szöveten

Szöveten, also known as tissue, is a fundamental biological structure found in all living organisms. It is composed of cells and extracellular matrix, which provides structural support and facilitates various biological functions. There are four primary types of tissues in animals: epithelial, connective, muscular, and nervous. Epithelial tissue covers the surfaces of the body and lines internal cavities, while connective tissue provides support and connects different parts of the body. Muscular tissue enables movement, and nervous tissue transmits signals throughout the body.

In plants, tissues are categorized into meristematic, ground, and vascular tissues. Meristematic tissues are responsible for growth and development, while ground tissues include parenchyma, collenchyma, and sclerenchyma, which perform various metabolic and structural functions. Vascular tissues, consisting of xylem and phloem, transport water, nutrients, and organic compounds throughout the plant.

Tissues play a crucial role in maintaining the structure and function of organisms. They facilitate the exchange of gases, nutrients, and waste products, and they provide protection and support. Understanding the properties and functions of different tissues is essential for studying biology, medicine, and agriculture.
