Which plant group has naked seeds in pine cones?
–Gymnosperms are a taxonomic class that includes plants whose seeds are not enclosed in an ovule (like a pine cone). Gymnosperm means as “naked seed”. This group is often referred to as softwoods.
Which plant group has seeds?
Angiosperms . Angiosperms are the largest and most common group of seed-bearing plants. Angiosperms are vascular plants that produce both flowers and fruit. The fruit of the angiosperm encloses the seed, providing nourishment and protection to the growing embryo.
What are the 2 main plant groups?
Plants are classified within the domain Eukaryota. Two major groups of plants are green algae and embryophytes (land plants) .
What are the main group of plants?
The kingdom Plantae consists of four major plant groups on land: bryophytes (mosses), pteridophytes (ferns) , gymnosperms (cone-bearing plants), and angiosperms (flowering plants). Plants may be categorized as vascular or nonvascular.
Why is it called an air plant?
Air plants are usually tiny, easy to grow, and they don’t need soil. As the name implies, air plants absorb nutrients and water from the air through scales on their leaves . They’re having a moment as houseplants because they’re easy to care for and don’t need much light to thrive.
