Total questions: 40
Worksheet time: 23mins
Many plants can reproduce asexually. Which of these is an example of asexual reproduction?
a potato growing roots
night-blooming cactus flowers
cross-pollination of a tomato
the formation of a pine cone
Which of the following includes the female reproductive structures of a flower?
the stigma
the stamen
the anther
the pistil
Which of the following includes all of the male reproductive structures of a flower?
the pistil
the stigma
the stomata
the stamen
The pistil includes the
filament and style
the filament and anther
the stigma, style, and ovary
the stigma, style, and anther
The stamen includes
the filament and anther
the stigma, style, and ovary
the stigma and style, only
the sepals and petals
A seed that is encapsulated in a brightly colored juicy fruit would be expected to have which dispersal method?
wind
water
animals
all of the above
A primary benefit of sexual reproduction over asexual reproduction is
increased probability that some offspring will have traits that help them survive in changing conditions.
the ability to produce offspring without any genetic disorders.
the decreased probability that some offspring will have genes that are different from the parent, who is already well adapted to the environment.
the reproduction of clones that can produce a new genes through mutation.
A primary benefit of asexual reproduction in plants over sexual reproduction is
plants can reproduce more quickly and take advantage of stable environmental conditions.
plants can become more genetically diverse
plants can better adapt to changes in the environment
plants can produce hybrids that will have traits of both parents
In which situation would sexual reproduction be more beneficial than asexual reproduction?
A pest species in introduced to the area that feeds on that plant.
A new space for growth becomes available.
Conditions are relatively stable and plants are thriving.
A greenhouse keeper is growing carnations and they all need to be a uniform size and color.
What is the difference between seed dispersal and pollination?
Pollination = Fertilization whereas seed dispersal is a means of getting the already fertilized egg (seed) as far away from the parent plant as possible.
Fertilization only happens in seedless plants.
Only flowering seed plants have methods for both pollination and seed dispersal.
Seed plants have seed dispersal whereas seedless plants have pollination.
Plant parts work together as a system for reproduction. Choose the answer that shows the steps of the system in the correct order.
Pollen is releases by the male cone, it lands on the female cone, the egg is fertilized, the seed develops and falls to the ground, a new tree can begin to grow.
Pollen is releases by the male cone, , the egg is fertilized, the seed develops and falls to the ground, pollen lands on the female cone, a new tree can begin to grow.
a new tree can begin to grow, Pollen is releases by the male cone, , the egg is fertilized, the seed develops and falls to the ground, pollen lands on the female cone, .
a new tree can begin to grow, Pollen is releases by the male cone, the seed develops and falls to the ground, the egg is fertilized, pollen lands on the female cone, .
Which plant structures are used in reproduction?
leaves
spores
flowers
wind
cones
Read the evidence and choose the best claim:
-Wind blows pollen.
-Bats can pollinate plants.
-Some plants use cones to reproduce.
-Spores contain egg and male cells.
Pollinators are the best way to pollinate plants.
There are many ways for plants to reproduce.
Water is the quickest way for seeds to move.
Spores use wind to reproduce.
If a plant produces seed that are sticky or bristles, ________________ most likely moves the seed from one place to another.
an animal
the wind
flowers
stay inside
A dandelion produces light, fluffy, seeds that are carried by __________.
stay inside
wind
fruits
water
Study the picture. Match the plant to the correct description of how it reproduces.
This plant uses spores that, if they land in the right place, grow into a heart-shaped structure. This structure grows and releases male and egg cells.
This plant produces cones, In the spring pollen is released from the male cone. If pollen from a male cone lands on a female cone of the same type of tree, the egg will be fertilized.
A plant produces fruit or seeds that float. Which is the most likely way its seeds are moved from one place to another.
wind
water
animals
Flowering plants reproduce...
Sexually
Asexually
Which of the following sentences describes the ways plants spread their seeds? Choose the two that apply.
Bees, attracted by brightly colored flowers, pick up and move seeds to new locations.
Animals, attracted by scent, eat and then disperse seeds in new locations through their droppings.
Seeds are carried away from the parent plant by wind or water.
Seeds are dispersed during pollination.
__________ is the sweet liquid produced by flowers to attract insects and birds.
Nectar
Pollen
Sap
Water
this is the transfer of pollen to the stigma
pollination
pollinator
fertilization
germination
Which type of plant makes up the largest group in the Plantae kingdom?
land plants
water plants
flowering plants
nonflowering plants
It's a new feature to have an open-ended question, so I'm trying it out.
How do flowering plants reproduce? Explain.
