Most seeds need water, air and a suitable temperature to germinate. Which of these do most seeds NOT need to begin germinating?

Explanation

1. 01

   Water softens the seed coat and activates enzymes; oxygen is needed for respiration; warmth lets enzymes work.

2. 02

   The seed lives on its stored food at first, so most seeds germinate even in the dark. Light becomes necessary once the seedling starts photosynthesis.
