This organelle directs cell processes by providing DNA instructions. It is surrounded by its own membrane and is covered with pores.
What is the nucleus?
200
These structures are used in plants to absorb sunlight to make food
Chloroplasts
200
The property of the cell membrane that allows some materials to pass through but not others
what is selective permeability
300
Which part of the cell theory was discarded due to new evidence?
Spontaneous generation
300
What stages of the cell cycle make up interphase?
G1, S, G2
300
This organelle is a series of flattened membranes. Cell products such as proteins pass through these membranes and become packaged for delivery in or out of the cell.
What is the Golgi apparatus
300
This organelle digests worn out cell parts and also plays a role to defend the cell from infection.
What is a lysosome?
300
This occurs when water diffuses into a cell.
What is osmosis?
400
During which process do cells divide from pre-existing cells?
Mitosis
400
What are the 4 stages of mitosis?
Prophase, metaphase, anaphase, telophase
400
This organelle is a series of interconnected passageways. Proteins and lipids are synthesized (put together) here also. There are two varieties 'S' and 'R'.
What is the endoplasmic reticulum?
400
These are made by the nucleolus and their function is to follow DNA instructions to make proteins. They are free-floating or may be found attached to the ER.
What are ribosomes?
400
What would happen to your cells in a hypotonic environment?
They would burst
500
list each statement of the cell theory... list the 3 statements
1. All living things are made of cells. 2. Cells are the basic unit of life. 3. Cells only come from other cells.

In developing new cancer drugs, scientists are trying to target the part of mitosis when the chromosomes start to move to opposite sides of the cell before it divides. Which phase of mitosis should they target?
Anaphase
500
These 3 organelles are involved in the synthesis of enzymes (Reminder: enzymes are proteins)
What are the ribosomes, the Golgi body, and the endoplasmic reticulum
500
The three differences between plant and animal cells are:
1. Plant cells have cell walls. 2. Plant cells have chloroplasts 3. Plant cells have a vacuole
500
The sodium/potassium pump requires ATP to pump against the concentration gradient. This is an example of this type of transport.
