Body Systems
This body system is necessary to get glucose from food.
What is the digestive system?
This organelle houses the DNA of the cell
What is the nucleus?
The PRODUCTS of PHOTOSYNTHESIS are?
What are glucose and oxygen?
Muscle fatigue, your muscles feeling tired after exercise, is caused by the buildup of what molecule in your muscle cells?
What are waste products like CO2?
In diffusion, molecules move from _________ to ___________. This movement (does/does not) require energy input from the cell.
In diffusion, molecules move from HIGH CONCENTRATION to LOW CONCENTRATION. This movement does not require energy input from the cell.
What are the chemical messages called produced by the glands of your endocrine system?
What are hormones?
This organelle produces energy for the cell
The organelles that conduct photosynthesis in plants are ____________?
What are chloroplasts?
Why does the blood start pumping faster when we exercise?
To supply more oxygen to the cells to produce more ATP (energy).
In active transport, molecules move from _________ to ___________. This movement (does/does not) require energy from the cell.
In active transport, molecules move from LOW CONCENTRATION to HIGH CONCENTRATION. This movement does require energy from the cell.
This body system brings necessary molecules to every cell in the body.
What is the circulatory system?
This organelle synthesizes protein for the cell
These organelles conduct cellular respiration in BOTH animals and plants
What are mitochondria?
A group of similar cells working together is called __________?
What is a tissue?
Where molecules want to move depends on the ____________?
What is the concentration of the molecules?
Why do hormones only effect their target cells?
This organelle stores water and is only found in plants.
What is the large central vacuole?
What are the reactants and products of cellular respiration?
Reactants: Oxygen and Glucose
Products: ATP, Water, and Carbon Dioxide
In our diffusion lab, starch could not cross the cell membrane because it is too _________?
What is too big? Molecules cannot cross the cell membrane if they are too large!!!
Into the cell
What two systems are involved in taking in molecules from the environment to use for energy?
What are the digestive system and the respiratory system?
This organelle surrounds the cell and is semi-permeable.
What is the cell membrane?
Chloroplasts give off (produce) what two molecules?
Glucose and Oxygen - Chloroplasts are where photosynthesis happens, so it can be said the products of photosynthesis are what chloroplasts PRODUCE.
Why did exercise allow us to squeeze the clothespin longer?
Because the increased blood flow after exercise removed more carbon dioxide from our muscle cells in our hand, causing us to fatigue slower.
Inside the cell: 100 oxygen molecules, 30 carbon dioxide molecules, 20 protein molecules
Outside the cell: 30 oxygen molecules, 100 carbon dioxide molecules, 0 protein molecules
Which ways do oxygen and carbon dioxide diffuse?
