|
Plasma membrane.
|
Prevents escape of cell contents; regulates exchange of materials between cytoplasm and extracellular fluid; involved in intercellular communication.
|
|
|
Microvilli.
|
Increase absorptive surface area; widespread sensory roles (hearing, equilibrium, taste).
|
|
|
Cilia.
|
Move substances along cell surface; widespread sensory roles (hearing, equilibrium, smell, vision).
|
|
|
Flagellum.
|
Sperm motility.
|
|
|
Nucleus.
|
Genetic control center of the cell; directs protein synthesis; shelters the DNA.
|
|
|
Rough ER.
|
Protein synthesis and manufacture of cellular membrane.
|
|
|
Smooth ER.
|
Lipid synthesis, detoxification, calcium storage.
|
|
|
Ribosomes.
|
Interpret the genetic code and synthesize polypeptides.
|
|
|
Golgi complex.
|
Receives and modifies newly synthesized polypeptides, synthesizes carbohydrates, adds carbohydrates to glycoproteins; packages cell products into Golgi vesicles.
|
|
|
Golgi vesicles.
|
Become excretory vesicles and carry cell products to apical surface for exocytosis, or become lysosomes.
|
|
|
Lysosomes.
|
Contain enzymes for intracellular digestion, autophagy, programmed cell death, and glucose mobilization.
|
|
|
Peroxisomes.
|
Contain enzymes for detoxification of free radicals, alcohol, and other drugs; oxidize fatty acids.
|
|
|
Mitochondria.
|
ATP synthesis.
|
|
|
Centrioles.
|
Form mitotic spindle during cell division; unpaired centrioles form basal bodies of cilia and flagella.
|
|
|
Centrosome.
|
Organizing center for formation of microtubules of cytoskeleton and mitotic spindle.
|
|
|
Basal body.
|
Point of origin, growth, and anchorage of a cilium or flagellum; produces axoneme.
|
|
|
Microfilaments.
|
Support microvilli and plasma membrane; involved in muscle contraction and other cell motility, endocytosis, and cell division.
|
|
|
Intermediate microfilaments.
|
Give shape and physical support to cell; anchor cells to each other and to extracellular material; compartmentalize cell contents.
|
|
|
Microtubules.
|
Form axonemes of cilia and flagella, centrioles, basal bodies, and mitotic spindles; enable motility of cell parts; form trackways that direct organelles and macromolecules to their destinations within a cell.
|
|
|
Inclusions.
|
Storage products or other products of cellular metabolism, or foreign matter retained in cytoplasm.
