Cell Structure & Function
Eukaryotic organisms have membrane-bound organelles. Which of these organelles is considered the "control center" and stores the genetic material for the cell?
The nucleus.
Which term best describes the type of cell division in which parent cells produce daughter cells with the same number of chromosomes as the parent cells?
What is Mitosis
Which process moves molecules other than water from an area of high concentration to low concentration?
What is Diffusion?
Ribosomes, endoplasmic reticulum, golgi apparatus and the nucleus. All of these organelles are involved in what process?
What is Protein Synthesis
The crab Lybia tessellata carries a pair of sea anemones on its claws. The crab uses the sea anemone’s stinging tentacles as protection and the sea anemone obtains small food particles released by the crab as it feeds. Which type of symbiotic relationship does this best illustrate?
What is mutualism
Placing wilted lettuce in cold water will make it crisp again. Which statement best describes what happens to restore the lettuce to its original condition? A Water left the lettuce cells by diffusion. B Water entered the cells of the lettuce by osmosis. C Osmosis caused salts to enter the lettuce cells. D Salts in the leaf caused water to leave the cells.
What is B-Water entered the cells of the lettuce by osmosis.
This process occurs in the nucleus and produces a molecule of mRNA
What is Transcription
If a raisin is placed in this solution it will take on water and grow larger. Name the solution.
What is a Hypotonic solution?
In which way are photosynthesis and cellular respiration different? A Cellular respiration stores ATP, while photosynthesis releases ATP. B Cellular respiration produces oxygen, while photosynthesis uses oxygen. C Photosynthesis releases energy, while cellular respiration stores energy. D Photosynthesis uses carbon dioxide, while cellular respiration produces carbon dioxide.
What is-D
The relationship that explains as predators increase, the prey will decrease - this will be followed by an increase in prey and a decrease in predator and the cycle will continue
What is Predator-Prey relationship?
This organelle is the site of aerobic cellular respiration in eukaryotic cells.
What is Mitochondrion

What is 10%
Predict what may occur if a cell skips the S phase?
Error in mitosis. Too little DNA for daughter cells. Daughter cells not identical.
A diploid cell contains 2 pairs of homologous chromosomes Ss and Tt. Due to independent assortment what is the possible genetic make-up of the gametes produced by this organism? A SsTt B Ss, Tt C S, s, T, t D ST, St, sT, st
