Question

Summarize the experiment results below to explain what conditions are required for seed germination:

Answer 1

Explanation:

Oxygen,moist and warm conditions are necessary for the germination of plants.

For further development, plants need sunlight for photosynthesis. Initially,the germinated seeds will get enough nutrients from the cotyledons.But it will dry up soon.

So the plants in beaker E will not grow further after all the nutrients drain up.

So the best condition for the plant growth is in beaker D.

Answer 2

Germination in plants.

Step by step explanation:

• The experiment is showing growth of plants in different conditions.
• In test tube A, the growth of plant is not seen at temperature 4 degree Celsius even if there is presence of enough light oxygen and moist soil.
• In test tube B, there is no growth of plant when the soil is dry, presence of oxygen and warm temperature.
• No plant grows when there is absence of oxygen. the oxygen is absorbed with the help of Pyrogallol. This is seen in test tube C
• Plants have grown fully when there is presence of oxygen, moist soil and warm temperature.. this is seen in test tube D
• The plants in test tube E will not grow because of lack of light. As light is the main source for photosynthesis even in favourable conditions.

Hence for a proper growth of plant there should be presence of light, oxygen, warm temperature and moist soil. Test tube D is ideal for the growth of plant.
