Worked practice questions

Producing industrial chemicals such as alcohol from sugar molasses using transgenic yeast belongs to which branch of biotechnology?

  1. White biotechnology
  2. Reproductive cloning
  3. DNA fingerprinting
  4. Organ transplantation
Show answer and solution

Correct answer: A. White biotechnology

1. Making industrial chemicals through cheaper biological processes is industrial biotechnology. 2. This is called white biotechnology, for example alcohol from molasses using transgenic yeast. 3. Cloning makes organisms, DNA fingerprinting establishes identity and transplantation replaces organs; none describe industrial chemical production. _Source: Balbharati (Maharashtra Board) Class 10 Science & Technology Part 2, Ch 8 "Cell Biology and Biotechnology", p.104_

The absorption or destruction of toxic chemicals and pollutants with the help of plants and microorganisms is called:

  1. Vaccination
  2. Bioremediation
  3. Tissue culture
  4. Apiculture
Show answer and solution

Correct answer: B. Bioremediation

1. Cleaning pollutants using living organisms is the defining idea here. 2. This process is called bioremediation, and when only plants are used it is phyto-remediation. 3. Vaccination builds immunity, tissue culture grows plant clones and apiculture is bee keeping; none clean pollutants. _Source: Balbharati (Maharashtra Board) Class 10 Science & Technology Part 2, Ch 8 "Cell Biology and Biotechnology", p.105_

When only plants are used to absorb or destroy pollutants from soil, the technique is specifically called:

  1. Pasteurisation
  2. Pisciculture
  3. Phyto-remediation
  4. Vermiculture
Show answer and solution

Correct answer: C. Phyto-remediation

1. Bioremediation uses plants and microorganisms together. 2. When plants alone do the cleaning, the technique is named phyto-remediation. 3. Pisciculture is fish farming, pasteurisation heats milk and vermiculture rears earthworms, so they do not fit. _Source: Balbharati (Maharashtra Board) Class 10 Science & Technology Part 2, Ch 8 "Cell Biology and Biotechnology", p.105_
