Characteristics of Living Things
Concentration & Gradients
Organization of Life
100
What is the function of the nucleus?
It is the control center of the cell and hands out orders to the rest of the cell parts
100
How does the cell membrane let things in and out of the cell?
It has pores (or holes)
100
All living things are made of what?
Cells
100
Extra Credit: What's the difference between active and passive transport?
Active transport uses energy
100
What is the smallest level of organization?
Cell
200
What is the function of the lysosome?
It is the garbage disposal of the cell; it breaks down waste
200
Why can some things enter the cell membrane while other things cannot?
They are too big to fit through the pores
200
Is the following a characteristic of living things? All living things have a pulse.
No!
200
Which way does water always move to even out a concentration gradient?
The opposite of ions
200
What is the level of organization immediately after cells? (What do you get when you group together cells?)
Tissue
300
What is the function of the vacuole?
It is the storage of the cell; if holds food and water until it is needed.
300
Which organelle packages proteins ready to be sent to the body?
Golgi Bodies
300
Is the following a characteristic of living things? All living things grow and develop.
Yes!
300
How will ions move when there is a concentration gradient?
From high to low concentration (or to even it out)
300
What is the largest level of organization?
Organism
400
Which organelles makes proteins?
Ribosome
400
What is the function of the rough ER?
It is covered in ribosomes and transports proteins to other locations.
400
Is the following a characteristic of living things? All living things breathe.
No!
400
Why did the pure (distilled) water egg get bigger?
Because water went into the egg to even out the concentration gradient.
400
What is the level of organization immediately after tissue? (What do you get when you group tissue together?)
Organ
500
What is the difference between the rough ER and the smooth ER?
The rough ER is covered in ribosomes.
500
What is the function of the smooth ER?
It creates and stores large molecules and ions
500
Why isn't fire alive?
It is not made of cells
500
Why did the salt water egg get smaller?
Because the water went out of the egg to even out the concentration gradient
500
What is the level of organization immediately following organs? (What do you get when you group organs together?)
Organ system
