the seed is a living organism, although in an apparent state of suspended animation. while the seed lies dormant it still metabolises - that is it uses it reserves of stored energy (stored in the cotyledons) to stay alive.
Some seeds metabolise at a very slow rate and such have a very long "storage life", others may metabolise at a faster rate or have smaller cotyledons - which then shortens their lifespan.
Seed viability (rate of germination after storage) is pretty much constant for a particular kind of seed; this can vary from between a few months up to 20 years. The average though is in the region of 4 to 5 years, after this time the germination of the seed batch will have decreased to almost zero.
there is an account however of a date palm seed being successfully germinated after almost 2000 years! after it was discovered at an archaeological site in the Middle East.
viability deteriorates on in a linear fashion per seed batch.

How many seeds will germinate from a package?
The number of seeds that will germinate from a package can vary based on factors such as seed age, viability, and germination conditions. Some seeds may have a high germination rate, leading to most or all seeds sprouting, while others may have a lower germination rate, resulting in fewer seeds germinating. It's recommended to check the specific information provided on the seed package for more accurate guidance.
Explain why two similar seeds might not germinate at the same time?
Even if seeds are similar, various factors such as variations in moisture levels, temperature, and nutrient availability in the growing medium can affect germination time. Additionally, genetic differences between seeds or variations in the age of the seeds can also impact their germination rate and timing.
What is the relationship between seed viability and seed age?
Seed viability typically declines with age, as the physiological and biochemical processes within the seed deteriorate over time. Factors such as moisture content, temperature, and storage conditions also influence this relationship. Generally, seeds stored under optimal conditions can retain viability for several years, but as they age, the likelihood of germination decreases significantly. Therefore, understanding this relationship is crucial for effective seed storage and agricultural practices.
How does culture age affect the result of a spore?
Culture age can significantly influence the results of a spore, as younger cultures tend to produce more viable spores with higher germination rates due to their active metabolic state. In contrast, older cultures may show reduced spore viability and germination potential due to nutrient depletion, accumulation of metabolic byproducts, and cellular aging. Additionally, the morphological and physiological characteristics of spores can change with culture age, affecting their resilience and adaptability in various environments. Thus, optimizing culture age is crucial for achieving the best outcomes in spore-related applications.
Does weight affect the rate of respiration?
Weight can indirectly affect the rate of respiration. Generally, individuals with higher weight may have increased metabolic demands, leading to higher rates of respiration to meet those demands. However, weight alone is not the sole determinant of respiration rate, as factors such as fitness level, age, and overall health also play important roles.
What are the answers for a science homework sheet about seed germination?
Seed germination is the process by which a seed develops into a new plant. It typically requires optimal conditions such as moisture, temperature, and oxygen. The seed absorbs water, swells, and eventually breaks through its outer coat, allowing the embryo to grow. Essential factors influencing germination include soil type, light exposure, and the age of the seed.

Does age affect a person heart rate after exercise?
yes
Does age affect the heart rate of humans hypothesis?
Yes
Can sunflower seeds go bad even if they're unopened?
The shelf life of sunflower seeds is affected by seed moisture content, seed age, and ambient temperature. So the expiration date's sooner the older the seed; the further away the temperature in either direction from 25 degrees C/77 degrees F; the closer the relative humdity to 75%, the higher the seed moisture content, the greater the damage to seed membranes.
What is the variables for cress seeds?
When studying cress seeds, key variables include temperature, light exposure, water availability, soil type, and nutrient levels. These factors can significantly influence germination rates, growth speed, and overall health of the plants. Additionally, variations in seed quality and age can also affect the outcomes of any experiments or observations.
What can influence a person's metabolic rate?
Gender, age, and body shapes/sizes can affect a person's metabolic rate. ***Apex: All of the above
Does grade level affect heart rate?
Do you mean what grade in school a child is in? If that's what you mean, then no, grade level doesn't affect heart rate, but there is probably a correlation between a child's age -- which is closely associated with his grade level -- and his heart rate.
What is a question someone would ask about pulse rate that can be shown in an experiment?
Is there a connection between age and pulse rate? That's the one I used and i got it right
