section n 5th question option b: A simple columnar epithelium is a single layer of columnar cells attached to the basement membrane, with oval-shaped nuclei located in the basal region. In humans, a simple columnar epithelium lines most organs of the digestive tract including the stomach, small intestine, and large intestine. Simple columnar epithelia line the uterus.
Simple columnar epithelium is further divided into two categories: ciliated and non-ciliated (glandular). The ciliated part of the simple columnar epithelium has tiny hairs which help move mucus and other substances up the respiratory tract.
The shape of the simple columnar epithelium cells are tall and narrow giving a column like appearance. the nuclei are located closer along the basal side of the cell.
They are PRESENT in digestive track bronchioles of the respiratory tract and in the oviduct of the female reproductive tract. The non-ciliated columnar epithelium is also found in the inner lining of small intestines and the bladder. it also lines the minor ducts of several glands.
section b 6th question option a : Lysosomes digest or damage their own cells by their enzymes, which lead to cell death. Absence of lysosomes leads to the cell start breakdown automatically. Bacteria like microbe can enter into the cell and spoil it snd If there are lysosomes they can digest the microbe that attract our body.
section b 6th question option b: The vacuole plays an important role in the homeostasis of the plant cell. It is involved in the control of cell volume and cell turgor; the regulation of cytoplasmic ions and pH; the storage of amino acids, sugars, and CO2; and the sequestration of toxic ions and xenobiotics
