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.
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.
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.
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
A plant can produce new plants from its leaves, stem, and roots using asexual reproduction. What term is given to this method of reproduction?
- CStem cell cloning
- EVegetative propagation
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.
In which part of a plant will vegetative propagation not occur?
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
- CGrowing rhizomes
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?
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.
The drawings show the basic outline of a method of artificial vegetative propagation. What method is shown here?
- BTaking a cutting
- DTissue culture
