Processes
What did we model using tofu and food coloring?
Surface area to volume ratio and diffusion
What type of cell has a nucleus?
Eukaryotic
What is the purpose of a flagella?
Movement of a cell
What is a capsule?
Protective layer around some bacteria
The lysosome is full of _____________ that break down materials.
Enzymes (a type of protein)
A special type of diffusion that only moves water rather than substances
Osmosis
What type of cell does not have a nucleus?
Prokaryotic
What is the purpose of a ribosome?
To make proteins
Name two types of cells that have a cell wall
Prokaryotes, Plant cells, Fungi cells
What "do the work" inside of our bodies?
Insulin is an example of one.
Proteins
Why are cells so small?
They need to keep a specific surface area to volume ratio so nutrients can diffuse.
What is a major difference between Fungi cells and plant cells?
Fungi cells don't have chloroplast
What is the purpose of a lysosome?
Breakdown / recycle waste products
What is the region in bacteria that has free floating DNA
the nucleoid
The semi permeable membrane that surrounds all cells cytoplasm and regulates chemical reactions.
Cell Membrane
The process of using glucose and O2 in the mitochondria to make ATP, CO2, and H2O
Cellular Respiration
What are three big differences between plant and animal cells?
Plant cells have: cell walls, chloroplast, and a large central vacuole
Animal cells have: a centriole
What is the purpose of the endoplasmic reticulum?
delivery system for proteins and membranes
What is a plasmid?
Circular DNA in bacteria used for sexual reproduction
This is a special part of the cytoskeleton that is used during cell division.
Centrioles
The process of using CO2 and H2O in the presence of sunlight to make glucose and O2
Photosyntheses
Name 4 structures that all cells have in common
Cell membrane, cytoplasm, ribosomes, DNA
The strong, porous outer layer of plant cells.
Cell wall
You're looking at some bacteria and it appears to be circular, what type of bacteria is it?
coccus
This provides cell structure and allows some cells to move, it is made of proteins called microtubules and microfilaments.
Cytoskeleton
