Basics
Both _________ & _________characterize scientific culture.
Collaboration & Competition
Name one of the things in plant cells but not in animal cells.
Cell wall
Chloroplasts
Vacuole
This network of membranes is involved in protein and lipid synthesis; it's rough if ribosomes are attached.
Endoplasmic Reticulum
This type of filament is responsible for cytokinesis and cell crawling and can polymerize and depolymerize.
actin microfilaments
In this type of solution, a cell experiences no net change in water movement, maintaining its shape and size.
isotonic solution
Chemical reactions require chemical energy in what form?
ATP
Name the four macromolecules
Nucleic Acids
Carbohydrates
Proteins
Lipids
This organelle contains digestive enzymes that break down waste materials and cellular debris.
Lysosomes
These cytoskeletal structures maintain cell shape, anchor the nucleus, and are more solid, resembling ropes.
intermediate filaments
These are the three broad classes of transmembrane transport proteins that facilitate the movement of substances across the cell membrane.
Channels, Carriers, Pumps
Prokaryotes include what two groups?
Bacteria & Archaea
Name one of the things in animal cells but not plant cells.
Centrioles
Lysosomes
This organelle contains enzymes that detoxify harmful substances and break down fatty acids, producing hydrogen peroxide as a byproduct.
Peroxisomes
This organizing center is where microtubules originate and contains centrioles oriented at 90 degrees to each other.
centrosome
This special type of diffusion involves the movement of water across a selectively permeable membrane, from an area of low solute concentration to an area of high solute concentration.
Osmosis
Name one of the 3 Theories of Modern Biological Science
Cell Theory
Theory of Evolution by Natural Selection
Chromosome Theory of Inheritance
TEM & SEM
This organelle stores water, nutrients, and waste products in plant cells, often taking up most of the cell's volume.
Vacuole
These hollow tubes are composed of alpha and beta tubulin dimers and are involved in moving chromosomes by building at one end and falling apart at the other.
microtubules
In this type of solution, a cell will shrink because water moves out of the vesicle due to a higher solute concentration outside.
hypertonic solution
What is the broadest phylogenetic classification?
Domain
Describe a prokaryotic chromosome & where it can be found in a prokaryotic cell.
Prokaryotic chromosomes are singular, circular, & supercoiled. They are kept in the nucleoid region.
This organelle functions as the cell's "shipping center," modifying, sorting, and packaging proteins and lipids for delivery to their destinations.
Golgi Apparatus
This special motor protein "walks" along microtubule tracks from the negative to the positive end, with each step requiring energy from ATP hydrolysis.
kinesin
These specialized channel proteins allow water to move across the membrane, enhancing the process of osmosis.
Aquaporins
