Detailed explanation-1: -Seed by itself does not show the characteristics of living things but under right conditions of temperature, moisture and sunlight, they can grow into a new plant. Hence, they are considered as living things.

Detailed explanation-2: -A seed is the embryo of a new plant and as such is a living thing, but in a dormant state, which requires being buried in soil or other suitable matter to trigger off the renewal process.

Detailed explanation-3: -One method to check for seed viability is the water test. Take the seeds and place them in a container of water. Let the seeds sit for 15 minutes. If the seeds sink, they are still viable; if they float, discard, because they probably will not sprout.

Detailed explanation-4: -All seeds need water, oxygen, and proper temperature in order to germinate. Some seeds require proper light also.

Detailed explanation-5: -Plants are multicellular and autotrophic – they use photosynthesis to produce food using sunlight. Animals are multicellular. They are heterotrophic and rely on other organisms for food.
