Turner's syndrome - ✔✔congenital disorder caused by failure of the ovaries to respond to pituitary hormone stimulation; possible effects may include impaired intelligence, amenorrhea, and shortness of stature Lysosomes - ✔✔organelles that aid in the digestion of nutrients and other materials. Centrioles - ✔✔paired organelles that are found lying at a 90-degree angle near the nucleus. Golgi apparatus - ✔✔saclike membranous structure that sorts, modifies, and transports various proteins throughout the cell. endoplasmic reticulum - ✔✔a network of tubules through the nucleus and cytoplasm. Smooth muscle tissue - ✔✔muscle tissue is found in the viscera(internal organs). Involuntary tissue type controled by the autonomic nervous system. phagocytosis - ✔✔the cell engulfs a solid particle, such as bacteria. Electrolytes - ✔✔maintain voltages across cell membranes and carry electrical impulses across themselves and to other cells. Genetic engineering - ✔✔making or changing an organism's DNA. Epithelial tissue - ✔✔a flat arrangement of cells that forms the skin, lines and covers the organs, lines the walls of cavities, and forms tubes, ducts, and some glands. Connective tissue - ✔✔Most abundant tissue in the body. Supports organs, covers muscles, and connects muscles and bones. Cardiac muscle tissue - ✔✔muscle tissue is found only in the heart. Pinocytosis - ✔✔means the cell "drinks" the fluid required Nerve tissue - ✔✔has two properties: excitability and conductivity.
