4 Things All Cells Have in Common Flashcards

Study Notes

Characteristics Common to All Cells

Every cell possesses a cell membrane, functioning as a bilipid layer that encloses the cell's contents and regulates substance exchange.
DNA is present in all cells, serving as the blueprint for genetic information needed to produce RNA and proteins.
Ribosomes are found in every type of cell, playing a crucial role in synthesizing proteins, which are essential for cellular functions.
The cytoplasm is the intracellular fluid that contains enzymes to facilitate rapid chemical reactions essential for cell metabolism.

Cell Membrane

Composed of a bilayer of phospholipids, the cell membrane selectively allows substances to enter and exit, maintaining homeostasis.

DNA

DNA (deoxyribonucleic acid) carries genetic information necessary for the growth, development, and reproduction of organisms.

Ribosomes

Ribosomes can be found free-floating in the cytoplasm or attached to the endoplasmic reticulum and are integral to translating mRNA into protein structures.

Cytoplasm

The cytoplasm provides a medium for molecular movement and houses various organelles, contributing to the overall functionality of the cell.
