TEAS Test: Science Questions With
Answers
All cells carry out the basic process of life: - Answer - *Take in food and metabolize it for energy
*Respond to the environment
*GROW
*ReproduceReproduceReproduce
*Get rid of waste
Prokaryotes (Cell) - Answer - *Single Cell
* Bacteria, Algae
*Extremely small cells
*NO nucleus or organelles
*Single, usually circular chromosome
*Reproduce by FISSION (budding)
Eukaryotes (Cell)
YOU-karyote - Answer - *Single-Celled AND multicelled
*Plants, animals, fungi, and protists5
*LARRRGE cells (10x as large as prokaryotes)
*Nucleus and organelles
*Multiple chromosomes
*Mitosis and Meiosis for growth & reproduction
Serial Dilution of Bacteria - Answer - *Is a process that is used to estimate bacteria populations
*Can be useful for many environmental, health & commercial purposes
, Process of Serial Dilution - Answer - *In serial dilution, a sample is repeatedly diluted
*1ml is taken out of the flask & put into the first tube with 9ml of water, representing a 0.1 or 10-1
dilution
*The process is repeated 3 more times
Eukaryotes have organelles which are... - Answer - *Specialized membrane-bound structures.
*Note-prokaryotes don't have organelles!
Chloroplast - Answer - *What it does? Site of photosynthesis
*Who has it? Eukaryote plant cells
Nucleus - Answer - *What it does? It regulates activity all cell activity; including reproduction (does this
through DNA, which codes for enzymes that carry out all important cell 'jobs')
*Who has it? ALL Eukaryote cells
Ribosomes - Answer - *What it does? Use RNA to transcribe the original DNA code into proteins
*Who has it? Eukaryote & prokaryotes
Mitochondria - Answer - *What it does? Cell Powerhouse; use oxygen to burn glucose & produce ATP
for cell energy
*Who has it? ALL Eukaryotes
Cytoplasm - Answer - *What it does? Watery medium inside of the cell
*Who has it? All Eukaryotes & prokaryotes
Cytoskeleton - Answer - *What it does? Provides structure for cell & allows transport
Who has it? ALL Eukaryotes
Endoplasmic
Reticulum
