1. Parenchyma cells: These are the most common type of plant cells and are found in the leaves, stems, and roots of plants. They have thin cell walls and are responsible for photosynthesis, storage of nutrients, and providing structural support.
2. Collenchyma cells: These cells have thicker cell walls than parenchyma cells and provide flexible support to young plant parts such as stems and leaves. They are elongated in shape and often found in the outer layers of plant organs.
3. Sclerenchyma cells: These cells have thick, rigid cell walls that are strengthened with lignin. They provide structural support to mature plant parts such as stems, roots, and seed coats. Sclerenchyma cells are often dead at maturity.
4. Xylem cells: Xylem cells are responsible for transporting water and minerals from the roots to the rest of the plant. They are made up of different cell types, including vessel elements and tracheids, which are specialized for water conduction.
5. Phloem cells: Phloem cells are responsible for transporting sugars and other organic compounds produced by photosynthesis throughout the plant. They are made up of sieve tube elements and companion cells, which work together to transport nutrients efficiently.

- Green algae (Chlorophyta) are single-celled or multicellular plants that contain chlorophyll and other photosynthetic pigments. They are found in a wide variety of habitats, including freshwater, saltwater, and soil. Green algae are important primary producers in aquatic food webs.
- Mosses (Bryophyta) are non-vascular plants that lack true roots, stems, and leaves. They are typically found in moist habitats, such as forests and swamps. Mosses play an important role in the cycling of nutrients in ecosystems.
- Ferns (Pterophyta) are vascular plants that have true roots, stems, and leaves. They are found in a wide variety of habitats, including forests, rainforests, and deserts. Ferns are important food sources for many animals.
- Conifers (Pinophyta) are vascular plants that have needle-like leaves and cones. They are found in a wide variety of habitats, including forests, mountains, and deserts. Conifers are important sources of timber and paper.
- Flowering plants (Anthophyta) are vascular plants that produce flowers. They are found in a wide variety of habitats, including forests, grasslands, and deserts. Flowering plants are important sources of food, medicine, and fiber.
