Flashcard #1 \n**Term:** Lipid Bilayer \n**Definition:** A double layer of phospholipids that forms the basic structure of cell membranes, creating a barrier to the passage of ions and molecules.

**Flashcard #2** \n**Term:** Lysosome \n**Definition:** An organelle containing enzymes that break down waste materials and cellular debris.

**Flashcard #3** \n**Term:** Microtubules \n**Definition:** Cylindrical structures that are part of the cytoskeleton, providing support and shaping the cell.

**Flashcard #4** \n**Term:** Microfilaments \n**Definition:** Thin filaments in the cytoskeleton that aid in cellular movement and shape.

**Flashcard #5** \n**Term:** Vacuole \n**Definition:** A storage organelle in cells, often holding water, nutrients, or waste products.

**Flashcard #6** \n**Term:** Aquaporin \n**Definition:** A protein that facilitates the transport of water across cell membranes.

**Flashcard #7** \n**Term:** Endocytosis \n**Definition:** The process by which cells internalize substances from their environment.

**Flashcard #8** \n**Term:** Hypertonic \n**Definition:** A solution with a higher concentration of solutes compared to the inside of the cell, causing cells to lose water.

**Flashcard #9** \n**Term:** Isotonic \n**Definition:** A solution with the same concentration of solutes as the cell, resulting in no net movement of water.

**Flashcard #10** \n**Term:** Phagocytosis \n**Definition:** The process by which a cell engulfs solid particles, incorporating them into vesicles.

**Flashcard #11** \n**Term:** Receptors \n**Definition:** Proteins on cell membranes that bind to specific molecules, enabling cells to communicate and respond to their environment.
