2nd answer ;-Simple permanent tissues are found below the epidermis of the plant, spread around in layers of cells. Parenchyma is found in the cortex of stem and roots and in the mesophyll of leaves. Collenchyma is found in the leaf stalk and leaf midribs below the epidermis.
3rd answer :-Permanent tissues are made up of cells that do not undergo cell division. The cells in these tissues are modified to perform some specific functions. The cells in permanent tissues are fully grown, bigger in size, and have a certain shape. ... Permanent tissues are derived from the meristematic tissue.
4th answer :- It has four main components: plasma, red blood cells, white blood cells, and platelets. Blood has many different functions, including: transporting oxygen and nutrients to the lungs and tissues. ... carrying cells and antibodies that fight infection.
5th answer :-There are the prominent nucleus and Nissl's granules in the cell body. There are short brush-like structures arising from the cell body called as dendrite. The axon is a long extension of the cell body ending in a bunch of branches. The axon is covered by a fatty layer known as myelin sheath.
