Copy the table given below and then fill up the blanks. Underline the blanks. Structure Location / Function 1. Semilunar valves 2. Centrosomes 3. Amnion 4. Seminiferous tubules 5. Eustachian tube

Structure Location / Function 1. Semilunar valves Present at base of the aorta and pulmonary artery in the heart/ To prevent backflow of blood into the heart. 2. Centrosomes Present in cells and made of two centrioles / To pull apart the chromatids during cell division. 3. Amnion Present surrounding developing foetus / It is a thin, tough membrane that protects the developing child. 4. Seminiferous tubules Male testes / Site of production of sperms. 5. Eustachian tube Ear / Maintains the pressure in the middle ear. Semilunar valves are valves present in the heart that prevent the backflow of blood into the heart from the aorta and pulmonary artery. Centrosomes are made of two centrioles in eukaryotic cells that form structures with microtubules to pull apart chromatids during cell division. Amnion is a thin, tough membrane that encloses the developing child in the womb to protect it. Seminiferous tubules are present in the male testes and are involved in the production of male gametes. The Eustachian tube is present in the middle ear and is involved in regulating pressure in the ear.
