Questions and Answers

What is reproduction in organisms?

  • The process by which organisms obtain energy from the environment
  • The process by which organisms grow and mature
  • The process by which organisms produce their offspring similar to themselves (correct)
  • The process by which organisms obtain nutrients from the soil

    • What are the offspring produced in asexual reproduction referred to as?

  • Variants
  • Hybrids
  • Mutants
  • Clones (correct)

    • What is a characteristic of asexual reproduction?

  • Results in genetically diverse offspring
  • Involves only mitosis (correct)
  • Occurs at a slower rate than sexual reproduction
  • Involves fusion of gametes

    Match the mode of asexual reproduction with its description:

    <p>Binary fission = The parent body divides into two equal halves and each half grows into an adult Budding = Small bud is produced due to cell division at one particular site, which remains attached initially to the parent cell and eventually gets separated and matures into a new individual Parthenogenesis = Development of an embryo from an unfertilized egg Fragmentation = Breaking of the body into several pieces, each of which can grow into a new individual</p> Signup and view all the answers
