I am not sure if you are asking about all plants? If you are asking about flowers, then I would say the answer is monocots and dicots. If you are asking about all trees, then the two groups are angiosperms and gymnosperms. The Plant Kingdom itself actually has 10 divisions: 1. Bryophyta 2. Psilophyta 3. Lycophyta 4. Sphenophyta 5. Pterophyta 6. Cycadophyta 7. Ginkgophyta 8. Gnetophyta 9. Coniferophyta 10. Anthophyta The Coniferophyta division is also referred to as gymnosperms, or trees that make cones. And the Anthophyta division (aka Magnoliophyta) are also referred to as angiosperms, trees that make flowers, and all flowers are sub-divided into monocots and dicots.
He divided animals into two groups- those with red blood and those without it.
Mammals and birds are two groups of animals that are warm-blooded and have a backbone. Both groups regulate their own body temperature internally, allowing them to thrive in a variety of environments.
Aristotle classified animals into two groups based on their red blood and bloodless characteristics. He also classified plants into three groups based on their size and complexity: trees, shrubs, and herbs.
There are two groups of animals that are called a bed. Oysters and clams are both called beds when they are in groups.
A cockroach is an insect. It has six leg and three body parts, head thorax and abdomen.A spider is an arachnid, it has eight legs in four groups of two and two body parts.They are however both 'Arthropods' invertebrate (no internal skeleton) and segmented body, animals.
Vertebrates and invertebrates.
The two first groups of organisms were placed in the categories of plants and animals. This system of classification based on physical characteristics was established by Aristotle in ancient Greece.
He divided animals into two groups- those with red blood and those without it.
Elephants and bees are two animals that have a female as the leader.
Aristotle subdivided his two groups of animals based on their blood. He classified animals as either having blood (vertebrates) or not having blood (invertebrates).

The original first two kingdoms were animals and plants.
Plantae and Animalia are the two groups of living things.Viruses are a curious group outside the 'living things' category, for they cannot reproduce in their own right outside of a living cell. They have DNA and RNA, and maybe they have shed all structures apart from this remnant. Perhaps they descended from other early cellular beings.So the ability to reproduce, to respire, to consume energy, and the presence of a cell wall are the characteristics that define living things.
