Root Shoots and Stems

Food Systems!

In the process of germination:

• The embryo begins growth into a seedling.
• Apical meristems lead the pathway for root and stem growth
• Germination can only begin when temperature, water, air, seed coat treatments have been met*
• Germination is over when the seed leaves have emerged

Aeration

Oxygen is important in the delivery of food to growing plants via cellular respiration.

in compacted soil you risk suffocating the seed.
