Question

What happens when seeds are placed in water?

• A. Bad quality seeds float on water and good quality seeds settle at the bottom.
• B. Bad quality seeds settle at the bottom and good quality seeds float on water.
• C. Both good quality and bad quality seeds settle at the bottom.
• D. Both good quality and bad quality seeds float on water.

Answer 1

The correct option is A

Bad quality seeds float on water and good quality seeds settle at the bottom.

$\bullet$ Good quality seeds settle down at the bottom because they are well filled, heavy and have more density due to the presence of starch or carbohydrates required for germination.
$\bullet$ Bad quality seeds float at the top because they are less dense as they are mostly hollow and have a lower density of starch.
