Cell Test Review: (all decks combined) Flashcards
Which phase is known as the middle phase?
metaphase
Describe the activity of the centrioles during prophase
- Migrate to opposite poles of the cell.
- grow spindle fibers
Came up with the word cell
Robert Hooke
Two types of endocytosis
phagocytosis
pinocytosis
What returns during telophase?
- Nuclei
- Nucleoli
Three types of transport
Passive Transport
Active Transport
Movement of Macromolecules
attach to glycoproteins
Peripheral proteins
During which phase of the cell cycle does the nucleus divide into two?
M phase or mitosis
Microscope that coats the speciman with a metal. Electrons bounce off the speciman and produce and image
Scanning electron microscope
During which phase of the cell cycle does the cell split into two daughter cells?
C phase or cytokinesis
Diffusion through an integral protein from high to low concentration.
Facilitated diffusion
What are the products of lactic acid fermentation?
- Lactic acid
- 2 NAD+
During passive transport how do molecules move?
- From high to low concentration
- Down the conentration gradient.
How do chromosomes line up during metaphse?
In a single file line
What is the cytoplasm of the mitochondria called?
Matrix
Category of transport that does not require energy from the cell
Passive transport
What type of cells go through the cell cycle?
Somatic cell
or
diploid cells
During which phase of mitosis do the DNA molecules form chromosomes?
Prophase
Loss of osmotic pressure in an animal cell
crenation
Exploding of an animal cell
Lysing
Two types of electron microscopes
Scanning
and
Transmission
Electron Microscopes
Which organelle do spindle fibers grow out of?
centrioles
Which form of DNA is condensed?
Chromosome
Found inside of the nucleus. They synthesize the ribosomes
nucleolus
Organelles only in animal cells
Lysosomes
Cilia and Flagella
Cytoskeleton
Movement of water from high to low concentrations.
Osmosis
During osmosis water moves from a _______solution to a ___________ solution.
hypotonic to hypertonic
(TO THE HYPER!)
Concluded that all cells come from preexisting cells
Rudolf Virchow
Which products of glycolysis move on to the Krebs cycle?
Pyruvic acid
Part of the phospholipid that doesn’t like the solvent in the cytoplasm or the environment
Fatty Acid Tails
_______ releases large products or waste molecules out of the cell.
Exocytosis
Type of solution that is more concentrated than the other solution.
hypertonic solution
During which phase of mitosis does DNA turn into the chromatin form?
Telophase
Which form of DNA is long and thin?
Chromatin
carbohydrates that attach to hydrophillic heads in the membrane
glycolipids
Which molecules react with pyruvic acid during fermentation?
2 NADH
Type of solution that has more solute and less solvent
hypertonic
Type of solution that is more dilute than the other solution.
hypotonic solution
Component of cell walls
Cellulose
Concluded that all animals are made up of cells
Theodore Schwann
Where does the Krebs Cycle take place?
Matrix of the mitochondria
What are the products of alchoholic fermentation?
