It varies somewhat, but seeds generally need a warm moist substrate. So if you sprinkle some radish seeds onto a moist paper towel, put it into a ziplock, and keep it in a warm place, germination is likely to occur. Other seeds have different requirement though-- some seeds need to be partially digested by a bird or mammal before they can sprout. Weird huh?
Air, water and warmth must be present for germination to take place.
Seed germination and seed deterioration can both be affected by microorganisms. Microorganisms can break down the hard outer seed coating. When this happens, the seed must find the right conditions to germinate. If it does not, then the seed will deteriorate and rot.
Variation must exist.
In order for germination of a seed to take place the seed must be viable. Sufficient food must be available for the seed to grow. Water, air, oxygen and appropriate temperature must also be available for the seedâ??s growth.
idk
.There must be at least two parties involved.
poo on bread
zxzcz
1. You must be gay. 2. You must love bum. 3. Must eat poo 4.
All organisms must reproduce.
Germination: Bermudagrass has very good seedling vigor. Under ideal conditions, germination begins within 7 to 10 days. Soil moisture must be maintained during the germination period. Allow 14 to 18 days after the first seedlings emerge for complete germination.
Mutation cannot occur. Apex
