Which means of transport requires an input of energy?
Active Transport
What is contained within the cytoplasm that means "little organs?"
Organelles
Which part of the phospholipid is hydrophobic and what does that mean?
The two tails are hydrophobic and it means "water hating".
Who is credited with the invention of the microscope?
A. Antoni Van Leeuwenhoek
B. Robert Hooke
C. Robert Miller
D. Matthias Schleiden
A. Antoni Van Leeuwenhoek
What is the diffusion of water across a selectively permeable membrane called?
Osmosis
The cell membrane contains channels/doors that perform selective permeability as materials get transported from one side to another. What is the structure of those doors?
a. carbs
b. Lipid
c. Proteins
D. Bilipids
Proteins
Which structure modifies proteins making them specific using coded instructions that come from the nucleus?
Ribosome
Which of the following is a function of the cell membrane?
A. protect and cover the cell; regulate what goes in and out
B. Make lipids for energy to be used by the cell
C. Store lipids, water, salt, and carbs
A. protect and cover the cell; regulate what goes in and out
Who is credited with being the first person to observe and name them cells?
A. Antoni Van Leeuwenhoek
B. Robert Hooke
C. Rudolf Virchow
D. Matthias Schleidan
B. Robert Hooke
Please draw a hypotonic solution and indicate which direction the water is moving.
Hypo = Low
Water moving into the cell
Why would it matter for the cell membrane to be selectively permeable?
Only let some things through, don't want anything and everything getting in/out of your cell
Which organelle would you expect to find in plant cells but not animal cells?
A. Chloroplast
B. Ribosomes
C. Mitochondrion
D. Smooth ER
Chloroplast
Unlike the cell membrane, the cell wall is
A. found in all organisms
B. a strong, rigid structure
C. composed of a lipid bilayer
D. Selectively permeable
B. a strong, rigid structure
Which of the flooring is a function of the nucleus?
A. Stores sugars
B. Builds proteins
C. Stores DNA
D. Packages Proteins
Stores DNA
What type of solution is it when water is flowing equally into/out of the cell at roughly the same rate?
Isotonic
Please describe the process of diffusion including what type of molecules are able to do it.
Go from high to low con., no energy, small uncharged molecules.
Which organelle breaks down materials needed for the cell?
A. Rough ER
B. Lysosome
C. Golgi Apparatus
D. Mitochondrion
Lysosome
Which of the following is a function of the cytoskeleton?
A. surround the cell
B. help a cell keep its shape
C. Help make proteins
D. Contain DNA
help a cell keep its shape
What is the structure (shape) and function of microtubules and microfilaments?
Microfilaments : Thin wires that provide support for the cell
For a plant cell, what is its ideal type of bath solution to be placed in.
Hypotonic --> Turgor Pressure
Explain the difference between endocytosis and exocytosis and phagocytosis and pinocytosis.
Endo = in
Exo = out
Phago = solid
Pino = liquid
What does the Golgi apparatus do?
FEDEX; organizes, sorts, sends out molecules where they need to go.
True or false: Only some cells have a cell membrane, but all cells have a cell wall.
False
List the three statements of cell theory in no particular order.
Cells are the basic unit of structure and function for life
All things are made up of cells
New cells come from already existing cells
Define hypotonic, hypertonic, and isotonic. What happens to an animal and plant cell in a hypotonic environment?
Hypo = low
Iso = Equal
Hyper = High
Water flows into the cell causing it to swell and burst for animal. For plant, cell membrane pushes against the cell wall allowing it to strand.
