Question

question 13 1 pts the structure that separates the contents of a cell from the surrounding tissue is known as: golgi apparatus. plasma membrane. cytoplasm. centrosome. question 14 1 pts tiny indentations of the plasma membrane that resemble caves are called: mitochondria. caveolae. cisternae. vesicles. question 15 1 pts the inner membrane of what double - membrane structure is contorted into folds called cristae? golgi apparatus mitochondrion endoplasmic reticulum ribosome

Explanation:

• Question 13: The plasma membrane is the structure that separates the cell's contents from the surrounding tissue. It controls the movement of substances in and out of the cell.
• Question 14: Caveolae are tiny indentations of the plasma membrane that resemble caves and play roles in endocytosis and signal - transduction.
• Question 15: The inner membrane of the mitochondrion is contorted into folds called cristae, which increase the surface area for ATP - generating reactions.

Answer:

Question 13: plasma membrane
Question 14: caveolae
Question 15: Mitochondrion
