Definition: The plasmalemma is a thin layer that surrounds a cell, also known as the cell membrane, which controls what enters and leaves the cell.

Example: The plasmalemma plays a crucial role in maintaining the cell's environment.

Definition: A medical procedure that involves removing plasma from a person's blood and returning the other parts, like red blood cells, back to them.

Example: The doctor recommended plasmapheresis to help treat the patient's autoimmune disorder.

Definition: A type of cytoplasm that is more fluid than a gel-like state, often found in certain cells like amoebas.

Example: The plasmasol allows the amoeba to move and change shape easily.

Definition: Relating to or having the qualities of plasma, which is a state of matter similar to gas but with charged particles.

Example: The scientist studied the plasmatic properties of the new material.

Definition: Relating to or connected with a substance that is similar to a liquid but can also have properties of a gas or solid, often found in biological contexts.

Example: The scientist studied the plasmic properties of the cell's interior.

Definition: A small, circular piece of DNA that can replicate independently inside a cell, often found in bacteria and used in genetic research to move genes between cells.

Example: Scientists use plasmids to insert new genes into bacteria for research purposes.

Definition: A type of enzyme in the blood that helps break down blood clots by dissolving fibrin, which is a protein that forms the structure of clots.

Example: Plasmin plays a crucial role in the process of healing by breaking down clots after they are no longer needed.

Definition: A substance in the body that is inactive until it is converted into plasmin, which helps break down blood clots.

Example: Plasminogen is essential for the process of clot breakdown in the body.

Definition: A thin strand of cytoplasm that connects the living parts of adjacent plant cells through small openings in their cell walls.

Example: Plasmodesmata allow for the transport of nutrients and signals between plant cells.

Definition: A type of organism that can be a parasite causing malaria or a stage in the life cycle of slime molds, characterized by a mass of cytoplasm with multiple nuclei.

Example: The doctor explained that plasmodium is responsible for the spread of malaria in tropical regions.
