Plant tissues and animal tissues

Wednesday, January 30, 2013


In multicellular organisms, the cells are organized into tissues, organs & organ systems. Tissue is a group of physically linked cells with common origin specialized for a particular function or functions. We can divide tissues to plant tissues and animal tissues.

Types of plant tissues, their structure & function

                    •   Plant tissues can be classified into two groups
                      •   Simple tissues – mainly one type of cells
                      •   Complex tissues – more than one type of cells
                    •   Simple plant tissues are divided into three groups
                        1. Parenchyma      2. Collenchyma     3. Sclerenchyma
                    •   The structure, function and distribution of simple plant tissues.
                    •   Modified parenchyma cells and their distribution and function
                    •   Complex plant tissues are divided into two groups.
                         1. Xylem               2. Phloem
                    •   Structure, function and distribution of complex plant tissues.
                    •   Observation and identification of  different plant tissues under light microscop

Main types of animal tissues and their characters.

    
               •   Structure-function relationship of tissues.
                   •   Microscopic observations and identifying types of tissues.
                   •   Types of animal tissues, their structures and functions.
                   •   Basically animal tissues are grouped into four categories
                          1. Epithelial tissue
                          2. Connective tissue
                          3. Muscle tissue
                          4. Nervous tissue
                      •   Epithelial tissue
                     
                      •   There are two general classes of epithelium
                             1. Simple
                             2. Stratified
                      •    These classes are further subdivided into three based upon the shape of
                        the cells
                          1. squamous
                          2. cuboidal
                          3. columnar
                     

Connective tissues

                       
                        •   Divided into two major classes
                           1. Connective tissue proper
                           2. Special connective tissue
                        •   Connective tissue proper is divided into two
                           1. Loose connective tissue
                           2. Dense connective tissue
                       
                    •    Special connective tissues are classified into three
                        1. Cartilage
                        2. Bone
                        3. Blood
                   

 Muscle Tissue

                        •   There are three kinds of muscles
                           1. Smooth muscle
                           2. Skeletal muscle
                           3. Cardiac muscle
                       

 Nervous tissue

                        •   There are three types of neurons
                           1. Sensory neurons
                           2. Motor neurons
                           3. Inter neurons
                    •    Observe and identify the different types of animal tissues under light microscope
