An example of an environmental cue for germination is?
An example of an environmental cue for germination is the presence of water. When a seed absorbs water, it triggers biochemical processes within the seed that lead to germination. This cue initiates the growth of the embryo within the seed and the development of a new plant.
What provides for the germination seed?
The germination of a seed is triggered by the right environmental conditions, such as moisture, oxygen, and warmth. Once these conditions are met, the seed will absorb water and begin to sprout. The process of germination allows the seed to grow into a seedling and eventually develop into a plant.
Extreme environmental conditions such as heat and cold may affect the timing of a mature seed's what?
Extreme environmental conditions such as heat and cold may affect the timing of a mature seed's germination. These conditions can influence the seed's physiological processes, potentially delaying or accelerating the onset of germination depending on the specific temperature and moisture levels. Additionally, extreme conditions can impact the seed's dormancy period, which is crucial for ensuring that germination occurs under optimal environmental circumstances.
What is the outer shell of a seed called?
The outer shell of a seed is called the seed coat or testa. This protective layer encases the seed, safeguarding the embryo and stored nutrients from environmental factors and potential damage. The seed coat also plays a role in regulating water absorption, which is crucial for germination.
What does germination as in plants mean?
Germination is the process by which a seed sprouts and begins to grow into a seedling. It involves the reactivation of the embryo within the seed and the emergence of the root and shoot. Germination is triggered by factors like water, temperature, and oxygen.

What are the three most important factors which control seed germination?
Temperature has the greatest effect on seed germination.
How long does it take for grass seed germination to occur?
Grass seed germination usually takes about 5 to 10 days, but it can vary depending on the type of grass and environmental conditions.
What are the most important factors which control seed germination?
Temperature and Moisture.

What is seed germenation?
Seed germination is the process by which a seed begins to grow into a new plant. It typically involves the seed absorbing water, breaking dormancy, and sprouting a root and shoot. Germination is triggered by environmental conditions such as moisture, temperature, and light.
What is seed vitality?
Seed vitality refers to the health and potential of seeds to germinate and grow into healthy plants. It encompasses factors such as seed quality, vigor, and longevity, indicating how well seeds can withstand storage conditions and environmental stresses. High seed vitality is crucial for successful crop production, as it influences germination rates and overall plant development. Testing for seed vitality often involves assessing factors like moisture content, germination tests, and the presence of diseases or damage.
What do you mean by dormancy in a seed?
Seed dormancy is a condition of plant seeds that prevents germination when the seeds are under optimal environmental conditions for germination. Living, non dormant seeds germinate when soil temperatures and moisture conditions are suited for cellular processes and division; dormant seeds do not.
How does electricity effect seed germination?
Electricity can potentially affect seed germination by stimulating enzymatic activity and metabolic processes within the seed, leading to quicker growth and improved germination rates. However, the impact can vary depending on the type of seed, the intensity and duration of the electric field, and other environmental factors. Further research is needed to fully understand the mechanisms and outcomes of using electricity for seed germination.
What is it called when the seed coat bursts and a new plant starts growing?
It is called germination. During germination, the seed coat ruptures, and the embryo inside begins to grow into a new plant. This process is triggered by favorable environmental conditions such as moisture, temperature, and light.
