What are the groups of cells?
Cells fall into two broad groups: prokaryotes and eukaryotes. Prokaryotic cells are smaller (as a general rule) and lack much of the internal compartmentalization and complexity of eukaryotic cells.
How many types of cells are there?
The cells inside our bodies are “specialized.” This means that each type of cell performs a unique and special function. For this reason, each of the 200 different types of cells in the body has a different structure, size, shape, and function, and contains different organelles.
What are tissue groups?
The Group of tissues performing particular functions in the body is called an organ or an organ is a structure composed of at least two or more tissue types. Each tissue performs a specific function of the body. Several organs together constitute an organ system.
What are groups of organs called?
An organ system is a group of organs that work together as a biological system to perform one or more functions. Each organ does a particular job in the body, and is made up of distinct tissues.
What are the 4 major tissue types and their characteristics?
There are 4 basic types of tissue: connective tissue, epithelial tissue, muscle tissue, and nervous tissue. Connective tissue supports other tissues and binds them together (bone, blood, and lymph tissues). Epithelial tissue provides a covering (skin, the linings of the various passages inside the body).
What is tissue class 9th?
A tissue is defined as a cluster of cells which are similar in structure and work together to perform a particular function. 2. The use of tissues in multicellular organisms is to provide structural and mechanical strength as well as to allow division of labour.
Why is tissue class 9 important?
Ans: The group of cells similar in origin and structure can be defined as a tissue. These cells are specialised to perform a particular function. For instance, muscle cells in our body form muscle tissues that bring about body movement or specific functions.
What is the function of stomata class 9th?
Functions of Stomata The major function of stomata is the exchange of gases by taking carbon dioxide from the atmosphere and giving out oxygen that is used by human beings and animals. They help in photosynthesis and transpiration.
What are alveoli 10?
Answer: (i) The alveoli are thin walled and richly supplied with a network of blood capillaries to facilitate the exchange of gases between blood and the air filled in alveoli. (ii) Alveoli have balloon – like structures with thin elastic walls. These provide maximum surface for exchange gases.
