The gel-like substance between the nucleus and cell membrane, containing organelles.

The liquid component of cytoplasm where organelles float, made of a complex solution.

Programmed cell death where cells self-destruct when aged.

Involves synthesis, waste elimination, metabolism, maintenance, motility, and storage.

A bilipid layer that controls substance movement in/out of cells.

Largest organelle that contains genetic material and controls cell activities.

Two lipid layers that surround the nucleus and contain nuclear pores.

Two layers of phospholipids forming the plasma membrane.

Genetic material contained in the nucleus, present as chromatin or chromosomes depending on cell division.

Proteins in the plasma membrane that aid in transport and signaling.

Molecule found in the nucleus, plays a crucial role in protein synthesis.

Hydrophobic: water-hating; Hydrophilic: water-loving; key in membrane structure.

Structure within the nucleus that manufactures ribosomes for protein synthesis.

Proteins that span the entire membrane, allowing molecule passage.

Proteins that recognize and bind to hormones/chemical messengers.

A membrane protein that transports sodium out and potassium into cells.
