Germination | Description, Process, Diagram, Stages, Types,
Sep 10, 2024 · 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.
Germination - Wikipedia
Germination is the process by which an organism grows from a seed or spore. 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 fungi, ferns, bacteria, and the growth of the pollen tube from the pollen grain of a seed plant.
Germination - Definition, Process and Temperature - Biology …
Feb 11, 2018 · Germination Definition. Germination refers to the process by which an organism grows from a seed or a spore. The most common forms of germination include a seed sprouting to form a seedling and the formation of a sporeling from a spore. Thus, germination occurs primarily in plant and fungal species.
Seed Germination: Definition, Steps, & Factors Affecting Them
Feb 2, 2023 · What is seed germination in plants: what do seeds need to germinate, stages of the process described with experiment and diagram
2.2: Introduction to Seed Germination - Biology LibreTexts
Jul 27, 2022 · At germination, the seed’s metabolic pathways are activated, leading to embryo growth and emergence of a new seedling. Germination begins with activation by water uptake. We call this imbibition, and sometimes the seed or fruit requires special treatment for water to get into the seed and start this process.
Seed Germination: What Do Seeds Need to Sprout?
Nov 17, 2023 · Germination is the process a seed goes through when it “wakes up” from its dormant state and starts to grow. Seeds are self-contained systems that contain most of what they need to get themselves started, but there are three important triggers that kick off germination: air, water, and warmth.
Seed germination - Process, Necessity, and its Major Factors
Jul 20, 2018 · 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.
16.4B: Germination of Seeds - Biology LibreTexts
Dec 31, 2020 · When grass seeds like corn (maize) or oats (shown here) germinate, The primary root pierces the seed (and fruit) coverings and grows down. The primary leaf of the plant grows up. It is protected as it pushes up through the soil by the coleoptile - a hollow, cylindrical structure.
Process of Seed Germination: 5 Steps (With Diagram) - Biology …
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.
Germination of Plant - Biology Reader
Germination of a plant refers to a phenomenon in which a seed germinates to form a new seeding or plant. The germination process results in the emergence of the radicle (primary root) and plumule (primary shoot). Before germination, the seed remains dormant in the soil.
