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.
Submit. Botanists divide plants into two large categories: plants that create seeds, and plants that do not. Seed-producing plants are then divided into two more categories. These plants are classified as either gymnosperms, which produce seeds in cones, and angiosperms, which produce seeds in flowers.These two classifications of plants produce the two main types of seeds: naked and enclosed.There are other, less common types of seeds as well.ther seeds, such as sunflower seeds, are not really seeds at all, but the hard fruit of the plant. The actual seed of a sunflower seed is obtained after the hard shell of the fruit is cracked open. Many types of nuts, such as an acorn, are also hard fruits; the nut is actually the seed of the plant.
