Algae,Mosses,and Ferns are pretty different. When it comes to angiosperms and gymnosperms they are more similar that differant.They both have seeds and vascular tissue. So how do you tell the difference? Well,Check it out.
1. They have extensive root systems that allow them to draw water from the earth.
2. Their roots and stems are capable of secondary growth-the rings around the trees.
3.The sporophyte protects the gametophye from drying out.
4. They are able to fertilize without water since the pollen grains are able to directly fertilize the gametophye through the pollen tube.
5. The development of waterproof seeds, which allow the seeds to survive in harsh conditions and dormant conditions.
Gymnosperms include ginkos,cycads,gnetophytes, and conifers.
