(T/F) Does the Animal cell have Vacuole, Chloroplasts, Perixosome and Cell Wall?
False, The Plant Cell has those four.
(Identification) Enclosed by a ____________ which defines their boundaries.
Membrane
Composed of a Phospholipid Bilayer and Protein
Plasma Membrane
(identification) Polar - Loves Water
Hydrophilic
(identification) Non-Polar - Hates Water
Hydrophobic
(identification) Embedded in lipid bilayer - serve as “ion pumps”
Integral Proteins
Bound to membrane surface by ionic bonds and interacts with components of the Cytoskeleton
Peripheral proteins
(identification) Bound to surface via Lipid molecules
Anchored proteins
(identification) Contains almost all the genetic material
Nucleus
(identification) Allows the passage of macromolecules and ribosomal subunits in and out of the nucleus
Nuclear Pores
(T/F) Rough ER synthesize, process, and sort proteins targeted to membranes, vacuoles, or the secretory pathway.
True
(T/F) Smooth ER - Synthesize lipids and oils.
True
(identification) Modifies proteins and lipids from ER, sorts them and packages them into Transport Vesicles.
Golgi Network
(identification) Modifies proteins and lipids from ER, sorts them and packages them into Transport Vesicles.
Golgi Network
(identification) Golgi is fused with ________ membrane
Plasma
(T/F) In human and animal cells, the cleavage furrow starts at the inside?
False, outside.
(T/F) In plants, the Cell plate starts outside?
False, inside.
(identification) The ________ contains their own DNA and protein-synthesizing machinery.
Mitochondria
(T/F) The Mitochondria is thought to have evolved from Endosymbiotic Bacteria.
True
(identification) Cellular Respiration has three stages.
Glycolysis, Krebs Cycle, Electron transport.
(identification) Also contain their own DNA and protein-synthesizing machinery.
The Chloroplast
(T/F) The chloroplasts divides by Fusion.
True
(identification) 3rd membrane system.
Thylakoids
(identification) Stack of Thylakoids
Granum
(identification) The _______ can be 80-90% of the plant cell.
Vacuole
(identification) The Vacuole can be _________ of the plant cell.
80%-90%

(identification) 13 rows of tubulin = __ microtubules
1
(identification) Plasmodesmata contains a tube called ______________, which is a part of the ER.
Desmotubule
(identification) This is what connects adjacent cell and allow chemical communication and transport of material throughout the whole plant.
Plasmodesmata or Desmotubule
The Plant Cell Wall:
(identification) Cell walls are held together by the ___________.
Middle Lamella
(T/F) The plant cell walls is made up of: Cellulose, Xyloglucan, Pectin, Proteins, Ca ions(?), Lignin, Other ions, and Water.
True
