Answers
GPT-4o mini
A tissue is a group of cells that work together to perform a specific function in an organism. In multicellular organisms, tissues are organized into organs, which then form systems. There are four primary types of tissues in animals:
1. **Epithelial Tissue**: Covers body surfaces, lines cavities and organs, and forms glands. It serves functions such as protection, absorption, secretion, and sensation.
2. **Connective Tissue**: Supports, binds together, and protects tissues and organs of the body. It includes a wide variety of tissues such as bone, adipose (fat) tissue, blood, and cartilage.
3. **Muscle Tissue**: Responsible for movement. There are three types of muscle tissue: skeletal (voluntary movement), cardiac (involuntary movement of the heart), and smooth (involuntary movement in organs).
4. **Nervous Tissue**: Composed of neurons and supportive cells (glia) and is responsible for transmitting signals throughout the body, facilitating communication and coordination.
In plants, the concept of tissue also applies, with different types of plant tissues serving specific functions, including meristematic tissue (growth), permanent tissue (support and photosynthesis), and vascular tissue (transport of nutrients and water).
