Cell Structure
Name one commonly occurring organelle
Nucleus, rough ER, golgi apparatus, lysosome, mitochondrion, free ribosomes, chloroplasts (in plant cells), vacuoles & vesicles, microtubules & centrioles, cilia & flagella
The compartments in the cytoplasm of a eukaryotic cell
Organelles
It protects the cell, maintains the shape and prevents it from bursting
What is the purpose of having a cell wall?
A prokaryotic cell
What is a cell with no nucleus?
This part of the cell is made up of a phospholipid bilayer and contains proteins and chromosomes
What is the plasma membrane?
The difference between a eukaryote and a prokaryote
Prokaryotes do not have a nucleus, eukaryotes do
Organelle that contains the DNA in eukaryotic cells. It is found in the nucleus.
What are chromosomes?
The region of the cell that contains the DNA in prokaryotes
What is the cytoplasm?
Where prokaryotes are found.
Everywhere
The methods of membrane transport
What are simple diffusion, facilitated diffusion, osmosis, and active transport?
The part of the cell that does not contain DNA.
What is the endoplasmic reticulum?
An intracellular double-membrane system to which ribosomes are attached to.
What is the endoplasmic reticulum?
The purpose of having a cell wall
It protects the cell, maintains the shape and prevents it from bursting
How prokaryotes divide.
What is binary fission?
The difference between endocytosis and exocytosis.
Endocytosis brings materials into the cells and exocytosis releases the materials in the cells.
The structure of a eukaryotic cell
What is compartmentalized?
These are structures projecting from the cell's surface.
What are cilia and flagella?
the function of the rough endoplasmic reticulum
Synthesizes proteins for secretion from the cell
What happens during binary fission.
The single circular chromosome is replicated, the two copies of the chromosome move to opposite sides of the cell and then divide.
The proteins found in the plasma membrane
What are integral proteins and peripheral proteins?
An advantage of being compartmentalized
What is enzymes and substrates can be more concentrated, OR, substances that could cause damage can be kept inside the membrane of an organelle, OR, conditions can be maintained at an ideal level, OR, organelles with their contents can be moved around within the cell?
Organelle that consists of flattened membrane sacs known as cisternae, these cisternae aren’t long and do not have ribosomes attached like a similar organelle
What is the golgi apparatus?
The function of the golgi apparatus
Processes proteins brought in vesicles from the rER
The size a prokaryote is measured in
What are Svedberg units?
The Davson-Danielli model.
A model of membrane structure based on electron microscopy and X-ray diffraction studies.
