Cell Organelle Structure
Describe the difference in the vacuole size between plant and animal cells.
Plant cells- this is the largest organelle
Animal cells- small
What is the function of the cytoplasm?
To cushion the organelles
What is the only molecule that can undergo osmosis?
Water
Collecting and Analyzing Data
What is the base unit of measurement for length?
Meter
Which organelle has a highly folded inner membrane?
The mitochondria
What is the function of the nucleolus?
To make ribosomes
Name the 3 types of passive transport we have discussed this year.
Diffusion
Osmosis
Facilitated Diffusion
If________________, then _______________. Fill in which variables should go where
IV, DV
Plant and animal cells are considered what type of cells?
Eukaryotic
An animal cell has this organelle to help with cell division? What does it send out during cell division?
Centriole and Spindle Fiber
Which organelle is responsible for turgor pressure?
The vacuole
What is the property of cell membranes which aids to the function of this organelle?
Semi-permeable
Selectively permeable
What type of graph compares categories?
Bar Graph
Name ALL of the parts of the nucleus?
Nuclear membrane
Nucleoplasm
Nucleolus
DNA or Chromatin(unwound DNA)
What is the outer most covering of a plant cell and what is it made of?
What is the function of chlorophyll AND chloroplasts?
Chlorophyll: Captures sunlight
Chloroplasts: Photosynthesis
The solute would want to move OUT of the cell and into the solution
Difference between control and constants?
Control is part of the IV and is used for comparison.
Constants are variables that must stay the same so that an experiment is valid
What are the 3 parts of the cell theory and who were the 3 scientists that contributed to this theory?
1. The cell is the basic unit of structure and function.
2. All living things are composed of 1 or more cell.
3. All cells come from pre-existing cells.
Virchow, Schleiden, and Schwann
See pictures for an answer.
MUST include: Polar, non-polar, hydrophobic, and hydrophilic, and phospholipid bilayer
What is the difference in the function of the Smooth ER and Rough ER?
The SER is responsible for making lipids and some hormones and controls the release of Calcium in muscle cells; while the RER is responsible for moving proteins throughout the cell.
What are the main differences between active transport and facilitate diffusion?
FD: High-->Low, uses a protein channel, DOES NOT use energy
AT: Low-->High, uses a protein carrier, uses ATP energy
Marcie is trying a new cookie recipe. She wants to see if the type of sugar she uses will make the cookies rise more. She makes three batches of cookies one bath with brown sugar, one with normal white sugar, and one with sugar substitute. The other ingredients were kept the same. Marcie baked each batch of the cookies for 12 minutes in a 350 degree oven and measured the height of the cookie as soon as they were taken out of the oven. What is the IV, DV, Control, and Constants?
DV: Height of cookie
Control: Normal sugar
Constants: will vary
What is the special Smooth ER called in muscle cells?
Sarcoplasmic Reticulum
