Parts of the cell
Terms in this set (14)
Cell Membrane
The cell membrane provides mechanical support that facilities the shape of the cell while enclosing the cell and its components from the external environment.
Nucleus
The control center of the cell, containing DNA organized into chromosomes. It regulates gene expression, cell growth, and division.
Nucleolus
Located inside the nucleus, it synthesizes ribosomal RNA (rRNA) and assembles ribosome subunits
Ribosomes
Non-membranous organelles responsible for protein synthesis. They can be free in the cytoplasm or attached to the rough endoplasmic reticulum
Endoplasmic Reticulum Smooth
Lacks ribosomes; involved in lipid synthesis, detoxification, and calcium storage
Endoplasmic Reticulum Rough
Studded with ribosomes; synthesizes and processes proteins.
Golgi Apparatus
Modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles
Mitochondria
Known as the “powerhouse” of the cell, they generate ATP through cellular respiration and regulate energy metabolism
lysosomes
Contain digestive enzymes to break down macromolecules, old organelles, and pathogens
Peroxisomes
Detoxify harmful substances and metabolize fatty acids
Cytoskeleton
Composed of microfilaments, intermediate filaments, and microtubules; provides structural support, facilitates intracellular transport, and enables cell movement
Centrioles
Involved in organizing microtubules during cell division in animal cells
Vacuoles
Storage organelles for water, nutrients, and waste; large central vacuoles in plant cells maintain turgor pressure
Cilia and Flagella
Hair-like structures that aid in cell movement or the movement of substances across the cell surface
