Cell Theory
To see cells you need this tool
A microscope
A Specialized structures within a cell that perform specific functions is called a ______
organelle
True or False: Some prokaryotes have a nucleus
False
True or False: ALL eukaryotes have a nucleus
TRUE
True or False: Prokaryotic and eukaryotic cells are both living
True
How do you calculate total magnification?
Objective lens x Eyepiece
Contains the cell's genetic material (DNA).
Nucleus
Name an example of a prokaryotic organism
Bacteria or Archaea
Name THREE examples of a eukaryote
any animal, plant, fungi...
Which type of cell is smaller and more ancient?
Prokaryote
An organism that is made up of ONE cell is called __________ while an organisms made up of MULTIPLE cells is called ________________.
Unicellular, Multicellular
Site of photosynthesis.
Chloroplasts
Why does antibiotics work against bacteria?
Bacteria has a cell wall (targeted by antibiotics)
Unlike prokaryotes, eukaryotic cells have these membrane-bound compartments that carry out specific functions
organelles
What is something that prokaryotes and plants have, but animal cells do not?
A cell wall
All cells come from pre-existing cells. What is the method to make new cells called?
Prokaryotes - Binary Fission ; Eukaryotes - Mitosis
Site of protein synthesis.
Ribosome
Where is the DNA found in prokaryotes?
Floating in the cytoplasm (in the nucleoid)
This organelle is responsible for generating energy in the form of ATP for the eukaryotic cell
The mitochondria
What are TWO things that plants and animal cells have but bacteria does not?
organelles (besides the ribosome), nucleus, larger/complex
List the THREE (3) parts of cell theory
1. All organisms are composed of 1 or more cells 2. The cell is the basic unit of life 3. All cells come from pre-existing cells
Network of membranes involved in protein and lipid synthesis and covered in ribosomes
Rough Endoplasmic Reticulum (RER):
This is the process by which prokaryotic cells reproduce
binary fission
This is the process by which eukaryotic cells reproduce
Mitosis
Name THREE structures that ALL cells have?
Cell membrane, cytoplasm, DNA, ribosomes
