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.
Scientists change the way plants are classified from time to time, when they discover new types of plants or learn new things about. plants. The two main groups are vascular plants (plants that use stems and. veins to transport food and water), and non-vascular plants (plants. with no roots, stems, or leaves).
