Major cell parts
The dynamic network of protein fibers that extends throughout the cytoplasm.
what is the cytoskeleton?
The cell part that houses genetic material and directs cell activities
What is the Nucleus?
a tiny, specialized structure inside a cell that performs a specific job
What is a organelle
When small molecules slip through the lipid layer
what is Diffusion
an active transport process where a cell surrounds extracellular material with its plasma membrane, folds inward, and pinches off to form a vesicle inside the cell
what is endocytosis
A double-membrane barrier that surrounds and protects the nucleus
Nuclear envelope
Stores energy as ATP and houses biochemical reactions that extract energy from the nucleus?
What is the mitochondria?
What are ribosomes?
Larger molecules cross using helper protein channels.
What is Facilitated Diffusion?
the cellular process where a cell uses its outer membrane to surround, engulf, and digest large particles.
What is phagocytosis?
The thin, flexible outer skin that surrounds the cell and controls what comes in and out.
What is the Cell Membrane?
The cell part that refines, packages, and transports proteins synthesized by ribosomes on the rough ER.
What is the Golgi apparatus?
this organelle builds cilia and flagella while also being responsible for cell division.
What are Centrioles?
Water molecules move across a semipermeable membrane.
What is Osmosis?
a cellular process where a cell engulfs extracellular fluid and dissolved small molecules by folding its membrane inward to form tiny, fluid-filled vesicles
What is piocytosis
The gel-like fluid that fills the inside of cells and holds all the inner parts
What is the cytoplasm?
The organelle that synthesizes lipids and phospholipids.
What is the smooth ER
This organelle is responsible for the digestive system of the cell and often disposes of waste.
What are Lysosomes?
Carrier proteins force ions against the gradient.
What is active Transport?
A dense membrane-free structure inside the nucleus that makes ribosomes
What is the nucleolus?
The organelle that synthesizes, folds, and quality checks protiens?
House enzymes, Catalyze (speed) a variety of chemical reactions, break down hydrogen peroxide (a by-product of metabolism) and fatty acids and detoxify alcohol
What are Peroxisomes
Vesicles fuse with the membrane to push materials out of the cell.
What is Exocytosis?
