Plant Development

The process of a mature plant developing from a fertilized egg.

Seed Germination

The first stage of plant development, taking place when environmental conditions are suitable.

Favorable Conditions

Conditions that allow a seed to germinate (grow), such as moisture, temperature, and oxygen.

Suspended Growth

A state where seeds stop growing and remain dormant until conditions improve.

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.
