What is the structure and function of the Plasma Membrane?
Structure: SEMIPERMEABLE membrane, made of a lipid bilayer and proteins
Function: controls what comes in and out of the cell, maintain homeostasis
100
What is the structure and function of chromatin?
Structure: "stringy" DNA, ramen noodles
Function: to be read by the cell, copied over, and used as a template to make RNA messengers
100
What is the process that mitochondria go through?
cellular respiration
100
A cell that does NOT contain a nucleus is called a ....
Prokaryotic cell

What is the structure and function of the Rough ER?
Structure: network of membranes/many folds, spotted with ribosomes
Function: transport system in the cell, especially for proteins
200
What is the structure and function of mitochondria?
Structure: pill- or bacteria-shaped with an inner folded membrane
Function: to convert sugar to cell energy (ATP) -- cellular respiration!!
200
This process TAKES IN sunlight, water, and carbon dioxide.
Photosynthesis
200
This is the word for a living thing that is made of only ONE cell
Unicellular organism
200
What are 3 differences between animal cells and plant cells?
Plant cells have chloroplast, plant cells have cell wall, plant cells perform photosynthesis plant cells have a central vacuole but animal cells have many small vacuoles, plant cells are square but animal cells are round
300
What is the structure and function of the nucleus?
Structure: surrounded by a nuclear membrane with pores, contains chromatin (DNA), and contains the nucleolus, also makes RNA
Function: controls the cell by sending instructions (RNA)
300
What is the structure and function of lysosomes?
Structure: small sacs full of ENZYMES (to digest)
Function: to digest or break down food/waste, to break down cell parts so the cell can re-use them
300
What do mitochondria TAKE IN to begin cellular respiration?
Sugar, and oxygen
300
This kind of cell is round, or irregularly shaped
Animal cell
300
What is the difference between Rough ER and Smooth ER?
Rough ER has ribosomes but Smooth ER does not
400
What is the structure and function of the cell wall?
Structure: rigid (tough) layer on outside of plant cells made of CELLULOSE (a tough plant fiber)
Function: provide structure and support for plant cells
400
What is the structure and function of ribosomes?
Structure: small and round, with a small and large subunit
Function: read RNA and make proteins
400
What are the products of photosynthesis?
SUGAR (glucose) and oxygen
400
A plant cell has a square shape because of THIS organelle
Cell wall
400
You are looking at a sample through a compound microscope using the 4x objective lens. What is the TOTAL magnification of your sample?
40X
4x (objective lens) x 10x (eyepiece) = 40X TOTAL
500
What is an important structure and function of chloroplasts?
Structure: contain chlorophyll
Function: convert sunlight to sugar (photosynthesis)
500
What is the structure and function of the vacuole?
Structure: no basic shape -- depends on the cell. can change shape as needed.
Function: stores water, waste, nutrients, and food for the cell
500
How do cells reproduce? What is this process called?
Mitosis
500
What kinds of cells are these? (need TWO words)
eukaryotic (has a nucleus) and animal cell (round shape)
500
What is it called when similar cells group up to perform a function together?
A tissue (--> organs --> organ systems --> organisms)
