Cell Membrane
Prokaryotes vs Eukaryotes
Cell Organelles & Structures
Active vs Passive Transport
Osmosis
100
This structure is found in both plant and animal cells and controls what enters and leaves the cell.
What is the cell membrane?
100
The type of cell humans contain.
What is eukaryotic cells?
100
This rigid structure provides support and protection for plant cells only.
What is the cell wall?
100
This type of transport requires no energy and moves substances down their concentration gradient.
What is passive transport?
100
This is the movement of water across a selectively permeable membrane.
What is osmosis?
200
Which part of the phospholipid is nonpolar?
What is the hydrophobic tail?
200
An example of this would be a bacteria cell.
What is prokaryote?
200
This organelle produces energy for the cell. Muscle cells in the human body have a higher number of these since they need more energy.
What is the mitochondrion?
200
This type of transport requires energy to move substances against the concentration gradient.
What is active transport?
200
A solution with equal solute concentration inside and outside the cell is called this.
What is an isotonic solution?
300
These phospholipid parts are hydrophilic and face the watery environments inside and outside the cell.
What are phospholipid heads?
300
This is jelly-like substance that fills both eukaryotic and prokaryotic cells?
What is cytoplasm?
300
This structure allows plants to make their own food using sunlight.
What is the chloroplast?
300
This form of passive transport requires a carrier or channel protein.
What is facilitated diffusion?
300
Placing a plant cell in this solution causes it to lose water and wilt.
What is a hypertonic solution?
400
This membrane protein allows specific larger or charged molecules to pass through the membrane.
What is a channel protein (or carrier/transport protein)?
400
This organelle controls many cell activities and contains genetic material in Eukaryotic cells. I call this the call's brain.
What is the nucleus?
400
This large organelle stores water and helps maintain turgor pressure in plant cells. Animal cells have smaller versions of these to store water, water and nutrients.
What is the central vacuole?
400
This transport process removes materials from the cell using vesicles.
What is exocytosis?
400
In this solution, water moves into the cell, possibly causing it to swell or burst.
What is a hypotonic solution?
500
This term describes the membrane’s ability to allow some substances to pass while blocking others.
What is selective permeability?
500
These structures are found in prokaryotes and eukaryotes and assemble proteins and may be found free-floating or attached to the ER.
What are ribosomes?
500
This organelle modifies, sorts, and packages proteins for transport.
What is the Golgi apparatus?
500
This process allows large particles to enter the cell by engulfing them.
What is endocytosis?
500
Drinking seawater causes cells to lose water because seawater is this type of solution.
What is a hypertonic solution?
600
This model describes the cell membrane as flexible and made of many different parts.
What is the fluid mosaic model?
600
This type of organism would not be killed by a poison that blocks pores in the nuclear membrane because it lacks a nucleus.
What are bacteria?
600
This organelle contains enzymes that break down waste and old cell parts.
What is a lysosome?
600
The dispersal of food coloring in a beaker of water is an example of?
What is diffusion?
600
A cell is in an isotonic environment. Water molecules move in and out of the cell at equal rates, so the cell’s size stays the same.
What is dynamic equilibrium?
