Germination | Description, Process, Diagram, Stages, Types,
2024年9月10日 · 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.
Plant Growth – Definition & Stages - Science Facts
2023年2月3日 · Plant growth is an irreversible increase in their size, mostly in length. Most plants grow throughout their life. As plants are multi-cellular organisms, they grow in two ways – cell growth and cell division. Cell growth increases the cell …
Germination - Wikipedia
Germination is usually the growth of a plant contained within a seed resulting in the formation of the seedling. It is also the process of reactivation of metabolic machinery of the seed resulting in the emergence of radicle and plumule .
Seed Germination - an overview | ScienceDirect Topics
Seed germination is a process by which a seed develops into a new plant. It is a multiphase process, starting from seed imbibition (water uptake by seed), activation of plant metabolic enzymes, seed coat rupture, and finally the development of roots, shoots, leaves, and other plant organs (Bewley, 1997).
Seed Germination: What Do Seeds Need to Sprout?
2023年11月17日 · 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.
How Does A Seed Grow Into A Tree? - Science ABC
2023年10月19日 · The process by which a seed transforms into a plant (seedling) in optimum sunlight, air, and water is called germination. The seed can grow within its range of minimum and maximum temperatures. Any temperature above this range can either damage the seeds or …
Seedling Growth - an overview | ScienceDirect Topics
Seedling growth, which starts when germination is completed, signals a shift in priorities to a rapid growth of root and shoot and establishment of a photosynthetic seedling. In the process, reserve foods are hydrolyzed and provide fuel for energy and building blocks for new macromolecules.
2.2 Introduction to Seed Germination – The Science of Plants
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.

SLO 20.03: Describe the characteristics of basic plant growth requirements; SLO 20.04: Describe the characteristics of favorable conditions and duration for germination; SLO 20.05: Identify given plant species with their scientific names based on their key features; SLO 20.06: Explain how seed germination related to seed quality
Seed - Germination, Embryo, Plant Growth | Britannica
2024年10月11日 · Seed - Germination, Embryo, Plant Growth: Dormancy has at least three functions: (1) immediate germination must be prevented even when circumstances are optimal so as to avoid exposure of the seedling to an unfavourable period (e.g., winter), which is sure to follow; (2) the unfavourable period has to be survived; and (3) the various dispersing ...
