Study Notes
Plant Development
- Plant development is a combination of growth and differentiation.
- Mature plant development from a zygote follows a precise sequence of events.
- This process creates a complex body with roots, leaves, branches, flowers, fruits, and seeds.
- Plants eventually die.
Seed Germination
- Seed germination is the initial stage of plant growth.
- Germination occurs when environmental conditions are favorable for growth.
- Seeds do not germinate if conditions are unfavorable.
- Unfavorable conditions induce a period of suspended growth or dormancy in seeds.
- Seeds resume growth when favorable conditions return.
