Unit 2: Cell History & Organelles Flashcards
Type of cell that has a nucleus and other membrane-bound organelles
eukaryotic cells
Makes proteins for the membrane or for export to other cells
Rough ER
Two types of electron microscopes
Scanning
and
Transmission
Electron Microscopes
Type of cell that bacteria are classified as
prokaryotic cell
Organelles only found in plant cells
Chloroplasts
Central Vacuole
Cell Wall
Microscope that gives us an internal up-close view of a speciman
Transmission Electron Microscope
Component of cell walls
Cellulose
Contains the genetic material of the cell in eukaryotic cells
nucleus
During cellular respiration, this organelle breaks down large carbohydrate molecules into individual glucose molecules.
Lysosome
Helps to move around organelles inside the cell as well as products from the ER’s to the Golgi bodies.
Cytoskeleton
Concluded that all animals are made up of cells
Theodore Schwann
(Schwann=swan=animal)
Receives the products of the ER’s and ships them to the membrane for export.
Golgi apparatus
Came up with the word cell
Robert Hooke
Organisms that are only one cell in size are known as….
unicellular
Organism this is made up of more than one cell is called?
multicellular
Found inside of the nucleus. They synthesize (make) the ribosomes
nucleolus
Makes phospholipids (fats) for the cell membrane
smooth ER
Type of microscope that gives us an external 3D view of a specimen
Scanning electron microsope
Type of microscope that can view a living organism
Light microscope
Concluded that all cells come from preexisting cells
Rudolf Virchow
Helps make the cells mobile
cilia and flagella
Organelles only in animal cells
Lysosomes
Cilia and Flagella
Microscope that coats the speciman with a metal. Electrons bounce off the speciman and produce a surface image
Scanning electron microscope
Regulates the movement of food into the cell and waste out of the cell
Cell membrane
Concluded that all plants are made up of cells
Matthias Schleiden
Microscope that thinnly slices the speciman. Electrons are then forced through the speciman. The rate at which the electrons are collected on the other side is used to put together an image of the inside
Transmission electron microscope
Type of cell that lacks a nucleus
prokaryotic cell
First to look at protozoa (moving living organisms) in pond water
Anton Van Leewenhooke
Type of micoscope we use in the classroom
light microscope
