Topic: Asexual Reproduction Fission Budding Fragmentation
Q1. Which type of asexual reproduction involves the division of one organism into two or more daughter organisms?
- Budding
- Fission
- Fragmentation
- Pollination
Q2.Which organism commonly reproduces by binary fission?
- Amoeba
- Hydra
- Spirogyra
- Rose
Q3. In budding, a new organism develops:
- From a small outgrowth on the parent organism
- Only after fusion of two gametes
- By the breaking of leaves
- From a seed formed after fertilisation
Q4.Spirogyra commonly reproduces through:
- Budding
- Binary fission
- Fragmentation
- Spore formation
Q5.Which of the following correctly matches the organism with its method of asexual reproduction?
- Amoeba - Budding
- Hydra - Budding
- Spirogyra - Binary fission
- Yeast - Fragmentation
Q6.Which statement best distinguishes fragmentation from budding?
- Fragmentation involves pieces of the parent developing into new individuals, while budding begins with an outgrowth
- Fragmentation always requires two parents, while budding requires three
- Both processes always involve fertilisation
- Budding occurs only in plants, while fragmentation occurs only in animals
Short questions
Q1. What is asexual reproduction? State one important feature that distinguishes it from sexual reproduction.
Q2.What is binary fission? Name one organism that reproduces by this method.
Q3.Describe the basic process of budding in an organism such as Hydra.
Q4.What is fragmentation? Name one organism in which this method of reproduction is commonly observed.
Q5. A student observes a green, thread-like organism in a pond. After some time, pieces of the thread appear to develop into complete organisms.
Which type of asexual reproduction does this observation suggest? Explain briefly.
Q6.During a biology activity, a student observes a specimen of Hydra under a microscope and notices a small projection growing from its body.
What reproductive process could this observation represent? Describe what happens to the projection as it develops.
Q1. Explain binary fission in Amoeba. Describe the major stages involved in the formation of new individuals and explain why this method is considered asexual reproduction.
Q2. Explain budding in Hydra. Describe how the bud develops and eventually becomes a new individual. How is this process different from binary fission?
Q3. Compare fission, budding, and fragmentation on the basis of:
How the new individual is formed
The part of the parent involved
One suitable example of an organism
The general sequence of reproduction
Q1. A student observes an organism that first develops a small swelling on its body. The swelling gradually increases in size and later separates from the parent.
a) Which type of asexual reproduction is represented?
b) What is the small swelling called?
Q2. A pond near a village contains long, green, thread-like organisms. During favourable conditions, these organisms break into smaller pieces, and each piece can grow into a complete organism.
a) Identify the reproductive method involved.
b) Why can this method help the organism increase its population?
Q3.Three students make the following observations:
Student A: One unicellular organism divides into two daughter cells.
Student B: A small outgrowth develops on the parent and later separates.
Student C: A long multicellular organism breaks into pieces, and each piece develops into a new organism.
Identify the type of asexual reproduction represented in each observation.
