Lipid Bilayer

A double layer of phospholipids that forms the basic structure of cell membranes, creating a barrier to the passage of ions and molecules.

Lysosome

An organelle containing enzymes that break down waste materials and cellular debris.

Microtubules

Cylindrical structures that are part of the cytoskeleton, providing support and shaping the cell.

Microfilaments

Thin filaments in the cytoskeleton that aid in cellular movement and shape.

Vacuole

A storage organelle in cells, often holding water, nutrients, or waste products.

Aquaporin

A protein that facilitates the transport of water across cell membranes.

Endocytosis

The process by which cells internalize substances from their environment.

Hypertonic

A solution with a higher concentration of solutes compared to the inside of the cell, causing cells to lose water.

Isotonic

A solution with the same concentration of solutes as the cell, resulting in no net movement of water.

Phagocytosis

The process by which a cell engulfs solid particles, incorporating them into vesicles.

Receptors

Proteins on cell membranes that bind to specific molecules, enabling cells to communicate and respond to their environment.
