Reproduction in plants interactive activity for grade 7 | Live ... - Free Printable

Let’s go step by step to solve each part of the worksheet.

Part I: Choose the correct option

We are given 4 definitions and need to fill in the blank with the right term.

1. “Process by which a single parent body produces young ones.”
→ This is called asexual reproduction. Only one parent is involved, no gametes (sex cells) needed.

2. “In this method, any part of the plant other than the reproductive part can give rise to a new plant.”
→ This is vegetative propagation. For example, a potato tuber or a leaf cutting can grow into a new plant.

3. “Process by which both the parent bodies male and female take part in producing new ones.”
→ This is sexual reproduction. It needs two parents — male and female — to combine their genetic material.

4. “The process by which living beings produce young ones.”
→ This is simply reproduction. It’s the general term for making offspring.

Part II: Select the correct option (based on diagrams)

There are three diagrams shown. We need to identify what type of reproduction each shows.

First diagram (top):
Shows a cell growing a small bump that becomes a new individual and detaches.
→ This is budding, common in yeast and hydra. A form of asexual reproduction.

Second diagram (middle):
Shows a filamentous green alga (like Spirogyra) breaking into pieces, each piece growing into a new organism.
→ This is fragmentation. The parent breaks apart, and each fragment grows into a new individual.

Third diagram (bottom):
Shows a fungus-like structure with spores being released from a sporangium.
→ This is spore formation. Spores are tiny reproductive units that can grow into new organisms under good conditions. Common in fungi, ferns, and some algae.
