A cargo ship missing since Thursday with 33 crewmen aboard sank off the coast of the Bahamas during hurricane Joaquin, the US Coast Guard says.
The plant kingdom is a rich and varied world, with species such as green algae that grow on the microscopic level as well as monstrously large, imposing beauties like the giant redwood trees. Botanists, who study plant species, have identified more than 300,000 species of plants that presently exist.The existing species can be broken down into a few groups, including bryophytes, ferns, fern allies, and seed plants.eed plants, which are also referred to as spermatophytes, reproduce by producing seeds. Flowering plants and conifer trees are examples of this type of plants. Many fruits and vegetables are also part of the seed plant variety. Ad. Ferns, like bryophytes, reproduce via spores.
There are about 300â315 thousand species of plants, of which the great majority, some 260â290 thousand, are seed plants (see the table below). Green plants provide most of the world's molecular oxygen and are the basis of most of the earth's ecologies, especially on land. Plants that produce grains, fruits and vegetables form humankind's basic foodstuffs, and have been domesticated for millennia. Plants play many roles in culture.
