Eukaryotic Cells
Does a Eukaryotic cell have a nucleus? If so name the 3 parts.
Yes. Nuclear Envelope, Nucleolus, Chromatin
What Domains contain Prokaryotic cells?
Bacteria and Archea
What organelles are in the endomembrane system?
the nuclear envelope, the endoplasmic reticulum, the Golgi apparatus, lysosomes, various kinds of vesicles and vacuoles, and the plasma membrane.
Is a plant cell Eukaryotic or Prokaryotic?
Eukaryotic
What protein produces microtubules?
tubulin
What is the difference between the rough ER and the smooth ER?
The rough ER has ribosomes on it and its role is to synthesize proteins. The smooth ER does not have ribosomes and its role is to synthesize lipids (lipid metabolism) and other HYDROPHOBIC molecules.
Do Prokaryotic cells have a cell wall? If so what is the function of the cell wall? What is it made of?
Yes! Gives the cell shape and protection. Made of Peptidoglycan.
What is the function of the Golgi Apparatus? What are the two sides of the Golgi Apparatus called and what are their functions?
to modify, store, and route products of the endoplasmic reticulum and synthesize some products, notably noncellulose carbohydrates. The Cis side receives from the rough ER and the trans side pinches off the vesicles and ships them off to the next site.
What is the cell wall of a plant made of?
Cellulose
What is the difference between flagella and cilia?
Flagella spins while cilia beats back and forth ( cilia is found in lungs example)
Does a Eukaryotic cell have a cell wall?
No, it only has a cell membrane
Do Prokaryotic cells have a nucleus? If not what do they have?
No, they have a nucleoid
Function of lysosomes? How does phagocytosis aid lysosomes?
A lysosome is a membranous sac of hydrolytic enzymes that many eukaryotic cells use to digest (hydrolyze) macromolecules. Phagocytosis "brings the trash in" by engulfing the particle and giving it to the lysosome.
What is a special feature that only a plant cell has and what is its function?
Chloroplast. It drives photosynthesis by converting sunlight into sugar for the plant to utilize. Central vacuole, a large membranous sac with diverse roles in growth, storage, and sequestration of toxic substances.
What is the structural role of microfilaments in the cytoskeleton? 2 main microfilaments
To withstand tension. Actin and myosin.
Where are ribosomes found in an Eukaryotic cell? What is their measurements?
They are found free in the cytosol and in the Rough Endoplasmic Reticulum. 80S.
Name of the propeller that helps bacteria move through aqueous solution
Flagella
What is the function of a motor protein?
it interacts with cytoskeletal elements and other cell components, producing movement of the whole cell or parts of the cell.
What is the function of the Plasmodesmata?
they are cytoplasmic channels through cell walls that connect the cytoplasm of adjacent cells.
What is the most abundant glycoprotein in an animal cell? Where is this glycoprotein embedded?
collagen, proteoglycan
What is the function of the mitochondria? Does it require anaerobic or aerobic conditions? How many membranes does it have? Which membrane is folded? What is special about the mitochondria?
Site of energy and metabolism and cellular respiration. It requires aerobic conditions to make ATP. It has 2 membranes and the inner membrane is highly folded. It special because it has its own DNA separate from the nucleus.
Measurement of a Prokaryotic Ribosome
70 S
Where do microtubules grow out from?
Centrosome
What components make up the cytoskeleton of a plant cell?
Microfilaments and Microtubules
Which structure is common to plant and animal cells?
chloroplast
wall made of cellulose
mitochondrion
centriole
