How do you describe seed germination?
Seed germination may be defined as the fundamental process by which different plant species grow from a single seed into a plant. This process influences both crop yield and quality. A common example of seed germination is the sprouting of a seedling from a seed of an angiosperm or gymnosperm.
What is germination short answer?
Germination is usually the growth of a plant contained within a seed; it results in the formation of the seedling. Under proper conditions, the seed begins to germinate and the embryo resumes growth, developing into a seedling.
What is germination explain it Class 5?
Answer: The process by which a seed grows into a new plant is called germination. When the seed get all the necessary things like air, water, warmth, space and nutrients from the soil the process of germination starts.
What is germination explain with diagram?
1) Imbibition: water fills the seed. 2) The water activates enzymes that begin the plant’s growth. 3) The seed grows a root to access water underground. 4) The seed grows shoots that grow towards the sun. 5) The shoots grow leaves and begin photmorphogenesis.
What is germination in one sentence?
the process whereby seeds or spores sprout and begin to grow 2. the origin of some development. 1. The poor germination of your seed could be because the soil was too cold.
What are the 4 steps 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. Was this answer helpful?
What three things are needed for germination?
The beginning of the growth of a seed into a seedling is known as germination. All seeds need water, oxygen and the right temperature to germinate.
What is an example of germination?
In hypogeal germination, the cotyledons stay underground. But, in epigeal germination, the hypocotyls first come above the soil surface and then straightens. Examples of hypogeal germination are gram, pea, etc. Examples of epigeal germination are groundnut, bean, etc.
What are the six steps of germination?
For humans, the progression is infant, toddler, adolescent, young adult, middle aged adult, and senior citizen, while plants go from seed to sprout, then through vegetative, budding, flowering and ripening stages.
What are the four stages of germination?
Imbibition phase. Latent phase. Exponential growth phase.
Vitality: The ability of a seed to germinate when provided with optimum condition is described as vitality of the seeds.
What factors affect germination?
Germination is affected by two main factors, moisture and temperature. The seed will remain dormant until it is exposed to moisture enough the husk or outer layer allows the water into the seed itself, at which time the husk normally will split and a tiny shoot will emerge.
What is the first stage of germination?
In the first stage of germination, seeds begin to absorb water, a process called “imbibation.” The seed coating softens as it absorbs water, and the seed then begins to metabolize, as the water triggers release of an enzyme that speeds cellular respiration, where starch is transformed into sugar.
