The number of cell layers and cell types together give rise to 6 different types of epithelial tissue.

  • straightforward squamous epithelia
  • simple epithelia with cuboids.
  • epithelia with simple columns.
  • squamous epithelia with layers.
  • Cuboidal epithelia with stratification.
  • columns of stratified epithelia.

What type of tissue is blood?

A form of connective tissue known as blood contains a fluid matrix known as plasma. It contains platelets, white blood cells, and red blood cells. Because it links the various bodily systems, carries oxygen and nutrients to every part of the body, and eliminates waste, blood is regarded as a type of connective tissue.

What is connective tissue explain its types Class 9?

A few cells that are present in the intercellular framework of collagen or elastin—protein fibers secreted by the cells—make up connective tissue. Additionally, the cells secrete a slim polysaccharide gel that, when combined with fibers, forms the matrix or ground substance.

What is cohesion tension theory?

According to the cohesion-tension theory (C-T theory) developed by Dixon and Joly (1894) and Boehm (1893), the only cause of water ascent in trees is the transpirational pull of continuous water columns in the xylem conduit that connects the roots to the leaves.

Why are leaves green?

As a result, plants and their leaves appear green because each cell’s internal reactions are powered by a “special pair” of chlorophyll molecules that use the red end of the visible light spectrum. We see the green light that was not used because it was reflected by the leaf.
