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 do you mean by seed germination?
Seed germination is defined as
the sum of events that begin with hydration of the seed and culminate in emergence of the embryonic axis (usually the radicle) from the seed coat
. From: Plant Growth and Development: Hormones and Environment, 2002.
What is seed 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 the process of seed germination?
germination,
the sprouting of a seed
, spore, or other reproductive body, usually after a period of dormancy. The absorption of water, the passage of time, chilling, warming, oxygen availability, and light exposure may all operate in initiating the process.
What is germination in simple words?
noun, plural:
germinations
.
The stage in which a germ or a living thing starts to sprout, grow and develop
. Supplement. Germination in plants is the process by which a dormant seed begins to sprout and grow into a seedling under the right growing conditions.
What are the 5 stages of germination?
Such five changes or steps occurring during seed germination are:
(1) Imbibition (2) Respiration (3) Effect of Light on Seed Germination(4) Mobilization of Reserves during Seed Germination and Role of Growth Regulators
and (5) Development of Embryo Axis into Seedling.
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 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.
- Dormancy is a state of suspended animation in which seeds delay germination until conditions are right for survival and growth.
What is seed germination and its types?
The following three points will highlight the three main types of seed germination. The three main types are:
(1) Hypogeal Germination (2) Epigeal Germination and (3) Vivipary (Viviparous Germination)
.
Do seeds need light to germinate?
Most seeds germinate best under dark conditions and might even be inhibited by light (e.g., Phacelia and Allium spp.). … Don't confuse seed light requirements with what seedlings need.
All seedlings require sunlight
.
What seeds germinate quickly?
The fastest germinating seeds include everything in the cabbage family –
bok choi, broccoli, kale, cauliflower etc, and lettuce
. The slowest seeds to germinate are pepper, eggplant, fennel, celery, which may take 5+ days. The rest such as tomato, beets, chard, squash, onions, will take about 3 days.
What are the 4 stages of germination?
- The average plant goes through four stages: seed, sprout, seedling, adult plant.
- Seed. Through pollination (pollen reaches the stigma) and ferilization (the pollen and stigma join), a seed is formed. …
- Sprout. The next stage, the sprout, is when the shoot reaches the surface. …
- Seedling. …
- Adult Plant.
What are the 6 stages 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 is germination give example?
The term is applied to the sprouting of a
seedling from a seed of an angiosperm or gymnosperm
, the growth of a sporeling from a spore, such as the spores of Fungus, ferns, bacteria, and the growth of the pollen tube from the pollen grain of a seed plant. 2)Wind ,water and animals help in dispersal of seeds.
What is required for germination?
All seeds need
water, oxygen, and proper temperature
in order to germinate. … Some germinate better in full light while others require darkness to germinate. When a seed is exposed to the proper conditions, water and oxygen are taken in through the seed coat. The embryo's cells start to enlarge.
What are the two types of germination?
- Epigeal Germination: In this type of germination, the hypocotyl elongates rapidly and arches upwards pulling the cotyledons which move above the soil. …
- Hypogeal Germination: In this type of germination, the epicotyl elongates and the cotyledons remain below the soil.
