100
Bacteria and archaea
Which domains are made up of prokaryotic cells?
200
Chloroplasts and cell wall.
Parts of a plant cell.
200
made of actin
What is a microfilament made up of?
200
Specialized type of pinocytosis that enables the cell to engulf specific substances.
What is receptor mediated endocytosis?
200
Diameter of molecules, temperature and concentration gradient.
What factors does diffusion depend on?
200
considered anchoring junctions.
Desmosomes.
300
DNA and cell membrane
All cells contain these.
300
only animal cells have it to compensate for lacking a cell wall. Helps with support, structure, protection and signaling.
What is the ECM (extracellular matrix)?
300
Reacts with integral proteins and are not embedded in the membrane.
What is a peripheral protein?
300
Protein channels that facilitate the passage of water molecules through the plasma membrane.
what are Aquaporins?
300
Nucleoplasm
What is the name of the region where chromatin is housed?
400
A large subunit 60s and small subunit 40s
80s of eukaryotic ribosomes are composed of?
400
epithelium, connective, muscle and nervous.
What are the 4 types of tissues?
400
A protein that generates voltage across the membrane
What is an electrogenic pump?
400
Active transport driven by a concentration gradient.
What is cotransport.
400
Ribosomal subunits, tRNA and mRNA
What can diffuse through the nuclear pores?
500
prokaryotic has 3, plant cells have 2 and an animal cell has 1.
how many membranes/layers does each cell have?
500
alpha tubulin and beta tubulin
what are microtubules made up of?
500
voltage across the membrane
What is a membrane potential?
500
A human cell will be lysed and a plant cell will be turgid
What would happen to cells in a hypotonic solution?
500
cells are pressed together preventing any leakage. One example is the urinary bladder
