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.
