Cell Discovery & Theory
Name one of the three Cell theory principles
All living organisms are composed of one or more cells
Cells are the basic unit of structure and organization in living things
Cells only arise from previously existing cells that pass on genetic material
Main function of the Plasma Membrane
What is Homestasis
Diffusion of water across a selectively permeable membrane
What is Osmosis
_____Contains DNA
What is Nucleus
Powerhouse of the cell
What is Mitochondria
Types of Microscopes
What is Compound Light & Electron
______ Controls what enters and exits the cell
What is Selective Permeability
Net movement of particles from High to Low
What is Diffusion
____ function is Protein Synthesis
What is Ribosomes
____ Contains no nucleus or membrane-bound organelles
What is Prokaryotic
Difference between Prokaryotic and Eukaryotic
Prokaryotic(No nucleus, no membrane-bound organelles, smaller and less complex, and also most bacteria)
Eukaryotic(Contains Nucleus, specialized organelles present, larger, and more complex)
Membrane Components
Cholesterol, Glycoproteins & Glycolipids, and Transport Proteins(Carrier & Channel)
Uses channel and carrier proteins and moves ions and small molecules across the membrane
What is Facilitated Diffusion
Types of projections for cell movement
What is Cilia and Flagella
Main difference between Diffusion and Osmosis
Diffusion isn't water-based; however, Osmosis is.
This Dutch scientist was the first to observe living single-celled organisms, which he called “animalcules,” using his handcrafted microscopes.
Who is Antonie van Leeuwenhoek?
These parts of phospholipids are attracted to water and face outward toward the watery environments inside and outside the cell.
What are hydrophilic heads?
the process by which a cell surrounds an object in the
outside environment in a portion of the plasma membrane
What is Endocytosis?
capture light and convert it into chemical energy in a process called photosynthesis
What is Chloroplast?
This organelle contains digestive enzymes that break down waste materials.
What is a Lysosome?
____ discoverd what organism were made of
What is Robert Hooke
A type of protein connects with carbohydrates to make glycoproteins. Often found attached to the outside of the plasma membrane
What are peripheral proteins?
Na+/K+ (Sodium/Potassium Pump
Small disks called ________ are found in chloroplasts. ________ contain the green pigment chlorophyll
What is the Thylakoids
_____ Contains the green pigment chlorophyll
What is Thylakoids
