Equilibrium, balance in and out of the cell. Sweating when it's hot outside, shivering when you're cold.
What is homestasis?
100
The cell must use this to move molecules from low concentration to high concentration.
What is energy?
100
Molecules that mix with water, like salt and sugar.
What is a solute?
100
This was the solute in our lab demonstration.
What is salt or sugar.
200
This is where we describe what we learned in our experiment and explained if the hypothesis was correct or incorrect.
What is a conclusion?
200
Feature of the cell membrane that means it only lets certain molecules/particles in and only certain molecules/particles out.
What is semi-permeable?
200
Molecules move from ______ to ________ concentration.
What is low to high?
200
A solution where the amount of water and solute are equal.
What is an isotonic solution?
200
The first beaker was in a ________ solution because the carrot/celery cells contained more salt than the water it was placed in.
What is hypotonic solution?
300
Used to compare results to the experimental group in an experiment. Load of laundry with no detergent. Plants with no fertilizer.
What is the control group?
300
Type of transport that moves molecules from high concentration to low concentration.
What is diffusion?
300
Waste molecules are packaged and moved OUT of the cell.
What is exocytosis?
300
A cell placed in this type of solution would shrivel up and lose water.
What is hypertonic solution?
300
We were observing this form of transport in the celery, carrots, and strawberries.
What is osmosis?
400
This is what we measure. It is always found on the y-axis. How tall the tomato plants grew.
What is the dependent variable.
400
Movement of water from a low solute concentration to a high solute concentration.
What is osmosis?
400
Examples are phagocytosis (cell eating) and pinocytosis (cell drinking). Cell membrane engulfs particles, forms a vesicle around them, and brings them inside the cell.
What is endocytosis?
400
A grape cell that was placed in a hyptonic solution would ____________?
What is absorb water.
400
This happened to our strawberry cells placed in a hypertonic solution.
What is shriveled/shrunk/got smaller?
500
This is the variable that we test in an experiment. Always found on the x-axis. Type of fertilizer.
What is the independent variable?
500
Helper proteins that act as "doorways" that let molecules that are too big into and out of the cell from high concentration to low concentration.
What is facilitated diffusion?
500
Use energy to move molecules through special channels in the cell membrane from low concentration to high concentration.
What are carrier proteins?
500
Water moves in and out of the cell to maintain balance.
What is hypertonic, hypotonic, isotonic.
500
This would happen to a raisin if it was placed in a beaker full of water.
