cells .😒😒😒😒 Flashcards
What is cell theory?
Number One: all living things are made up of one or more cells
Number Two: the cell is the smallest unit of life
Number Three: all cells come from preexisting cells
List the macromolecules.
- Carbohydrates
- Proteins
- Lipids
- Nucleic acids
What is the difference between a plant and an animal cell?
A plant cell has a cell wall and chloroplasts.
What are the types of passive transport?
Diffusion-movement from an area of higher concentration to an area of lower concentration
Osmosis- diffusion of water molecules only through a membrane
Facilitated diffusion- when molecules pass through a cell membrane using transport proteins
What is the difference between passive and active transport?
Active transport uses the energy of a cell, and passive transport does not.
What is the difference between cellular respiration and photosynthesis?
. Cellular respiration is a series of chemical reactions that convert energy in food molecules into ATP. Cp: O2+glucos-> CO2, h20, ATP
Photosynthesis is a series of reactions that convert light energy, water, and CO2 into glucose and give off oxygen. P: CO2+H20+sun-> o2, glucose
carbohydrate
one or more sugar molecule
lipid
large macromolecule that does not dissolve in water
macromolecule
substance that forms by joining many small molecules
nucleic acid
macromolecule that forms when a long chain of nucleotides join together
protein
long chain of amino acid molecules
theory
explanation based on scientific knowledge resulting from several observations and experiments
endocytosis
process during which a cell takes in a substance by surrounding it with a cell membrane
exocytosis
process during which cell’s vesicles release their contents outsider the cell
cellular respiration
series of chemical reactions that convert energy in food molecules into ATP
