Cell Basics and WILD CARDS
This cell type contains a cell wall
What is... a PLANT CELL
This organelle is the manager of the cell, it stores genetic material.
What is... the NUCLEUS
This part of a phospholipid loves to interact with water
What is... the PHOSPHATE HEAD
This type of transport moves AGAINST the concentration gradient using energy
What is... ACTIVE TRANSPORT
These terms, in order, describe a:
1. Cell that has a HIGHER concentration of solute than the environment
2. Cell that has a LOWER concentration of solute than the environment
3. Cell that has the SAME concentration of solute as the environment
What are...
1. HYPERTONIC
2. HYPOTONIC
3. ISOTONIC
Cells that do NOT contain a nucleus or any other membrane bound organelles.
What is... a PROKARYOTIC CELL
This organelle is the powerhouse of the cell
What is... the MITOCHONDRIA
This part of a phospholipid is NONPOLAR
What are... The LIPID TAILS
This type of transport includes facilitated diffusion and simple diffusion
What is... PASSIVE TRANSPORT
When red blood cells are placed in this type of solution, the cells might swell with water and could eventually burst!
What is... a HYPOTONIC solution
This type of cell has a "good" or "true" nucelus
This organelle is the outermost border around animal cells.
The part of the a phospholipid that can interact with oil better than water.
What are... THE LIPID TAILS
These types of transport both require protein channels
What are... FACILITATED DIFFUSION AND ACTIVE TRANSPORT
When plant cells are placed in this type of solution, the cytoplasm shrivels up and peels away from the cell wall!
What is... a HYPERTONIC SOLUTION
This is the variable that a scientist measures during an experiment.
What is... a DEPENDENT VARIABLE
This organelle help make lipids and also detoxifies the cell
What is... the SMOOTH ER
Our cells are filled with AND surrounded by water, this results in the membrane have phospholipids on the outside and the inside of the cell, both with the tails facing in and the heads facing out. The term that describes this double membrane structure is...
What is... a BILAYER
This type of transport involves small, nonpolar molecules
What is... SIMPLE DIFFUSION
A freshwater fish is placed into a salt water fish tank. The fish dies. Explain why.
The fish is HYPOTONIC compared to the fish tank (which is HYPERTONIC). The water leaves the fish to dilute the salt in the tank and the fish dehydrates and dies.
In an experiment, a scientist is looking at the food preference of isopods. The isopods were given carrots, potatoes, and cabbage. The number of isopods eating each food were counted after waiting 30 minutes. What is the independent variable?
What is... The food type! (Carrots, Potatoes, Cabbage)
This organelle contains special enzymes that break down things in the cell... kind of like a trash truck.
What is... the LYSOSOME
This 2 word term describes the fact that membranes allow some materials to pass through, but not all of them!
What is... SELECTIVELY PERMEABLE
This two word term describes the difference in the amount of "stuff" on each side of a membrane
What is... A CONCENTRATION GRADIENT
Why do plant cells not burst when placed into an HYPERTONIC SOLUTION?
Because the water is being pulled out of the cell, not into the cell. (In a hypertonic solution, there is not risk of bursting.)
Trick question: If the cell was in a HYPOTONIC solution, the cell wall prevents it from bursting.
