Cell Components and Functions
-
Cell Membrane: Semi-permeable barrier that surrounds the cell, regulating entrance and exit of substances.
-
Rough Endoplasmic Reticulum (RER): Network of membranes studded with ribosomes; involved in protein synthesis and processing.
-
Mitochondrion: Powerhouse of the cell; generates ATP through cellular respiration.
-
Golgi Apparatus: Stacks of membranes responsible for modifying, sorting, and packaging proteins and lipids for secretion or delivery to other organelles.
-
Lysosome: Membrane-bound organelles containing enzymes for digestion; plays a key role in waste disposal and recycling of cellular components.
-
Cilia: Short, hair-like structures that aid in cell movement and the movement of substances along the cell surface.
-
Chromatin: Material composed of DNA and proteins; packages DNA into a more compact structure and regulates gene expression.
-
Nucleus: The control center of the cell; houses DNA and is responsible for regulating cellular activities such as growth and reproduction.
-
Nucleolus: Dense region within the nucleus where ribosomal RNA (rRNA) is synthesized and assembled with proteins to form ribosomes.
-
Smooth Endoplasmic Reticulum (SER): Lacks ribosomes; involved in lipid synthesis, detoxification, and calcium ion storage.
-
Vesicle: Small membrane-bound sac that transports materials within the cell and to the cell membrane for secretion.
