Text Bank for Cells and Tissues

The text discusses various topics related to cells and tissues. The key points are: • Ribosomes are responsible for protein synthesis while the Golgi apparatus is responsible for packaging. Smooth muscle tissue is made up of nonstriated involuntary muscle cells. • Microvilli are tiny extensions of the plasma membrane that increase the area for absorption. Cilia and flagella actually move the cell. • Mitochondria are responsible for cellular respiration and ATP formation. The plasma membrane is bipolar with hydrophilic heads. • Macrophages have the most lysosomes. Simple squamous epithelia have cells that are flat and touch the basement membrane. • Osmosis is the movement of water across a membrane down its concentration gradient. Facilitated diffusion requires a protein membrane channel. • Anaphase is the phase of mitosis where chromosomes move to opposite sides. Tendons are a type of dense connective tissue. • Blood is a connective tissue. Exocytosis uses vesicles from the Golgi apparatus to transport substances across the cell membrane. • Cartilage and bone tissues contain lacunae. Exocrine glands release substances through ducts.
