What are the main tissue systems in the anatomy of flowering plants?

In the anatomy of flowering plants, there are three main tissue systems:

1. Dermal Tissue System: This system forms the outer protective covering of the plant. It includes the epidermis, which is a single layer of cells covering the entire plant body and providing protection against water loss, injury, and infection. Some epidermal cells differentiate into specialized structures like trichomes and guard cells.
2. Ground Tissue System: This system forms the bulk of the plant body and is involved in functions like photosynthesis, storage, and support. It includes the cortex, pith, and mesophyll cells. The ground tissue is composed of three types of cells: parenchyma, collenchyma, and sclerenchyma.
3. Vascular Tissue System: This system is responsible for the conduction of water, minerals, and nutrients throughout the plant. It consists of two main types of tissues: xylem and phloem. Xylem transports water and minerals from roots to other parts of the plant, while phloem transports organic nutrients from the leaves to other parts of the plant.
