The Living Cell Flashcards
What Are The Three Parts of The Cell Theory?
- All Living Things Are Made of Cells
- Cells are the basic unit of life
- All cells come from other cells
What are the two types of Cells?
Prokaryotes and Eukaryotes
Prokaryotes are single or multi-celled?
Single
Do Prokaryotes have Nucleuses?
No
Can Eukaryotes be single-celled?
Yes
What makes Eukaryotes different from Prokaryotes?
Eukaryotes have a nucleus
What did Lynn Margulis propose?
A concept called Endosymbiosis
What is Endosymbiosis?
It is a theory by Margulis that says that organelles within a cell were once capable of living alone by themselves
What is the job of the Nucleus?
It is the control center of the cell
What does the Nucleus consist of?
Chromatin (blocks that make up Chromosomes), and the Nucleolus
What is the barrier of the Nucleus called?
The Nuclear Envelope
What is the job of the Chromatin?
To make chromosomes; also contains DNA
What is the job of the Nucleolus?
It makes ribosome components
What is the job of the Nuclear Envelope?
It’s job is to encase the Nucleus
What is the job of the Cytoplasm?
It is a place where cell metabolism takes place
What are the components of the cytoskeleton?
The Microtubules, Microfilaments, and Intermediate Filaments
What is the job of the Microtubule?
It gives structure to the cell; forms roads for organelles to move along
What is the job of the Microfilaments?
Changes the cell shape; acts like contraction; helpful for moving the entire cell body
What is the job of the Intermediate Filament?
It is the spider-web of the cell; holds everything together
What is the job of a Vesicle?
To act as a short term storage sack
What is the job of the Mitochondria?
It enables cellular respiration; powerhouse of cell
What is the job of a Free Ribosome?
It helps make proteins for use inside the cell
What is the job of the Rough Endoplasmic Reticulum?
To produce proteins for use outside the cell
What is the job of the Smooth Endoplasmic Reticulum?
To make Lipids
