Animal Cell Structure

Nucleus: Houses genetic material (DNA) and controls growth and division; regulates gene expression and the cell cycle.
Nucleolus: Site of ribosome biogenesis; synthesizes rRNA and assembles ribosomal components necessary for protein synthesis.
Nuclear Envelope: Double membrane structure protecting the nucleus; regulates substance exchange between nucleus and cytoplasm via nuclear pores.
Mitochondria: Powerhouse of the cell; generates ATP through oxidative phosphorylation and regulates apoptosis, essential for cellular metabolism.
Rough Endoplasmic Reticulum (Rough ER): Studded with ribosomes, it is crucial for the synthesis of membrane-bound and secretory proteins.
Smooth Endoplasmic Reticulum (Smooth ER): Involved in lipid synthesis, detoxification of drugs, and calcium storage and regulation.
Ribosomes: Complexes of rRNA and proteins; perform protein synthesis by translating mRNA into proteins.
Golgi Apparatus: Modifies, sorts, and packages proteins and lipids for secretion or transport, playing a key role in cellular trafficking.
Lysosomes: Contains digestive enzymes (hydrolases) for intracellular digestion and recycling of macromolecules, waste, and pathogens.
Peroxisomes: Breaks down fatty acids and detoxifies reactive oxygen species (ROS), crucial for lipid metabolism and neutralization of harmful substances.
Cytoplasm: Aqueous solution supporting organelles; the site for metabolic reactions and maintaining cellular structure.
Cytoskeleton: Composed of actin filaments and microtubules; provides structural support, assists in cell movement, division, and organelle positioning.
Centrosome: Organizes microtubules; plays a significant role in cell division, ensuring correct chromosome segregation during mitosis and meiosis.
Vesicles: Small membrane-bound carriers that transport materials within the cell, aiding in endocytosis and exocytosis for molecule secretion.
