Termini in questo insieme (20)
The control center of the cell containing DNA and responsible for regulating cellular activities.
Organelle that modifies, sorts, and packages proteins and lipids for transport.
Membrane system studded with ribosomes; synthesizes proteins for secretion or membrane insertion.
Membrane system without ribosomes; synthesizes lipids, detoxifies chemicals, and metabolizes carbohydrates.
Membranous sac containing digestive enzymes for breaking down food and recycling damaged cell parts.
Storage organelle for food, nutrients, water, or waste; large central vacuole is prominent in plant cells.
Site of cellular respiration producing ATP; has a double membrane with folded cristae.
Organelle in plant cells where photosynthesis occurs; contains chlorophyll and thylakoids.
Rigid structure made of cellulose providing support and protection to plant cells.
Phospholipid bilayer that regulates entry and exit of substances, maintaining cellular homeostasis.
Sites of protein synthesis; free ribosomes produce cytosolic proteins, bound ribosomes produce membrane or secreted proteins.
Organelles that break down fatty acids and detoxify harmful substances using hydrogen peroxide.
Network of protein fibers (microtubules, intermediate filaments, microfilaments) that provide shape, support, and movement.
Long, tail-like structures made of microtubules that enable cell movement.
Short, hair-like structures made of microtubules that move fluid or cells.
Region within the nucleus responsible for synthesizing ribosome subunits.
The hypothesis that mitochondria and chloroplasts originated from prokaryotic cells living symbiotically inside ancestral eukaryotic cells.
Large vacuole in plant cells that stores water and maintains turgor pressure.
Channels between plant cells that allow transport and communication of water and nutrients.
Network of glycoproteins like collagen outside animal cells providing structural support and communication.
