Seeds do not carry out photosynthesis to make food as they don’t have green leaves yet.
|
|
|
Seeds have seed leaves which store nutrients to carry out photosynthesis.

Detailed explanation-1: -Sunlight is not necessary for seeds to germinate. A seed put under the soil does not get sunlight, but it still germinates. Sunlight is required after the sprouting of seed, for the preparation of by the process of photosynthesis.
Detailed explanation-2: -Small seeded plants that form soil seed banks for instance, are expected to germinate only in the presence of light, as a mechanism to avoid germinating too deep in the soil where they would deplete seed nutrients before reaching light for photosynthesis (Pons 2000).
Detailed explanation-3: -The most appropriate reason for taking germinating seeds in the experiment to show that carbon dioxide is produced during respiration, is : (1) germinating seeds create high temperature. (2) germinating seeds are easy to handle. (3) germinating seeds are living things.
