What are the examples of manipulated variable and responding variable?
Observation-Seeds placed in cotton germinate the same as seeds placed in soil, Hypothesis- Seeds do not need soil for germination Manipulating variables- soil, cotton Responding- height of seeds germinated
Plants living on land get water and nutrients from the?
They get their nutrients from the roots they grow underground. The roots "soak" up the nutrients and water the plant needs.
Why do some seeds fall to germinate if planted in a compact soil?
Seeds may struggle to germinate in compact soil because the density restricts water and air movement, essential for seed activation and root development. Compact soil can also limit the seed's ability to expand and establish a strong root system, leading to inadequate nutrient uptake. Additionally, insufficient aeration may hinder the growth of beneficial microorganisms that support seedling health. Thus, a well-aerated and loose soil structure is generally more conducive to successful germination.
What is the control group in an experiment using soil with compost and seeds?
Soil with seeds is a control group in an experiment using soil with compost and seeds. The results will indicate the role of dark-colored, fresh-smelling, nutrient-rich humus in the appropriate timing and proper development of seeds.
What do radish seeds need to grow?
Moisture and light. You can sprout them between moist paper towels. In the garden, sprinkle radish seeds on top of prepared soil and water in. Plant in a sunny location for best results.
Why does a seed need wet soil to germinate into a tree?
Because seeds will not germinate in arid soil.
Do seeds need soil to germanate?
No, seeds do not necessarily need soil to germinate. Seeds can germinate in a variety of conditions, as long as they have access to moisture, oxygen, and the right temperature. However, soil provides a stable medium for seeds to anchor roots and obtain nutrients for sustained growth.
How much light do seeds need to germinate successfully?
Seeds need varying amounts of light to germinate successfully, depending on the plant species. Some seeds require light to germinate, while others need darkness. Generally, seeds that need light to germinate should be placed on the soil surface or only lightly covered. It is important to follow specific instructions for each type of seed to ensure successful germination.
Do delphinium seeds started indoors need light or dark cold or warmth?
Delphinium seeds need light to germinate, so they should be placed in a location that receives indirect sunlight. They do not require darkness or cold temperatures to germinate. Keep the soil consistently moist and warm around 65-70°F for successful seed germination.

What do bean seeds need to germinate effectively?
soil, water, air, sunlight, and somthing to put all that in
How does ploughing help the seeds germinate?
Seeds sown deeply in soil, fail to germinate because of lack of oxygen. Ploughing aerates the soil and helps in good germination.
Do you need soil when planting grass seeds?
Yes, grass seeds need soil to grow. The soil provides essential nutrients, support, and a medium for the seeds to establish roots and germinate. It's important to choose a quality soil that is compatible with the type of grass you are planting.
A student hypothesized that lettuce seeds would not germinate unless they were covered in soil. the student planted 10 lettuce seeds under a layer of soil and scattered 10 lettuce seeds on top of the?
The student's hypothesis posits that covering lettuce seeds with soil is necessary for germination. By planting 10 seeds under soil and scattering another 10 on top, the student can compare germination rates between the two groups. If the seeds covered in soil germinate while those on top do not, it would support the hypothesis. Conversely, if both groups germinate, the hypothesis would need to be reevaluated.
Will bean seeds germinate without soil or cotton wool?
no they cant
Why do seeds need wet soil to germinate and grow into big tree prove it?
Seeds need to be wet and warm to crack open the shell and start to grow. If it wasn't for this, people would not be able to store seeds.
How can I germinate chamomile seeds effectively?
To germinate chamomile seeds effectively, start by planting them in well-draining soil in a sunny location. Keep the soil consistently moist but not waterlogged. Chamomile seeds require light to germinate, so do not cover them with soil. Keep the seeds at a temperature of around 70F (21C) for optimal germination. Germination typically takes 7-14 days.
