Question

Philoid · Accepted Answer

(a) Simple epithelium and compound epithelium

Simple epithelium	Compound epithelium
1. This tissue is made up of a single layer of cells, resting on the basement membrane, e.g., squamous epithelium.	1. This tissue is made up of many layers of cells and the deepest layer is attached to the basement membrane, e.g., stratified.

(b) Cardiac muscle and striated muscle

Cardiac muscle	Striated muscle
1. They are called involuntary muscles.	1. They are voluntary because they can be moved at will.
2. They are found in the contractile tissue present only in the heart.	2. Most striated muscles are attached to bones by tendons.
3. The cells contract as a unit. When one cell contracts, the signal stimulates the neighbouring cells.	3. Each striated muscle is covered by a thin elastic sacrolemma.
4. They show any striation.	4. Alternate light and dark bands are present giving a striated appearance.

(c) Dense regular and dense irregular connective tissues

Dense regular connective tissue	Dense irregular connective tissues
1. In this tissue the collagen fibers are present in rows between many parallel bundles.	1.These tissues have fibroblasts and many fibers that are oriented.
2. They are present in tendons, which attach skeletal muscles to bones and ligaments, which attach one bone to another.	2. These tissues are present in the skin.

(d) Adipose and blood tissue

Adipose tissue	Blood tissue
1.These loose connective tissue are located beneath the skin.	1. Blood is a fluid connective tissue containing plasma, RBC, WBC, and platelets.
2.The cells of these tissues are specialized to store fats which are formed by the conversion of excess of nutrient which are not used immediately.	2. It is the main circulating fluid that helps in the transport of various substances.

(e) Simple gland and compound gland

Simple gland	Compound gland
1. These glands are made up of cells forming a single tube, which opens directly on the surface organ.	1. These glands are made up of cells forming many alveoli. Each alveoli joins with the other ducts and finally empties its contents into one large duct, which leads to the surface.
