Lesson Worksheet: Types of Sexual Reproduction Biology
In this worksheet, we will practice describing different strategies of sexual reproduction and giving examples of organisms that use both sexual and asexual reproduction in their life cycle.
Q1:
Which genus reproduces by conjugation?
- ASclerophrys, Egyptian toad
- BPlasmodium, protist and malaria parasite
- CPolypodium, ornamental fern
- DSynodontis, Nile catfish
- ESpirogyra, a filamentous algae
Q2:
Organisms can reproduce sexually or asexually. Which of the following could threaten the continuity of a population of rabbits but not a population of yeast?
- AMembers of a species are isolated from each other.
- BThere is a disease present within the population.
- CThere is a decrease in nutrient availability.
- DThere are more breeding sites than there are breeding pairs.
- EThere is a sudden change in the environment.
Q3:
What is the advantage of the process shown in the figure?
- AIt allows Spirogyra to maintain genetic uniformity.
- BIt allows Spirogyra to survive when conditions are harsh.
- CIt allows Spirogyra to reproduce rapidly when conditions are favorable.
- DIt allows Spirogyra to increase its surface area for absorption of light.
- EIt allows Spirogyra to clone itself efficiently.
Q4:
The ornamental fern Polypodium, shown in the figure, reproduces by alternation of generations.
Which structure produces female gametes?
- AAntheridium
- BArchegonium
- CSporangium
- DSorus
- ERhizome
Q5:
What are the characteristics of female gametes?
- AThey are produced in small numbers, they are small in size, and they are motile.
- BThey are produced in small numbers, they are large in size, and they have food stores.
- CThey are produced in large numbers, they are small in size, and they are motile.
- DThey are produced in large numbers, they are large in size, and they have food stores.
- EThey are produced in large numbers, they are small in size, and they have food stores.
Q6:
During the life cycle of the ornamental fern (Polypodium), a zygote is produced. What plant form does it develop into?
- AA diploid sporophyte
- BA haploid gametophyte
- CA diploid gametophyte
- DA haploid sporophyte
- EA haploid sporangium
Q7:
Spirogyra is a filamentous algae that grows in fresh water. What reproductive process is happening in the figure?
- ASexual reproduction by scalariform conjugation
- BSexual reproduction by lateral conjugation
- CAsexual reproduction by lateral conjugation
- DAsexual reproduction by budding
- ESexual reproduction by budding
Q8:
Which of the following processes are most crucial for the formation of a human zygote to occur?
- AMitosis and binary fission
- BMeiosis and gamete fusion
- CMeiosis and binary fission
- DBudding and sporogony
- EAlternation of generations
Q9:
The protist Plasmodium is a parasite that lives in two hosts, humans and mosquitoes, as shown in the figure. An alternation of generations can also be seen in its life cycle.
At which stage in the Plasmodium life cycle does fertilization occur?
- AStage 3
- BStage 5
- CStage 4
- DStage 6
- EStage 2
Q10:
During its life cycle, the malarial parasite Plasmodium infects and multiplies inside human red blood cells, as shown in the figure.
What reproductive process occurs inside red blood cells?
- ASexual reproduction to form merozoites and gametocytes
- BAsexual reproduction to form merozoites and gametocytes
- CSexual reproduction to form sporozoites and merozoites
- DAsexual reproduction to form sporozoites and merozoites
- ESexual reproduction to form gametocytes and a zygote
