6 Most VSAQ’s of Reproduction Chapter in Class 10th Biology (TS/AP)

2 Marks

VSAQ-1 : Give two examples of plants that are propagated by the cutting method.

Plants like Rose and Hibiscus can be easily propagated using the cutting method. This method involves taking a stem or leaf cutting from a parent plant and rooting it to grow a new, identical plant. It’s a popular and effective way to create new plants that retain the desirable traits of the parent plant.

VSAQ-2 : Give any two suggestions to create awareness to stop female foeticide.

  1. Educational Campaigns for Gender Equality:
    Conducting educational campaigns that focus on gender equality and the importance of girls in society. These campaigns can help change societal attitudes and beliefs that contribute to female foeticide.
  2. Community Outreach Programs:
    Implementing community outreach programs that provide support and resources to expectant mothers. Emphasizing the value of both female and male children in these programs. They can also include counseling and assistance, helping to prevent decisions based on gender bias.

VSAQ-3 : Mention two materials you have used to observe Rhizopus on bread mould.

To observe Rhizopus on bread mold, two essential materials used are:

  1. Bread mold (specifically Rhizopus species)
  2. A plain glass slide

VSAQ-4 : What happens if there is no cell division in the cells?

Without cell division, cells would be unable to grow, replicate, or replace damaged cells. This disruption in the cell renewal and repair processes would ultimately lead to the death of the organism. Cell division is crucial for the growth, development, and maintenance of all living organisms.

VSAQ-5 : Write two precautions you take, while observing Rhizopus in the laboratory.

While observing Rhizopus in the laboratory, two important precautions to take are:

  1. Avoid touching the mold with bare hands. In case of accidental contact, wash hands thoroughly to prevent any potential contamination and ensure personal safety.
  2. Avoid frequent opening of the plastic bag containing the bread mold. This helps maintain a controlled environment and prevents disturbances to the growth of the mold.

VSAQ-6 : What are the advantages of sexual reproduction? (OR) Give the importance of sexual reproduction.

The importance of sexual reproduction lies in its numerous advantages:

  1. Origin of New Species:
    Sexual reproduction is pivotal in the evolution and origin of new species. It involves the combination of genetic material from two parents, producing offspring with unique traits and characteristics, which leads to species diversity.
  2. Genetic Diversity:
    Genetic recombination during sexual reproduction results in offspring with varied genetic variations. This genetic diversity is crucial as it enhances the adaptability and survival chances of species in changing environments.
  3. Adaptation to Environment:
    Sexual reproduction facilitates the development of advantageous traits in organisms, enabling them to adapt to their surroundings and effectively cope with environmental challenges.
