Q:

Do plants grow better in sunlight or artificial light?

A:

Plants grow better in sunlight than in artificial light although both sunlight and artificial light provide the energy required for plants to grow. Plants need energy in the form of photons to grow, and there is much more energy emitted by the sun than artificial light.

Not only does artificial light produce less energy than sunlight, the characteristics of the light are also different. The light emitted by the sun contains energy from a vast region of the light spectrum, while artificial light emits very little energy from the red and blue regions. When it comes to most plants, more energy leads to more growth.

    Why do seeds need to be dispersed?

    A:

    Seeds must be dispersed by plants so that offspring are not forced to compete with parent plants for resources. For gardeners and homeowners, it is important to disperse some seeds, such as grass seeds, uniformly to ensure that the resulting lawn looks even and contains no bare patches. A number of forces disperse seeds, including wind, water, animals and seed-spreading tools.

  • Q:

    How are spores and seeds alike and different?

    A:

    Spores and seeds are alike in that plants produce them both to disperse their progeny, allowing new organisms to grow in different locations than their parental organisms. They are different in that spores are very small, single-celled structures, while seeds are relatively large and protected with a seed coat.
