The tallest living animal is the giraffe, which usually stands 14 to 17 feet tall. Its height allows it to feed easily from trees and also obtain a long visual range over its habitat.
Much of a giraffe's height comes from its long neck, which in adults measures about 6 feet. Giraffes only have seven neck vertebrae, just as all other mammals do, but each vertebra is greatly elongated. Giraffes gain another 6 feet of height from their long legs. They can run about 35 miles an hour for short distances but cannot cross rivers or swamps easily, as they are too heavy.Learn More
There are several methods of propagating a rubber tree plant, with air layering being the preferred method. To propagate by air layering, a section of the stem is cut, treated with rooting hormone and wrapped with moss. Rooting takes two to three weeks.Full Answer >
Photosynthesis is the process by which green plants manufacture their own food. The process takes place in small structures within the plant’s cells called chloroplasts. Photosynthesis evolved about 3 billion years ago, yet it remains the most important method for harvesting the sun’s energy on the planet.Full Answer >
Plants get energy from the sun through a process called photosynthesis. Plants convert light into chemical energy which is stored in the organism as sugars.Full Answer >
Both auxins and gibberellins are plant hormones that function to promote plant growth through cell elongation. Auxins, in particular, respond to the influences of light availability and gravity, and also promote the differentiation of vascular tissue. Gibberellins are more responsible for growing shoots and promoting cell division in addition to cell elongation.Full Answer >
