Viruses are not cells.They are a very small infectious particle consisting of nucleic acid enclosed in a protein coat and, in some cases, a membranous envelope. Bryophyta are mosses. They are the most common seedless nonvascular plants. Pterophyta are ferns. The vascular system allows them to get off the fround resulting in more photosynthesis. The roots allow absorption of water and nutrients. The leaves allow for more photosynthesis. Gymnosperms are cone bearing plants. Angiosperms are flowering plants. There are two major types of Angiosperms. Monocots and Dicots. Monocots have a single seed leaf. The leaf veins are usually parallel. The flower parts are usually in multiples of three. The bundles of vascular tissue are scattered in the stem. Dicots have two seed leaves. Leaf veins are usually netlike. Flower parts are usually in multiples of four or five. They have bundles of vascular tissue in rings in stem.
Fungal cell walls are made of chitin. Plant cell walls are made of cellulose. There are sac fungi which form a reproductive sac. Yeasts are single-celled sac fungi. Animals are diverse but share common characteristics. 97% of all animal species are invertebrates. Sponges and cnidarians are the simplest animals.Flatworms, mollusks, and annelids belong to closely related phyla.
