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).
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.
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.
The 3 main groups of seedless vascular plants are: ferns, horsetails and club mosses.
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.

the main, maybe most significant reason for plants needing animals is for fertilization. Plants have evolved to reproduce effectively. Seeds need to be dispursed- note how many seeds are designed to attach to the fur of animals such as foxes/ cats or dogs and pollination, vital for genetic variation- sexual reproduction is carried out by bees. Some plants rely on birds eating the seeds as the seeds are only able to grow when they have been excreted with sufficient nutrients from the birds faeces.
All vertebrates reproduce sexually. Birds are one of the main groups of vertebrates, so they reproduce sexually.
