Answer 1

Answer:

Aim: To prove that seed needs oxygen, water and temperature in equal proportions.

Apparatus: A glass slide, a beaker, a thread and bean seeds.

Procedure: Take a glass slide and tie three mature bean seeds at different position. Place the slide in the beaker containing water in such a way that the seed at top is above the water, the middle seed is at the water level and the third seed is submerged in water.

Observation: The top seed does not germinate as it gets oxygen but no water. The middle seed germinates as it gets both oxygen and water. The bottom seeds do not germinate but shows emergence of tiny radical as it gets dissolved oxygen in water in small amount.

Result: A seed need oxygen, water and temperature in equal proportions. In this experiment, the requirement of oxygen is not completely demonstrated.
