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?
- 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
