Question
Answer
show 1.All organisms are composed of cells 2. 3. All cells come from preexisting cells  
🗑
show Small cells are likely to have an adequate surface area for exchanging wastes for nutrients. B. Cells that specialize in absorption have modifications that greatly increase the surface area per volume of the cell.  
🗑
prokaryotic   show
🗑
show Cell Envelopes plasma membrane cell wall glycocaly Capsule Cytoplasm Nucleoid Plasmid Inclusion Bodies Cyanobacteria Ribosomes Appendages Flagella Fimbriae Sex Pili  
🗑
show Contain membrane-bounded nucleus. Contain plasma membrane.  
🗑
show Compartmentalization:Allows eukaryotic cells to be larger than prokaryotic cells Isolates reactions from others B. Two classes: 1. Endomembrane system: Organelles that communicate with one another Energy related organelles Mitochondria & chloroplast  
🗑
show Prokaryotic cells: protein synthesis Eukaryotic cells:Composed of rRNA Consists of a large subunit and a small subunit Subunits made in nucleolus  
🗑
show Endoplasmic Reticulum Golgi Apparatus Lysosomes  
🗑
Energy-Related Organelles   show
🗑
show Both form vesicles that transport materials to the Golgi apparatus for modifications and packaging  
🗑
show Peroxisomes are membrane-bounded vesicles that enclose enzymes.  
🗑
vacuoles   show
🗑
show functions in storage of nutrients and waste products; provides support and is a reservoir for water  
🗑
show involved in cellular respiration Produce most of ATP utilized by the cell Cristae – Folds of inner membrane that encloses matrix. Matrix - Enzymes that break down nutrient molecules.  
🗑
List the 6 components of the cytoskeleton and the overall function of the cytoskeleton.   show
🗑
show Pseudopods b. Motor molecules  
🗑
show Supports nuclear envelope  
🗑
Microtubules   show
🗑
show are hairlike projections with a 9 + 2 pattern of microtubules that aid in cell movement. In eukaryotes, cilia are much shorter than flagella  
🗑
show organelle that is found at base of cilia and flagella and may direct organization of microtubules  
🗑
show 1.External surface and cytoplasmic surface lined with hydrophilic polar phosphate heads 2. Sandwiched in between are Nonpolar, hydrophobic, fatty-acid tails  
🗑
show 1. Modifies fluidity of membrane a stiffens membrane at higher temperatures b. at lower temperatures, helps prevent membrane from freezing by not allowing phospholipid tails to come in contact with each other 2. Lipid structure  
🗑
glycolipid   show
🗑
show carbohydrate chain attached to protein  
🗑
Describe the reason each cell has a unique “fingerprint”.   show
🗑
peripheral protein   show
🗑
integral protein   show
🗑
show Channel Proteins Carrier Proteins Cell Recognition Proteins Receptor Proteins Enzymatic Proteins Junction Proteins  
🗑
Channel Proteins   show
🗑
show Combine with substance to aid in passage through membrane.  
🗑
show Help body recognize foreign substances.  
🗑
show Carry out metabolic reactions directly  
🗑
show Only certain substances can move across the membrane and others cannot  
🗑
factors that determine whether a  molecule can pass through the plasma membrane of a cell   show
🗑
show Particles move from area of high concentration to an area of low concentration  
🗑
solution   show
🗑
show solid  
🗑
show liquid  
🗑
Describe the two methods of passive transport of materials across a membrane.   show
🗑
Osmosis   show
🗑
show is the pressure that develops due to osmosis  
🗑
Tonicity   show
🗑
Isotonic Solution   show
🗑
Hypotonic Solution   show
🗑
Cytolysis   show
🗑
show plant cells do not burst due to cell wall; provides water to allow plant to remain erect  
🗑
Hypertonic Solution   show
🗑
show animal cells shrivel  
🗑
Plasmolysis   show
🗑
Describe the two methods of active transport of materials across a membrane   show
🗑
exocytosis   show
🗑
show Cells engulf substances into pouch which becomes a vesicle  
🗑
show Large, solid material into vesicle  
🗑
Pinocytosis   show
🗑
Receptor-Mediated   show
🗑
extracellular matrix   show
🗑
show a. Collagen b. Elastin- gives resilience c. Fibronectin- binds to integrin and assist communication between ECM and cytoskeleton d. Proteoglycans- resists compression of ECM and assist cell signaling  
🗑
Adhesion Junctions (desmosomes)   show
🗑
show Form impermeable barriers  
🗑
show Plasma membrane channels are joined (allows communication)  
🗑
show Plants have freely permeable cell wall, with cellulose as the main component.  
🗑
plasmodesmata   show
🗑


   

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
 
To hide a column, click on the column name.
 
To hide the entire table, click on the "Hide All" button.
 
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
 
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
