Gymnosperms and angiosperms
Green plants are classified into two main groups: non-vascular plants (like mosses and liverworts) and vascular plants (like ferns and seed plants). Vascular plants are further divided into two groups based on whether they reproduce through seeds (gymnosperms and angiosperms) or spores (like ferns).
The five main groups of plants are mosses, ferns, gymnosperms, angiosperms, and algae. Mosses, like Sphagnum, are non-vascular and thrive in moist environments. Ferns, such as the Boston fern, are vascular plants that reproduce via spores. Gymnosperms, including pine trees, bear seeds in cones, while angiosperms, like roses and apple trees, are flowering plants that produce seeds within fruits.
There is one division of angiosperms, Magnoliophyta, which is divided into two classes: monocots and dicots. Monocots are angiosperms with seeds having single cotyledons and dicots are the ones with seeds having two cotyledons.
Ferns, club mosses, and horsetails share two characteristics. They have true vascular tissue and they do not produce seeds. Instead of seeds, these plants reproduce by releasing spores.

The main function of seeds is to reproduce and propagate the plant species they come from. Seeds contain the genetic material needed for new plant growth and are capable of germinating and developing into new plants under the right conditions.
Botanists typically categorize plants into four main groups: flowering plants (angiosperms), conifers and cycads (gymnosperms), ferns and their relatives (pteridophytes), and mosses and liverworts (bryophytes). Angiosperms produce flowers and seeds enclosed in a fruit, while gymnosperms have seeds that are not enclosed. Pteridophytes reproduce via spores and have vascular systems, while bryophytes are non-vascular and rely on water for reproduction. Each group exhibits distinct characteristics and reproductive strategies.
The four main groups of plants are mosses, ferns, gymnosperms, and angiosperms. Mosses are non-vascular plants, ferns are seedless vascular plants, gymnosperms have naked seeds (like pine trees), and angiosperms have seeds enclosed in fruits (flowering plants).
The two main groups of flowering plants are monocots and dicots. Monocots have seeds with one cotyledon (seed leaf) and typically have parallel veins in their leaves, while dicots have seeds with two cotyledons and usually have branching veins in their leaves.
While plants and animals are the main groups that reproduce, other organisms like fungi, protists, and bacteria also have methods of reproduction. These organisms have their own unique processes for generating new individuals within their respective kingdoms.
