some of the tissues is formed in multi layer ?why do you think so?
Answers
Answer:
The 2 Major Criteria for the Classification of plant tissues are given below.
Based on part of the plant, they are present in.
Based on the kind of cells they contain.
Classification of Plant Tissues – Based on its location in the Plant
Epidermal tissues – It covers the outside of a plant in a single layer of cells.
Ground tissues – It covers the interiors of a plant.
Vascular tissues – Transports water and dissolved substances inside the plant.
Classification of Plant Tissues – Based on the kind of cells they contain.
Meristematic – There are 3 major types in this.
Permanent – There are 2 major types under this named as Simple and Complex. Simple is further subdivided into 3 types named parenchyma, collenchyma, and sclerenchyma. The complex is further subdivided into 2 types named Xylem and Phloem.
What is Meristematic Tissue?
The growth in length and diameter of plants is carried out by this tissue. They are broadly classified as
Apical Meristem – It is present at the apical portion of stems and roots. It is responsible for the growth in the length of the plants.
Lateral Meristem – It is present at the radial portion of the stems and roots. It is responsible for the growth in the thickness of the plants.
Intercalary Meristem – It is present at the internodes or the base of the leaves.
Is Xylem a Tissue?
Xylem is a plant vascular tissue that transports water and dissolved minerals from the roots to the rest of the plants and also provides physical support. Xylem tissues contain tracheary elements which are known as water-conducting cells. Xylem tissue contains fiber cells for support and parenchyma for the storage of various substances.
Is Blood a Tissue?
Yes, blood is fluid but can be considered as a tissue also since it is a compilation of cells that are specialized in serving unique functions. These cells are suspended in a liquid matrix (plasma), which makes the blood fluid.
