Animals eat the fruit and disperse seeds at other locations
The comet orchid is scentless during the day but becomes fragrant at night. Which would most likely be the pollinator of this plant?
Butterfly
Water
Moth
Honeybee
What advantage is cross pollination in plants over self pollination?
Cross pollination allows bees to feed on nectar
Pollen collected from other flowers survive longer
The flower does not need pollinators in cross pollination
It allows for more genetic diversity within the same species
Why is there so much concern regarding the decrease of the honey bee population?
Spiders will start to die without bees as a food source
Bees are estimated to pollinate one third of our food crops, so there might be less food world-wide
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
