Homeostasis
True or False: Osmosis is an example of homeostasis at the cellular level
TRUE
What system do neurons belong to?
Nervous System
From smallest to biggest what is the cell hierarchy?
Atom, Molecule, Macromolecule, Organelle, Cell, Tissue, Organ, Organ system, Organism
Where does photosynthesis and cellular respiration happen?
Photosynthesis occurs in chloroplasts
Cellular respiration occurs in the mitochondria
List the 4 macromolecules
Lipids, Nucleic acids, Carbohydrates, Proteins
What is the Definition of Homeostasis?
The ability of the body to maintain a stable internal environment.
The digestive system is responsible for breaking down food in order to obtain nutrients. What other body system helps get nutrients throughout the body.
Circulatory system.
I am the food producer of plants I get energy from the sun and create sugars in order to break them down into energy. I am a ____________________
Chloroplast
What is the main goal for cellular respiration?
The main purpose is to create ATP (energy).
What are the elements found in Proteins?
Carbon, Hydrogen, Nitrogen, and Oxygen
What are 3 examples of negative feedback
What are the three main vessels within the circulatory system
Arteries, Capillaries, and veins
Ribosomes, DNA, Cell membrane, cytoplasm
Write the equation for cellular respiration on the board
Bonus points for correct balanced chemical equation
True or False: Checkpoints are necessary within the cell cycle and mitosis
Bonus points for explaining why
True
Because we need these checkpoints to check for any mutations before the cell divides. If there are no checkpoints the cell could continue to divide resulting in uncontrolled cell division
Give me one example of negative feedback and explain how that process maintains homeostasis.
Answers will vary
Name two places within the body where BOTH chemical and mechanical digestion occur.
Mouth and Stomach
OR
Stomach and Small intestine
What are the main functions for the following organelles
Vacuole, Cell Membrane, and Ribosomes
Vacuole - Stores water and food (larger in plants)
Cell membrane - Controls what goes in and out of cell
Ribosome - Create proteins
What are the Reactants for Photosynthesis?
CO2 + H2O + Sunlight Energy
What is the final outcome of cell division (Mitosis)
Two new daughter cells are created with identical DNA
What is the difference between Negative and Positive feedback?
The difference is that Negative feedback brings a system closer to stability while positive feedback works to increase the reaction due to increase in stimulus.
Difference between Chemical and Mechanical digestion
The difference between chemical and mechanical is that mechanical involves the breaking down of materials physically while chemical digestion breaks down food particles using, acids, bile, and enzymes
Name 5 organelles that plant and animal cells have in common
The plant will not be able to perform photosynthesis meaning it cannot create glucose. Because of this the plant will not be able to perform cellular respiration as well to create energy. The plant would eventually die.
Name the 4 phases of mitosis in order
Bonus points for naming the other two phases
Interphase, prophase, metaphase, anaphase, telophase, Cytokinesis
