PROKARYOTES VS. EUKARYOTES
This structure acts as the cell's command center in eukaryotes, but is completely missing in prokaryotes.
What is the nucleus?
Who is Robert Hooke?
This English scientist looked at a thin slice of cork under a self-built microscope in 1665 and gave cells their name.
Mitochondria have their own DNA and are bounded by a double membrane; the folds of the inner membrane are known by this specific term
What are cristae?
You must always start viewing a new slide using this power objective.
What is low power?
Fluid portion of the cell outside the nucleus
What is Cytoplasm?
Unlike eukaryotic cells, prokaryotes pack their DNA into this irregularly shaped, membrane-less region.
What is the nucleoid?
The total number of core principles that make up the classic Cell Theory.
What is three?
This organelle is covered in ribosomes, giving it a bumpy appearance, and is heavily involved in protein folding and transport.
what is the rough endoplasmic reticulum (Rough ER)?
He built single-lens microscopes and was the first to observe living single-celled organisms in pond water (calling them "animalcules").
Who is Anton van Leeuwenhoek?
Property of biological membranes that allows some substances to pass across it while others cannot; also called semipermeable membrane.
What is Selectively permeable?
This cellular organelle, responsible for generating ATP, is present in eukaryotes but absent in prokaryotes.
What is the mitochondrion?
What is a cork (or plant cell wall)?
What Robert Hooke was actually looking at when he named "cells" were really the dead, rigid outer layers of this plant tissue.
This flat stack of membranes acts as the cell's "shipping and handling" department, sorting and packaging proteins for their final destinations.
What is the Golgi apparatus (or Golgi body)?
This small, thin piece of glass or plastic is placed at a 45° angle over a water drop to cover the specimen.
What is a cover slip?
Organelle in cells that modifies, sorts, and packages proteins and other materials from the endoplasmic reticulum for storage in the cell or release outside the cell.
What is Golgi apparatus?
While both cell types have this protein-building machinery, prokaryotes have a smaller 70S version compared to the eukaryotic 80S versio
What is the cell wall?
Who is Carl Nägeli?
This scientist discovered the plasma membrane (cell membrane).
Plant cells feature one massive version of this organelle to store water and maintain turgor pressure.
What are lysosomes?
This light source can either be a built-in electric bulb or a physical component that bounces light up through the stage.
What is a mirror (or illuminator/light source)?
What is a Vacuole?
These small, circular, extra-chromosomal DNA molecules are commonly found in prokaryotes and often carry antibiotic-resistance genes.
What are plasmids?
The approximate number of years that passed between Hooke's 1665 cork observation and the full formulation of the Cell Theory.
What is about 200 years?
These green organelles capture light energy from the sun to produce sugars through photosynthesis.
What are chloroplasts?
As the power of magnification increases, the size of this circular viewing area actually decreases.
What is the field of view?
Strong, supporting layer around the cell membrane in some cells.
What is a Cell wall
