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.
The period durning which an organism growth and activity decreases or stops is called?
The period when an organism growth and activity decreases is called dormancy. This is taught biology.
Why do seeds go through a period of dormacy?
Seeds undergo a period of dormancy as a survival strategy, allowing them to withstand unfavorable environmental conditions. This dormancy ensures that germination occurs only when conditions are optimal for growth, such as the right temperature, moisture, and light. It also prevents seeds from germinating too early, which could lead to seedling death or poor establishment. Additionally, dormancy helps synchronize germination with seasonal cues, increasing the chances of successful reproduction.
What is a period of decreased activity during which a plant stops growing called?
A period of decreased activity during which a plant stops growing is called dormancy. During dormancy, plants conserve energy and resources by reducing metabolic processes until conditions become favorable for growth again.
Distinguish between Seed doemancy and Quiescence?
Seed dormancy refers to a period where a viable seed fails to germinate even under favorable conditions due to physiological factors, while quiescence is a temporary suspension of metabolic activity in an already mature seed until conditions become suitable for germination. Dormancy is an inherent characteristic of certain seeds, while quiescence is a temporary state that can be triggered by environmental factors.

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.
What ends dormancy of a seed?
A combination of factors can trigger the end of seed dormancy, such as exposure to water, light, or certain temperatures. Additionally, hormones within the seed can change, signaling the end of dormancy and the beginning of germination.

How is germination promoted after a period of dormancy?
This depends on the type of seed. Providing the right conditions for the type of seed is vital. For instance most alpine seeds require a period below zero before they will germinate.
Do cherry seeds require stratification before planting?
Yes, cherry seeds typically require stratification, which is a period of cold and moist conditions, before planting to help break dormancy and promote germination.
Can a seed be viable and dormant at the same time?
Yes, seed can be viable and dormant at a same time because dormancy is natural and physiological but temporary barrier for seed germination while non-vaibility is permanent unability of seed germination.
What is long period of inactive where organisms survive unfavorable environmental conditions?
That is called dormancy. During dormancy, organisms go into a state of reduced metabolic activity to conserve energy until conditions become more favorable for growth and reproduction.
