Important Questions Test: Reproduction in Plants - Class 7 MCQ

When parts of plants like cacti get detached, they can grow into new plants. So, plants like cacti produce new plants when their parts get detached.

• Even though it might seem like a lot of seeds growing in one place could be good, it's actually not.
• If all the seeds from a plant grew in the same spot, they would have to compete for sunlight, water, minerals, and space.
• This competition would make it hard for the seeds to grow into healthy plants.
• So, it's better for seeds to spread out and grow in different places to avoid this tough competition!

• Spores are microscopic reproductive units of fungi.
• They are carried by air currents and can land on suitable surfaces, like bread.
• Once they land in a favorable environment, they can germinate and grow into new fungal colonies.
• This process is how fungi reproduce and spread, making spores essential for their lifecycle.

- Correct Answer: C: Fragmentation
- Concept: Fragmentation is a type of asexual reproduction where an organism breaks into fragments. Each fragment can grow into a new, independent organism.
- Examples: Common in organisms like starfish, sponges, and some types of fungi.
- Process:
- The organism divides into parts.
- Each part regenerates the missing parts to form a complete organism.
- Benefits: Allows rapid population increase without the need for a mate.
