Activity 8.5 NCERT Class 10 Science, How do Organisms Reproduce
Procedure: Activity 8.5 asks us to cut the potato in parts and check if it grows or not.
Observation: Potato parts with at least one bud grows into a plant while potato without any bud does not survive.
Explanation:
The tuber part of potato which we use in the kitchen is a modified stem. It reproduces by vegetative propagation. Farmers sow the potato tuber into the soil which grows into a full plant with multiple tubers.
Buds of potatoes are infact the growing stems. If it is left alone, potato sprout and develop into a full plant. So when we cut a potato into parts, Only those parts which contain at least a bud grows.
Inference/Conclusion: We call this mode of reproduction vegetative propagation. Vegetative reproduction is a common method which we use in plants like potato, rose, mango, etc.
