Cell Organelles
Which organelle serves as the cell’s boundary from its environment and controls what goes in and out of the cell?
What is the Cell Membrane?
What term term describes the relatively constant internal physical conditions of an organism?
What type of cellular transport requires a cell to use energy?
What is active transport?
What is the main purpose of the Cell Cycle?
What is Growth and Repair?
Mitosis is the process of creating what?
What is two new daughter cells?
Which principle of cell theory best supports the idea that new cells will replace damaged cells in a scraped knee?
What is principle 3? All Cells come from pre-existing cells?
Which type of feedback mechanism intensifies a reaction to stimuli?
What is a positive feedback mechanism?
This process occurs when the cell uses energy to push something out from inside the cell.
What is Exocytosis?
What is a chromosome called that has been through S-Phase of Interphase?
What is a Sister Chromatid?
What disappears in prophase but reappears in telophase?
What is the nuclear membrane?
What is an organelle you may expect to find in a plant cell but not in an animal cell?
What is a Chloroplast?
Central Vacuole and Cell Wall would also work.
What type of feedback mechanisms is maintained when heart beat is reduced to a normal BPM after a spike during exercise?
What is a Negative Feedback loop?
What type of osmotic solution has equal concentrations of solution inside and outside of the cell?
What is Isotonic?
In what stage of Mitosis does cytokinesis begin?
What is telophase?
The centrioles release what which helps with placement of the chromosomes during mitosis?
What is Spindle Fibers?
What is the difference between the rough ER and the smooth ER?
The rough ER contains ribosomes and creates proteins, while the smooth ER has no ribosomes and makes lipids.
A student walks to school in the morning when the outside temperature is 60°F. When the same student walks home after school, the outside temperature has dropped to 35°F. In this situation, how is thermal homeostasis maintained?
What is a positive feedback loop of shivering?
What type of transport would the following scenario be described as:
When a white blood cell captures bacteria.
What is Endocytosis?
In which stage of the cell cycle is the focus on growth and DNA synthesis?
What is interphase?
What happens with sister chromatids during metaphase?
They are lined up in the middle.
What organelle would be considered the most important? (Think of which organelle all others work to support).
What is Ribosomes?
Students in a class are designing an investigation to determine the effect running on a treadmill has on heart rate. They decide to have several students run for 20 minutes on a treadmill.
Which two data sets must the students collect in order to determine the effect exercise has on heart rate?
What are the resting heart rate and heart rate after exercise?
If an animal cell were placed in a solution of salt water taken from the ocean, what would happen to the cell? (Think about our gummy bear in salt water).
The cell would shrivel due to it being a hypertonic solution.
What process is used to prevent mistakes in the cell cycle due to increased cell division?
What is apoptosis?
What two things must occur for a cell to move from Metaphase to Anaphase?
The sister chromatids must be separated, and move to opposite sides of the cell.
