Scientists & History
This scientist first saw plant “cells” and named them such.
Robert Hooke
These cells have a nucleus.
Eukaryotes
This organelle is houses the cell's DNA.
Nucleus
This is the interior fluid within a cell
Cytosol
The rough ER contains these
Ribosomes
He discovered bacteria and protozoa, what he called, "animacules"
Anton van Leeuwenhoek
These cells lack membrane-enclosed organelles.
Prokaryotes
This is the irregular region where DNA is found in prokaryotes.
Nucleoid
This organelle is the "powerhouse" of the cell
Mitochondrion
The Golgi apparatus does this with proteins
Distributes
This scientist was the first to observe animal cells under a microscope
Theodor Schwann
Name the two main groups of prokaryotes.
Bacteria
Archaea
These are small loops of DNA found in prokaryotes.
Plasmid
This ER degrades hormones, drugs, and toxins
Smooth
This organelle degrades substances harmful to a cell
Peroxisome
Ignaz Semmelweis was the first to argue this
Washing hands prevents the spread of disease
Archaea are often found in these environments.
Extreme environments
This long appendage helps some prokaryotes move.
Flagellum
This small organelle is the site of protein biogenesis
Ribosome
Vacuoles are large sacs that contain this
Water
List the three main ideas of modern cell theory.
All organisms are made of cells
Cells are the basic organizational unit of life
All cells come from pre-existing cells
How does a nucleus differ from a nucleoid?
A nucleus has a membrane
This is the selective barrier that surrounds the cell
Cell membrane
This is the internal, supportive structure of the cell
Cytoskeleton
This is a small sac that degrades proteins, lipids, and carbs
Lysosome
