Human Biology Lab Exam #1
Questions and Answers
Ribosomes - ANSWER-Protein synthesis
Mitochondrion - ANSWER-Cellular respiration
Golgi Apparatus - ANSWER-Organelle that separates proteins + lipids received from
the E.R.
Vesicle - ANSWER-Storage and transport of substances
Cytoplasm - ANSWER-Contents of the cell between the nucleus and plasma
membrane. (Gooey stuff)
Lysosome - ANSWER-Intracellular digestion
Organelle - ANSWER-Little organs of the cell
Hypertonic - ANSWER-When 1 of 2 solutions have a higher concentration of
dissolved material (LESS WATER) than the other solution. (WATER LEAVES THE
CELL)
Hypotonic - ANSWER-When 1 of 2 solutions has a lower concentration of dissolved
material (MORE WATER) than the other solution. (WATER GOES INTO THE CELL)
Which potato produced more bubbles paired with hydrogen peroxide in the catalase
experiment? - ANSWER-Macerated potatoes, because there was more surface area
Which potato produced less bubbles paired with hydrogren peroxide in the catalase
experiment? - ANSWER-The Cubed potato, because there was less surface area for
the hydrogen peroxide to take effect.
Potato + Hydrogen Peroxide + Distilled Water = - ANSWER-+++
The water's neutrality allowed the hydrogen peroxide to bubble the most.
Potato + HP + Lemon Juice - ANSWER-+
Lemon juice's acidity balanced out the enzyme, making the HP less effective
Potato + HP + Ammonia - ANSWER-++
Ammonia was only slightly less effective than the water in allowing the hydrogen
peroxide to bubble
What does "simple" mean in regards to epithelial tissue? - ANSWER-There is only 1
layer of cells
Stratified? - ANSWER-Cell layers are placed on top of each other
