Early Discovery of the Cell
What is SEM?
Scanning electron microscope
What is type of cells is DNA found in?
All Cells
What is the cell membrane made of?
Phospholipid Bilayer
What does a Nucleolus have to do with making proteins?
The nucleolus makes the ribosomes that help assemble the proteins
What transport does and does not require energy?
Active (Endocytosis and Exocytosis) require energy while Passive (Diffusion and Osmosis) does not require energy
Who looked at slices of a cork?
Robert Hooke
What does not have a nucleus?
Prokaryotes
What is the structure of the cell membrane?
thin, flexible barrier that surrounds the cell
Where are the proteins assembled?
Ribosomes and Rough ER
Endcytosis brings things into the cells
What are the 3 requirements of the cell theory?
1. all living things are made up of cells
2. the basic units of structure & function in living things
3. new cells are made up of existing cells
What does have a cell wall?
Plant Cells
How can the cell membrane stop things from getting into the cell?
Because the cell membrane is Selectively Permeable
What does the Golgi Apparatus do?
The Golgi Apparatus packages and modifies the proteins, and tells them what to do and where to do it
What's the difference between Osmosis and Diffusion?
Osmosis only transports water into the cell, and Diffusion is the movement of molecules for an area of HIGH concentration to and area of LOW concentration
What is TEM?
Transmission Electron Microscope
This has a nucleus.
Eukaryotes
What are the "tails" in the cell membrane called?
Hydrophobic Tails
What is the order of the organelles in the protein synthesis?
Nucleolus, Ribosomes, Rough ER, Golgi Apparatus, Vesicle
What type of transports are their?
Passive and Active Transport
Who was the first person to observe living microoganisms?
Anton Van Leeuwenhoek
What does not have a cell wall?
Animal Cells
What are the "heads" of the cell membrane called?
Hydrophilic Heads
What are the 5 steps in protein synthesis?
The Nucleolus makes the Ribosomes, then the proteins are assembled on the Ribosomes, then some proteins finish their assembly on the Rough ER, then the proteins are carried to the Golgi Apparatus in the Vesicles, then the Vesicles ship the proteins to their final destination in or out of the cell
What are the 6 types of transport?
Diffusion, Facilitated Diffusion, Osmosis, Protein Pumps, Endocytosis, and Exocytosis
