What are the 5 steps of germination?
The process of seed germination includes the following five changes or steps: imbibition, respiration, effect of light on seed germination, mobilization of reserves during seed germination, and role of growth regulators and development of the embryo axis into a seedling.
What are the 4 steps of germination?
The Seed Germination Process
- Step 1: Imbibition: water fills the seed.
- Step 2: The water activates enzymes that begin the plant’s growth.
- Step 3: The seed grows a root to access water underground.
- Step 4: The seed grows shoots that grow towards the sun.
- Step 5: The shoots grow leaves and begin photmorphogenesis.
What are the 8 stages of germination?
The Seed Germination Process :
- Imbibition: water fills the seed.
- The water activates enzymes that begin the plant’s growth.
- The seed grows a root to access water underground.
- The seed grows shoots that grow towards the sun.
- The shoots grow leaves and begin photmorphogenesis.
What is the seed germination process?
In the process of seed germination, water is absorbed by the embryo, which results in the rehydration and expansion of the cells. Shortly after the beginning of water uptake, or imbibition, the rate of respiration increases, and various metabolic processes, suspended or much reduced during dormancy, resume.
What are the 3 stages of seed germination?
There are three major stages in the germination process. These are the imbibition of water, increased metabolic activity, and swelling of cells. Germination begins with the seed’s imbibition (absorption) of water. Most dormant seeds have 5 to 10 percent moisture content.

What are the 3 general stages of seed germination?
In general, germination process can be distinguished into three phases: phase I, rapid water imbibition by seed; phase II, reactivation of metabolism; and phase III, radicle protrusion [6].

What are the 6 stages of germination?
Learn The Six Plant Growth Stages
- Sprout. Each seed contains a small parcel of nutrients that is all they need to germinate and begin growing their first pair of leaves.
- Seedling.
- Vegetative.
- Budding.
- Flowering.
- Ripening.
What are 2 methods of planting seeds?
In general, a farmer who intends to raise a crop has to choose between these two methods of planting: direct seeding and transplanting.
What are the stages of planting a seed?
Background: The plant life cycle consists of four stages; seed, sprout, small plant, and adult plant. When the seed gets planted into the soil with water and sun, then it will start to grow into a small sprout.
What are the 5 factors that affect seed germination?
Major Factors Necessary for Seed Germination in Plants (Internal and External Factors)
- Water: Germination cannot occur unless and until the seed is provided with an external supply of water.
- Oxygen:
- Temperature:
- Light:
- Other factors:
What are the steps of seed germination?
Sprout. Each seed contains a small parcel of nutrients that is all they need to germinate and begin growing their first pair of leaves.
What triggers seed germination?
Pre-Soak Your Seeds Before Planting. Plants lie dormant until the seeds detect enough regular moisture to be able to grow.
What are the three different types of seed germination?
Imbibition. The seed rapidly takes up water and the seed coat swells and softens.
What is the first step in the germination of a seed?
The first step in the germination of a seed is the absorption of water. The first structure to break through the seed coat is the radicle. What are three ways scarification occurs naturally?
