Module 0 Flashcards
Who was Robert Hooke
the first person to observe cells. He called them “cellula” (Tree bark, little rooms)
Who was Matthias Schleiden
- All plant tissues are composed of cells
- Embryonic plant always arose from a single cell
Who was Theodor Schwann
- Similar observations in animal cells to Mathias Schleiden
- Structural similarities between plants and animals
Who are Hans Lippershey and Zacharias Janssen
arguably the inventors of the microscope
Who is Antonie Van Leeuwenhoek
worked with glass and improved the magnification of the microscope by 300x
He was the first to observe single celled protist from pond water
He observed bacteria from his mouth “father of microbiology”
Observed blood cells , banded paterns in muscle cells, giardia from p00 and sperm cells’
What is cell theory
All organisms consist of one or more cells
The cell is the basic unit of structure for all organisms
All cells arise only from pre-existing cells
What is the scientific method
Make observations
Develop a hypothesis
Make predictions based on your hypothesis
Observe more with controlled experiments to test your hypothesis
Interpret your results and see if they support your hypothesis
Robert Brown
Noticed that every plant cell contained a round structure (we now know it’s called nucleus)
What are general characteristics of a prokaryotic cell
No membrane bound nucleus
Naked DNA (fewer proteins), single , circular strand
Cell wall in addition to plasma membrane
What are characteristics of a eukaryotic cell
Membrane bound nucleus
More organelles
No flagella
What are the organelles found in a animal cell
What are the organelles found in a plant cell
What is the difference between a plant and animal cell
Plant cells have a cell wall
Plant cells have chloroplast
Plant cells have a big vacuoles
What are the four groups of Eukaryotes?
Explain the secretory pathway in a cell
