It protects the plant by covering it in the
e p i de r m is, a single layer of cells. Within
it are the sto ma ta or small pores that
enable the exchange of carbon dioxide
and oxygen and allow the release of
water vapor. 
Plants are composed of tissues,
and here are the three main types.
This tissue makes up most of the plant's interior, storing food
and water, as well as carrying out metabolic functions.
 A t i s s u e is a cluster of cells that work
together to perform a function. 
The vascular tissue is comprised of
the xy lem and phl oem, which bring
food, water, and minerals to different
parts of the plant.

FAQs on Infographics: Tissues - Science Class 9

1. What are the four main types of tissues in the human body?
Ans. The four main types of tissues in the human body are epithelial tissue, connective tissue, muscle tissue, and nervous tissue. Epithelial tissue covers body surfaces and lines cavities, connective tissue supports and binds other tissues, muscle tissue is responsible for movement, and nervous tissue transmits impulses and processes information.
2. What is the primary function of epithelial tissue?
Ans. The primary function of epithelial tissue is to act as a protective barrier covering body surfaces and lining internal organs and cavities. It also plays roles in absorption, secretion, and sensation, depending on its location and type.
3. How does connective tissue differ from other tissue types?
Ans. Connective tissue differs from other tissue types in that it primarily supports, binds, and protects other tissues and organs. It consists of a diverse range of cells and extracellular matrix, which varies in composition, allowing it to have different functions such as storing energy (adipose tissue) or providing structural support (bone and cartilage).
4. What are the different types of muscle tissue, and what are their functions?
Ans. There are three types of muscle tissue: skeletal, cardiac, and smooth. Skeletal muscle is responsible for voluntary movements and is attached to the skeleton. Cardiac muscle makes up the heart and is responsible for pumping blood involuntarily. Smooth muscle is found in walls of hollow organs (like the intestines and blood vessels) and controls involuntary movements.
5. What role does nervous tissue play in the body?
Ans. Nervous tissue plays a crucial role in the body by transmitting electrical impulses that facilitate communication between different parts of the body. It is responsible for processing sensory information, coordinating responses, and controlling bodily functions through the nervous system.
