The reason as to why many plant species, including most grasses, are green is the presence of chlorophyll. This is a bright pigment that absorbs blue and red light, while reflecting green light. Blue light has high frquency and short wavelength, while red has low frequency and longer wavelengths. Reflection of green light by chlorophyll is what accounts for the green color in grass and other plants.
The reason why objects appear to be of given colors is as a result of reflecting that color, while absorbing all other colors. Yellow things are yellow because they reflect yellow and absorb every other color. Pigments are the molecules responsible for absorbing colors. Both plants and animals have pigments.
Although plants have several kinds of pigments, chlorophyll is the most predominant. Chlorophyll reflects green light and absorbs others. For plants to be able to carry out the process of photosynthesis, they need to absorb light. Energy from light is used in converting carbon dioxide into carbohydrates and sugars.
Quanta of light absorbed by chlorophyll are transferred to some special molecules as energy. Stimulation of these molecules sparks an electron that triggers chemical changes within the plant. Chemical energy is further processed into sugar.Learn More
Warm-season grasses must be planted at least two months before the risk of frost in warmer climates and three months in cooler climates, according to The University of Massachusetts Amherst Center for Agriculture. Cool-season grasses must be planted before the daytime temperatures lower to an average of 55 degrees Fahrenheit.Full Answer >
The sun's energy comes from the nuclear fusion reactions that happen within its core. When atoms of hydrogen come together in the core of the sun, they fuse to become another element: helium. This reaction produces energy.Full Answer >
There are several biotic (living) and abiotic (nonliving) factors that are common to all types of desert biomes, or ecosystems, including cacti, fire ants, high daytime temperatures and sand. Biotic factors also include plants and animals such as sagebrush, scorpions, lizards and snakes. Abiotic factors include low temperatures at night, wind, and lack of rainfall.Full Answer >
Although diamond is the strongest naturally occurring substance on Earth, as of 2013, science has developed a new form of carbon called carbyne that surpasses it. Carbyne's ability to withstand stretching surpasses any known substance. Comprised of carbon atoms held together by either alternating single and triple or double atomic bonds, carbyne's tensile strength is almost three times that of diamond.Full Answer >
