Forms a boundary between a cell and the outside environment; controls the passage of materials into and out of a cell; selectively permeable.

Organelle that carry out the process of photosynthesis. They convert light energy and carbon dioxide into sugar molecules for plants.

Structure that contains genetic information (DNA) that is passed from one generation to the next.

Jellylike substance inside of cells that contains dissolved molecules such as proteins, nucleic acids, minerals, and ions; surrounds the organelles.

Membrane that surrounds the nucleus; it allows certain materials to enter and leave the cell.

Responsible for making proteins

Interconnected network of thin, folded membranes that transports proteins; contains ribosomes on the surface.

Organelles that contain enzymes to defend cells and break down damaged or worn-out cell parts.

Large, water-filled organelle that strengthens plant cells and helps to support the entire plant.

Cylinder-shaped organelles in animal cells that are made up of microtubules; they organize these microtubules during cell division.

A rigid outer layer in plant cells that gives protection, support, and shape to the cell.

“Brain” of the cell, controls, processes, and stores DNA

Dense structure in the center of the nucleus that starts ribosome production.

Interconnected network of thin, folded membranes that transports proteins; no ribosomes on the surface.

Stack of flat membrane-enclosed spaces that processes and sorts proteins.

A fluid-filled structure that is used to store materials needed by the cell.

Bean-shaped organelle that supplies the energy to a cell; the powerhouse of the cell

A flexible network of proteins that provides structural support for the cell.

Long, hollow tubes that give the cell its shape and are important during cell division.
