Cells
All living organisms are made of one or more ______
What are cells
Site of lipid synthesis in eukaryotic cell
What is the smooth endoplasmic reticulum (smooth ER)
Movement of a substance from a high to low concentration
What is diffusion (passive transport)
In a hypotonic (freshwater) environment, a cell will _____
What is swell up
In active transport, substance move ___________
What is from a low to high concentration
What are pre-existing cells
Vesicle that contains digestive enzymes
What is a lysosome
Molecules that can pass through the phospholipid bilayer without a protein channel (by simple diffusion)
What are O2 and CO2
In a hypertonic (high solute) environment, a cell will _____
What is shrivel up
In active transport, the addition of energy is _____
What is energy is required
Cells that tend to be smaller, have no nucleus, and no membrane-bound organelles are ______________
What are prokaryotic cells (bacteria and archaea)
Site of ribosomal RNA transcription in a nucleus
What is the nucleolus
For diffusion (passive transport), the addition of energy is
What is not required
Cells with a cell wall in a hypertonic environment experience _____________
What is plasmolysis
The ion that is actively transported across the inner membrane of the mitochondria (cellular respiration) and the thylakoid membrane (photosynthesis)
What is H+ (hydrogen ions, or protons)
Cells that have linear chromosomes with telomere ends that are wrapped around core histone proteins are _____
What are eukaryotic cells
Site of synthesis of transmembrane proteins or secreted proteins
What is the rough endoplasmic reticulum (rough ER)
The structure that separates the interior of the cell from the external environment is the
What is the plasma membrane (cell membrane)
Cells without a cell wall in a hypotonic environment (freshwater) may experience this.
What is osmotic lysis (cytolysis)
A small enclosed membrane that travels through a eukaryotic cell along microtubules (such as from the rough ER to the Golgi)
What is a vessicle
Cells that have a plasma membrane, enzymes, DNA, RNA, and ribosomes
What are all types of living cells
Site of packaging, processing, and modifying of proteins from the rough ER
What is the Golgi apparatus
This rigid structure can maintain cell shape, provide mechanical protection, and resist osmotic lysis in hypotonic environments
What is a cell wall
Cells with a cell wall in a hypotonic environment become this
What is turgid (undergoing turgor pressure)
This happens when a vesicle from the Golgi apparatus secretes proteins outside the cell
What is exocytosis
