18 Questions
What is the primary mode of reproduction in single-celled organisms like Amoeba and Paramecium?
Binary fission
What is the process called when Amoeba forms a protective cyst around itself under unfavorable conditions?
Encystment
What is the mode of asexual reproduction in yeast?
Budding
What is the process called when a single-celled organism like Amoeba divides by multiple fission to produce many daughter cells?
Sporulation
Which of the following is an example of asexual reproductive structures in plants and animals?
All of the above
What is the role of mitosis in asexual reproduction of single-celled organisms?
Mitosis is used to produce genetically identical daughter cells
What type of reproduction involves the participation of two parents and the fusion of male and female gametes?
Sexual reproduction
In asexual reproduction, offspring produced by a single parent are likely to be:
Genetically identical to each other and the parent
Which term is used to describe individuals that are morphologically and genetically similar due to asexual reproduction?
Clone
What process is illustrated in Figure 1.2 (b) with Amoeba undergoing division?
Binary fission
Which type of reproduction results in offspring that are exact copies of their parent?
Asexual reproduction
What is responsible for creating genetic variation during reproduction?
Fusion of male and female gametes
In organisms with a haploid parent body, which process is responsible for the production of gametes?
Mitosis
Which type of reproductive division is necessary for a diploid body to produce haploid gametes?
Meiosis
Which type of organisms are more likely to have a diploid parental body according to the text?
Pteridophytes and gymnosperms
What is the significance of meiosis in the life cycle of organisms?
Generating genetic diversity
Which process ensures that a diploid body can produce haploid gametes?
Meiosis
What type of division is responsible for the production of gametes in organisms with a haploid parent?
Mitosis
Study Notes
- Gametes are haploid, even though the parent plant body can be haploid or diploid. A haploid parent produces gametes through mitotic division.
- Meiosis, the reduction division, must occur in organisms with a diploid body to produce haploid gametes.
- Organisms like monera, fungi, algae, and bryophytes have a haploid plant body, while organisms like pteridophytes, gymnosperms, angiosperms, and most animals have a diploid parental body.
- Asexual reproduction is common in single-celled organisms, as well as plants and animals with simple organizations.
- Clones are genetically identical and morphologically similar individuals produced through asexual reproduction.
