Cell Organelles and Membrane Structure

A set of flashcards based on lecture notes covering the structure and function of cell organelles and the plasma membrane.

Organelles

Structures within a cell that perform specific functions.

Cytoplasm

Jelly-like material in the cell where organelles are suspended.

Nucleus

The control center of the cell that contains genetic material.

Plasma Membrane

Also known as the cell membrane, it regulates what enters and exits the cell.

Semipermeable

A property of the plasma membrane that allows only specific materials to enter or exit.

Phospholipid Bilayer

Structure of the plasma membrane composed of two layers of phospholipids.

Mitochondria

Organelles responsible for energy production in the cell.

Chloroplasts

Organelles found in plant cells that conduct photosynthesis.

Vacuoles

Storage organelles that hold various substances.

Ribosome

Molecular machines in the cell responsible for protein synthesis.

Lysosomes

Organelles that contain digestive enzymes to break down waste.

Golgi Body

The organelle involved in modifying, sorting, and packaging proteins.

Cytoplasmic Streaming

The movement of the cytoplasm within plant cells that can help distribute materials.
