Chap 3 Test - Cells and Membranes Review

QuestionAnswer
Which organelle contains the green pigment chlorophyll? the chloroplast
Which organelle controls the cell with it's stored DNA? the nucleus
If a membrane allows only certain molecules to pass through, it is said to be what? selectively permeable
To determine the total magnification of a compound light microscope, multiply the ocular (10X) times the objective
Which early microscope inventor ground his own lenses? Anton Von Leewenhoek
The organelle that stores food, water, or wastes is the vacuole
The type of microscope with 2 sets of lenses is called the compound microscope
All cells have DNA, cell membranes, cytoplasm, and ribosomes
Plants cells make their own food with chloroplasts
What organelle do eukaryotes have that prokaryotes do not have? nucleus
Cellular respiration, the breakdown of sugar to release energy for the cell, takes place in the mitochondria
The enzymes that digest materials for an animal cell are contained in the lysosome
The network of folded membranes found in the cytoplasm that allows substances to move from one part of the cell to another are called the endoplasmic reticulum
Protein synthesis, the making of proteins, takes place in the ribosome
Substances to be released from the cell are refined and packed in the Golgi apparatus
Which are longer, cilia or flagella? flagella
The phospholipid hydrophobic tails are the interior or exterior portion of the cell membrane? interior
An example of prokaryotes would be the bacteria
Are all eukaryotes the same type of cell? no
The organelle made of microtubules and helps in cell reproduction is the centriole
To view a speciman with your microscope, you would look through the ocular lens
To adjust the amount of light passing through your specimen, you use the diaphragm
Which adjustment knob is used to find the specimen with a quick focus? coarse adj. knob
The movement of molecules from an area of high concentration to an area of low concentration is diffusion
The thick protein rich fluid of the cell is the cytoplasm
Moving materials through the cell membrane with the use of ATP (energy) is called active transport
When molecules pass through a selectively permeable membrane without the need of ATP (energy) is passive transport
The diffusion of water is called osmosis
