LS 1-4: Successful Reproduction

What is the main difference between sexual and asexual reproduction?

• Sexual reproduction requires two parent organisms, while asexual reproduction takes place with only one parent organism.

• Both sexual and asexual reproduction are necessary processes for a species to survive in its environment.

• Neither sexual nor asexual reproduction involves the combining of cells from two parent organisms.

• Sexual and asexual reproduction both involve the creation of more individuals of the same species

Male widow birds (Euplectus progne) have very long tail feathers. What evidence would support the claim that these tails are used by the birds to attract mates and lead to reproductive success?

• Only the males of the species have long tail feathers, and the females always have much shorter tail feathers.

• In every generation, the small number of males with the longest tail feathers produce the greatest number of offspring.

• The males with the longest tail feathers are the easier to locate in their habitat than those with shorter tail feathers.

• Even though the wingspan of males does not exceed 15 centimeters, some males have tail feathers 50 centimeters long.

Which of the following plant adaptations allows plants to use animals to transport their seeds to new locations?

• Large leaves

• Strong stems

• Sweet fruit

• Deep roots

What is a difference between self-pollination and cross-pollination?

• Self-pollination leads to the creation of a fruit. Cross-pollination does not.

• During cross-pollination, ovules are carried from one plant to another plant.. During self-pollination the ovules stay on the same plant.

• During cross-pollination the pollen grains are carried from one plant to another plant. During self-pollination the pollen and ovules are from the same plant.

• During cross-pollination, the pollen grains travel from the stigma to the anthers. During self-pollination, the pollen grains travel from the anthers to the stigma.

• There is no difference.
