The biome with the longest seed germination time is typically the arctic tundra due to the cold temperatures and short growing season that restricts seed germination and growth. Some seeds in the arctic tundra can remain in the soil for years before conditions are right for germination.
What else can I help you with?
How does the embryo get food for germination?
The embryo in a seed gets its food from the endosperm or cotyledons within the seed. During germination, enzymes break down the stored food reserves in the seed to provide energy for the embryo to grow and develop into a seedling.
What does the cotyledon do?
The cotyledon is a seed leaf found in the embryo of a seed-bearing plant. It stores nutrients for the developing plant embryo to use during germination and early growth stages. Once the plant begins to photosynthesize and produce its own food, the cotyledon is usually shed or becomes nonfunctional.
What conditions are necessasry for seed germination?
the conditions for the seed germination includes appropriate amount of water in the surrounding soil then the nutrients should be available then the carbon dioxide concentration and the absence of chemicals like absisic acid which can cause a seed to remain in a dormant state for long time.
How long does germination take for cantolopes?
Cantaloupe seeds usually germinate in 7-14 days when planted in well-draining soil at a temperature between 70-90°F (21-32°C). Factors such as soil moisture and sunlight can also affect germination time.
How is seed adapted for long survival?
Seeds are adapted for long survival through mechanisms such as dormancy, which allows the seed to remain inactive until conditions are favorable for germination. They also have protective seed coats that shield them from environmental stressors like desiccation and pathogens. Additionally, some seeds contain compounds that help them resist decay and maintain viability for extended periods of time.
Which part of the seed develops into a seedling at the time of germination?
The cotyledon of the seed develops into a seedling at the time of 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.
When you plant a pea describe what happens to the seed when it germinates?
At the time of pea seed germination only plumule comes out from the soil because its mode of germination is hypogeal. The entire seed remains undergound except the plumule.
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.
Why seed germination is tested at regular intervals?
Seed germination is tested at regular intervals to track the progress of germination over time and spot any issues that may arise. This allows researchers to determine the ideal conditions for germination and identify any potential problems early on, enabling adjustments to be made to improve the germination rate and overall success of the process.
Is germination important to plants?
Yes it is important because that is the time the plant emerges from a seed and begins to grow.
Is a seed an independent variable?
It can be. If you are looking at the germination time under different conditions of temperature and humidity etc.
What are the methods for testing seeds for germination?
Generally seed require a few things in order to germinate:Water/ moistureSoil (or a growing medium)Heat/ warmthDarkness or in the case of some seed lightGeneral guide is that the seed should be covered to double the diameter of the seed itself. In the case of many small or fine seed varieties it is best to leave them uncovered with soil.Keep the soil moist during germination, but not too wet as this can cause fungal problems.It is always best to research the seed variety you are germinating if you are not sure of the specifics - as different seeds have different germination periods.
Does the water affect the size of mongo seed?
Yes the water affects the size of mango seed during germination. Water diffuses through the seed coats into the embryo, which has been almost completely dry during the time of dormancy, causing a swelling of the seed; the swelling is often so great that the seed coat is ruptured.
How does the embryo get food for germination?
The embryo in a seed gets its food from the endosperm or cotyledons within the seed. During germination, enzymes break down the stored food reserves in the seed to provide energy for the embryo to grow and develop into a seedling.
What is period of time when a seed starts to grow called?
The period of time when a seed starts to grow is called germination. This process involves the seed absorbing moisture, swelling, and eventually breaking through its outer shell, leading to the emergence of the seedling. Factors such as temperature, moisture, and oxygen availability play critical roles in successfully initiating germination.
Germination time of a green bean?
It takes about 7-10 days for a green bean seed to full germinate.
