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, .

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.

There are many ways for plants to reproduce.

Pollinators are the best way to pollinate plants.

Water is the quickest way for seeds to move.

Study the picture. Match the plant to the correct description of how it reproduces.

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.

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.

Fertilization is the process by which an

animal carries pollen between plants

Which of the following sentences describes the ways plants spread their seeds? Choose the two that apply .

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.

Bees, attracted by brightly colored flowers, pick up and move seeds to new locations.

Seeds are dispersed during pollination.
