Organelles Galore
This organelle is responsible for packaging and sorting proteins for secretion.
What is the Golgi apparatus?
This lipid bilayer structure regulates the movement of substances into and out of the cell.
What is the plasma membrane?
This passive transport process involves the movement of water molecules across a selectively permeable membrane.
What is osmosis?
This term refers to the relative concentration of solute particles inside versus outside the cell.
What is tonicity?
Category: Cellular Processes
This cellular transport process involves the uptake of extracellular fluid and/or dissolved solutes by the cell.
What is pinocytosis?
This double-membraned organelle is the powerhouse of the cell, producing ATP through cellular respiration.
What is the mitochondria?
These proteins embedded within the plasma membrane help transport specific molecules across the membrane.
What are transport proteins?
This type of transport requires energy to move molecules against their concentration gradient.
What is active transport?
In this type of solution, the concentration of solutes outside he cell is higher than inside causing water to move into the cell.
What is a hypertonic solution?
This organelle is composed of a network of membranous tubules and sacs and plays a key role in lipid synthesis and detoxification.
What is the smooth endoplasmic reticulum?
This structure helps to stabilize the plasma membrane and regulate its fluidity, especially in extreme temperatures.
What are cholesterol molecules?
This transport process involves the movement of substances across the plasma membrane without the use of energy, relying on concentration gradients.
When a cell is placed in a hypotonic solution, this happens to its volume?
What is it increases/swells/crenation?
The spherical organelle contains enzymes and is involved in breaking down waste materials and cellular debris.
What is a lysosome?
These carbohydrate chains attached to proteins and lipids on the extracellular surface of the plasma membrane play a role in cell recognition.
What are glycoproteins and glycolipids?
This specific type of passive transport involves the movement of molecules from an area of high concentration to an area of low concentration until equilibrium is reached via a channel protein.
What is facilitated diffusion?
In this type of solution, the concentration of solutes outside the cell is lower than inside, causing water to move into the cell.
What is a hypotonic solution?
This organelle is responsible for producing components of ribosomes, essential for protein synthesis.
What is the nucleolus?
This process allows large molecules or particles to be engulfed by the plasma membrane and brought into the cell.
What is endocytosis? What is phagocytosis?
This type of transport involves the movement of large molecules out of the cell via vesicles that fuse with the plasma membrane.
What is exocytosis?
In an isotonic solution, this happens to the movement of water across the cell membrane.
What is it moves in and out equally, maintaining cell volume?
