Flower part to Fruit in Reproduction in Plants – Class 7 Science Experiment

Chapter Name: Reproduction in Plants

Activity Name: Flower part to Fruit in Reproduction in Plants

Activity Description:

Required Items:

1. Datura plant (pistil and fruit)
2. Cucumber
3. Bhendi (Ladies finger/Okra)
4. Cotton
5. Beans

Step by Step Procedure:

1. Collect a pistil and fruit from a datura plant.
2. Carefully cut transverse sections of both the ovary of the pistil and the fruit.
3. Use a hand lens to observe the internal structures of both the ovary and fruit sections.
4. Repeat the above steps for cucumber, bhendi, cotton, and beans.

Experiment Observations:

1. Observe the internal structure of the ovary and fruit of each plant species.
2. Note down any similarities between the ovary and fruit sections.

Precautions:

1. Handle the plant materials with care to avoid damaging the delicate structures.
2. Use a sharp cutting tool under adult supervision.
3. Ensure proper disposal of plant materials after the experiment.

Lesson Learnt from Experiment:

Through this experiment, students will likely discover that there are similarities between the ovary and fruit of the same plant species. It is reasonable to conclude that the ovary develops into a fruit, and the ovules within the ovary develop into seeds. These seeds further give rise to new plants through the process of germination and growth.
