D Correct answer
Explanation
Sprouting time of seeds may vary according to the temperature and humidity of the weather. Some seeds are hard to germinate when the weather is hot. Sometimes the temperature is just too high for that seed, sometimes the soil dries out too fast. Some varieties of some crops have better germination at high temperatures than others.

So, the correct answer is 'Both A and B'.

State whether the following statements are true or false.
Seedlings grown for a few days in the dark often have lesser fresh weight and greater dry weight than those kept in light for a comparable period.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

For the development of any seedling or plants, both light and dark phases are required for proper growth. The seedlings that are growing requires light as the carbon sources in them and the other nutrients are present in its complete amount but when they are placed in the darkness they are unable to perform certain functions so there is less production of nutrients resulting in lower fresh weight. Thus, the light phase is the phase on which growth of the plant is dependent upon. 

So, the correct statement is 'False'.
