Function of the cell membrane
Protective barrier, allows some substances in and keeps others out
200
Both osmosis and diffusion go from ______ to ______ concentration
high to low
200
What are the products of photosynthesis?
Glucose and Oxygen
200
What process in all living organisms breaks the bonds in glucose and releases CO2 into the atmosphere?
Cellular Respiration
300
The responding variable, the "effect" of a change in an experiment that you measure
The dependent variable
300
The function of the chloroplast
The site of photosynthesis, contains chlorophyll that gives the plant its green color
300
How is osmosis different from diffusion?
Osmosis is the movement of WATER molecules through a selectively permeable MEMBRANE
300
What part of the plant cell is the site of photosynthesis?
The chloroplast
300
How can animals, bacteria, fungi and protists get CARBON into their bodies to build cells and use for energy?
Eating plants and animals that are made of carbon compounds (consumption)
400
A question with a cause- effect relationship that can be answered through doing an experiment
A testable question, an investigation
400
The function of the mitochondria
The site of cellular respiration, breaks down sugar to make energy
400
Imagine a cell that contains 80% water, surrounded by a solution that contains 50% water. In which direction will the water flow? (in or out of the cell)
The water will flow OUT of the cell (Going from high to low concentration of water)
400
What part of the plant contains these food-making cells?
the leaves
400
How can dead plants and animals release carbon dioxide back into the atmosphere?
Decomposers break them down and release the carbon back into the air in the form of CO2
500
What is the independent variable in the following: Does heart rate increase if you increase the amount of caffeine a person drinks?
Amount of caffeine
500
What cell parts do plant cells have that animal cells do not have?
Cell wall, chloroplast and larger vacuole
500
Red blood cells contain a higher concentration of dissolved material than pure water. What will happen to red blood cells if they are placed in pure water? A. Water molecules will leave the cell, causing it to shrink B. Water molecules will enter the cell, causing it to expand C. Water molecules will be blocked by the cell membrane D. Water will pass back and forth, the cell will remain the same size
B. Water will flow INTO the red blood cell, causing it to expand
