Tissue is a group of cells
What are plant tissues?
Plant tissues. ... They differentiate into three main tissue types: dermal, vascular, and ground tissue . Each plant organ (roots, stems, leaves) contains all three tissue types: Dermal tissue covers and protects the plant, and controls gas exchange and water absorption (in roots).
What is tissue class 9 very short answer?
Tissue is a feature of multicellular organisms . Complete Answer: – The word tissue comes from a French verb which means to “weave”. A group of cells having similar shape and function act together to perform a specific function is known as a tissue. All the body parts are made up of tissues including the organs.
What is a plant tissue Short answer?
Plant tissue is a collection of similar cells performing an organized function for the plant . Each plant tissue is specialized for a unique purpose, and can be combined with other tissues to create organs such as leaves, flowers, stems and roots.
What is plant tissue and animal tissue class 9?
A group of cells having common origin, similar structure and performing a definite function is called a tissue. Tissues are found in plants and animals. Plants and animals are made up of many different kinds of tissues. For example, groups of bone cells form bone tissues and muscle cells form muscle tissue.
What are the 4 types of plant tissue?
Plant tissues come in several forms: vascular, epidermal, ground, and meristematic . Each type of tissue consists of different types of cells, has different functions, and is located in different places.
How is plant tissue formed?
Plant cells are formed at meristems , and then develop into cell types which are grouped into tissues. Plants have only three tissue types: 1) Dermal; 2) Ground; and 3) Vascular. Dermal tissue covers the outer surface of herbaceous plants. ... Plant cell types rise by mitosis from a meristem.
What is tissue 9th?
Answer: A group of cells that are similar in structure and work together to do a peculiar function is called tissue. More Resources for CBSE Class 9.
How many types of tissue are there in class 9?
There are three types of permanent tissues: Simple Permanent Tissues. Complex Permanent Tissues. Special or Secretory Tissues.
What is Cell Class 9?
“A cell is defined as the smallest, basic unit of life that is responsible for all of life’s processes .” Cells are the structural, functional, and biological units of all living beings. A cell can replicate itself independently. Hence, they are known as the building blocks of life.
How many tissue types are there?
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 are the types of permanent tissue?
Simple permanent tissues are again classified into three main types. They are parenchyma, collenchyma, and sclerenchyma .
What is an example of a plant tissue?
Dermal tissue , for example, is a simple tissue that covers the outer surface of the plant and controls gas exchange. Vascular tissue is an example of a complex tissue, and is made of two specialized conducting tissues: xylem and phloem. ... The xylem and phloem always lie adjacent to each other (Figure 1).
Which is animal tissue?
Animal tissue refers to the group of cells of similar structure and function in animals. It is of following types: Epithelial tissue , Muscle tissue, Connective tissue, Neural tissue. Epithelial tissue covers the outer surface of the body and internal organs. It lines the body cavities. ... It is made of neurons.
What tissue do both plants and animals have?
Plants have three tissue types: ground, dermal, and vascular. Animals have four: epithelial, connective , muscle, and bone.
What are the three types of meristematic tissue?
There are three types of meristematic tissues: apical (at the tips), intercalary or basal (in the middle), and lateral (at the sides) .
