Matching Pairs Structures and FunctionsOnline version Match structures to functions by Gail Rosewood 1 Plasma membrane: Flexible and does not mix with water 2 Neurons: Long and branching, with receptor proteins on the outside 3 Cardiac muscle cells: Contain many mitochondria 4 Leukocyte: Can reach out with its cell membrane to capture invaders; contains many lysosomes (organelles filled with digestive enzymes) 5 Intestinal cell: Contains many transport proteins and has long finger-like structures called microvilli 6 Carbon atoms: Can bind to 4 other atoms 7 Nucleus: Contains the cell's DNA, separating it from the rest of the cell 8 Mitochondria: Full of ATP synthase, with lots of folds to increase surface area for chemical reactions Can break down captured invaders after it "eats" them to defend the body Can connect with many other cells all over the body to send signals between the body and the brain Makes sure the right proteins are made at the right time Separates the inside of the cell from the environment; changes shape to let nutrients in and wastes out Can absorb nutrients from outside the body and bring them inside the body Generate energy for the cell Constantly moving in order to pump blood through the body Form complex molecules
