hey frnds plz ansr This...... spammers plz Stay away from my qstn....​

Answer 1

Explanation:

Experiment to show that optimum temperature is required for seed germination:

1. Take three beakers and label them as 1,2 and 3.

2. Place some cotton wool in each of the three beakers.

3. Wet the cotton wool and place equal no of gram seeds over the cotton wool.

4. Now keep the beaker 1 at an ordinary temperature, beaker 2 in refrigerator and beaker 3 in an oven.

5. Observe the three beakers after 2-3 days.

6. The gram seeds in beaker 1 will germinate while the seeds present in beaker 2 and 3 will not germinate. This shows that requisite temperature is required for the seeds to germinate.......

hope it's helpful

good night

Answer 2

Explanation:

A reasonable temperature is important for germination.

Take two Beakers and name them A and B.

Place some Green gram seeds on cotton wool in each of the two measuring utensils.

Keep measuring utensil A in a cold room and container B in the standard room temperature.

In multi-day or two the seeds in Beaker B will develop while the seeds in beaker A won't hint at any germination or may sprout following a few days yet not to a degree the seeds in Beaker A germinates.

Hence germination can happen in an appropriate temperature.
