Because dry seeds have a very low metabolic rate and do not produce much Co2. Germinating seeds produce more Co2.
because dry seeds are dormant and have a very low metabolic rate (as opposed to a germinating seed)
no
Dry seeds have less metabollical rate.So they do not produce significant amount of CO2.
Most seeds are not photosynthetic. So they do not need
(# of seeds germinated/# of seeds sown)*100=% of germination
(# of seeds germinated/# of seeds sown)*100=% of germination
It is eather carbon dioxide light or water.
An end product of CO2 is formed during anaerobic respiration in germinating seeds. This can be determined by an experiment with mercury test tube and germinating seeds.
You are probably referring to carbon dioxide, which plants require to produce carbohydrates for food. However, carbon dioxide also comes from decomposes such as bacteria and fungi. Animals are also useful to plants because they pollinate them, fertilize the soil, and spread their seeds.
Phototropism
Seeds need carbon dioxide, minerals, water and sunlight to grow
The general rule for planting seeds is to put three seeds in the hole, and then prick out the weakest ones, once they have germinated.
