Explanation:
Animal Tissue
Animal body is made of four different types of tissues.
Epithelial Tissue
Muscle Tissue
Connective Tissue
Nerve Tissue
Epithelial Tissue: All organs in the body are lined with a group of tissues called epithelial tissues. They cover the surface of all internal as well as external organs. There are four types of epithelial tissues: Squamous epithelium, Stratified epithelium, Cuboidal epithelium and Columnar epithelium. They may be cuboidal, columnar or even flat. The main functions of these tissues involve protection, secretion, absorption, sensation etc..
Muscle Tissue: This type of tissue forms three types of muscles, namely skeletal (striated or voluntary) muscle, smooth (non-striated or involuntary) muscle and cardiac (heart) muscle. They help in movement by contraction and relaxation of muscles.
Connective Tissue: As the name suggests, they connect the different tissues, organs, and parts of the body. Different types of connective tissues are Areolar tissue, Adipose tissue (fat), Blood, Lymph, Bone, and Cartilage. They connect and support organs and also transport substances between organs.
Nervous Tissue: These tissues are made up of specialized cells called nerve cells (neurons). They conduct and transmit electrochemical impulses between neurons.
Plant Tissue
Plant structure is different from the animal skeletal structure. A plant tissue is different from those in animals. Plant tissues are basically divided into two: Meristematic tissue and Permanent tissue.
Meristematic tissue: These tissues comprise of cells which have the dividing capacity. They are immature and help plants to divide continuously throughout the life. Depending on the site of location, it is of three types. Apical, lateral and intercalary meristems. These meristems enlarge the cell and increase the length and width of the stem, roots, and leaves.
Permanent tissue: Permanent tissues are derivative of meristematic tissue. They don’t have the dividing capability but aid in other functions like conduction of substances, storage of food etc. Two types of permanent tissues are found in plants i.e. simple and complex permanent tissue. Simple permanent tissues include parenchyma, collenchyma, and sclerenchyma while complex tissues are xylem and phloem.

hey mate ,
Animal tissue is classified tissues into four main types:
Epithelial tissue.
It is made up of tightly packed cells arranged in layers with many cell-cell adhesion junctions. Epithelium covers the external body surfaces and internal cavities.
Connective tissues.
Connective tissues differentiate from embryonary mesenchymal cells and can be found all through the animal body. Support, nutrition and storing are typical functions of connective tissues. Histologists further classify connective tissue in several subtypes: connective proper, adipose, cartilage, bone, and blood.
Muscle tissue.
It is made up of muscle cells that have the ability of decrease their length. The cell contraction produces movement of body parts, and therefore allows the movement of animals from a place to another.
Nervous tissue.
Highly specialized cells in information processing (neurons and glia) form the nervous tissue. This tissue receives information coming from both internal and external environments, integrates such information and sends the result to other cells, or typically to muscle cells.
plants tissue is classified into
Merismatic tissues
consist of a group of cells that have the ability to divide. These tissues are small, cuboidal, densely packed cells which keep dividing to form new cells. These tissues are capable of stretching, enlarging and differentiating into other types of tissues as they mature. Meristematic tissues give rise to permanent tissues. Merismatic tissues can be of three types depending on the region where they are present: Apical meristems, lateral meristems, and intercalary meristems.
Permanent tissues
are derived from the merismatic tissues and have lost their ability to divide. They have attained their mature form. They are further classified into two types: Simple and complex permanent tissues.
hope this would help you!!
