Lesson Worksheet: Asexual Reproduction in Plants Science

In this worksheet, we will practice describing asexual reproduction in plants, and outlining methods of natural and artificial vegetative propagation.

Q1:

Asexual reproduction in plants will produce offspring that are genetically identical to the parent. What is a disadvantage of this?

  • AIt always produces deformed or diseased plants.
  • BIt produces plants that only have half the genetic material of the parent (they are haploid).
  • CIt reduces the lifespan of the parent plant.
  • DIt reduces the genetic variation of a population.

Q2:

Which of the following is true about asexual reproduction in plants?

  • AAsexual reproduction only needs one parent plant.
  • BPlants can only use asexual reproduction if the soil conditions are right.
  • CAsexual reproduction will make plants that are genetically diverse.
  • DAsexual reproduction in plants takes much more time than sexual reproduction.

Q3:

The diagram shows the basic outline of the process of producing plants by tissue culture.

What is taken from the parent plant?

  • ACells from the flower
  • BTissue from the stem
  • CHormones from the leaf

What are the products?

  • APlants that are identical to the parent plant
  • BGametes that can be fertilized to grow into plants
  • CPlants that are genetically unique

Q4:

A plant can produce new plants from its leaves, stem, and roots using asexual reproduction. What term is given to this method of reproduction?

  • AMeiosis
  • BGametogenesis
  • CStem cell cloning
  • DPollination
  • EVegetative propagation

Q5:

Tubers, such as potatoes (pictured), can reproduce using asexual reproduction. Which of the following statements best explains how?

Fresh organic potatoes in the field-edited
  • AThe tuber forms many spores, which are expelled from the tuber and repeatedly divide to form new organisms.
  • BBuds grow on the surface of the tuber, which grow into a new, genetically identical plant.
  • CThe tuber forms horizontal stems along the ground, and plantlets form along the stem.
  • DThe tuber produces gametes, which combine with the gametes of other tubers to form a new plant.

Q6:

In which part of a plant will vegetative propagation not occur?

  • AFlowers
  • BStems
  • CRoots
  • DLeaves
  • EBuds

Q7:

A plant can reproduce naturally using vegetative propagation or artificially with the help of humans. Which of the following is a method of artificial vegetative propagation?

  • ATaking a cutting
  • BSporogony
  • CGrowing rhizomes
  • DCross-pollination

Q8:

Plants can be reproduced by a process called grafting. The diagram gives a basic outline of this process.

Which number indicates the stock?

Which number indicates the scion?

Q9:

Plants can be reproduced asexually by a process called grafting. The diagram gives a basic outline of this process. Which of the following is correct about the plant produced by grafting?

  • AAny seeds produced will be part of the stock.
  • BAny roots produced will be part of the scion.
  • CAny fruit produced will be part of the scion.
  • DThe scion and the stock will produce gametes to create a new species of plant.

Q10:

The drawings show the basic outline of a method of artificial vegetative propagation. What method is shown here?

  • AGrafting
  • BTaking a cutting
  • CSporogony
  • DTissue culture
