Introduction To Cells Flashcards
He discovered cells by observing cork.
Hooke
Hooke named them cells because they reminded him of…
Monastery chambers/cells
He observed the first living cells.
Van Leeuwenhoek
This instrument is the reason cells were found.
Microscope
The first part of the cell theory states that all living things are composed of…
One or more cells
The second part of the cell theory states that cells are the basic unit of
Structure and function
The third part of the cell theory states that new cells come from…
Existing cells
This type of cell is simple and lacks a nucleus
Prokaryotic
This type of cell is complex and has a true nucleus.
Eukaryotic
This type of cell has no specialized organelles and is designed for survival.
Prokaryotic
This type of cell has many specialized organelles and is designed for a specific job.
Eukaryotic
This means “tiny organ”
Organelle
This structure protects the cell and regulates what can enter and exit the cell.
Plasma membrane
The membrane is thin, flexible, and composed of many pieces,like skin, providing
Protection
The is the “brain” of the cell…it contains DNA and controls cell functions.
The nucleus
This protects the DNA in the nucleus
Envelope (membrane)
This keeps everything in the nucleus in place
Nucleoplasm
This is a dense region where ribosomes are made
Nucleolus
These are found in the cytoplasm and will make proteins for the cell.
Free ribosomes
These are found attached to the ER and will make proteins that will eventually be shipped.
Bound ribosomes
This is a system of tubes filled with enzymes that will synthesize hormones, detox materials, and break down lipids.
Smooth ER
This is a system of sacs covered in ribosomes that will modify proteins
Rough ER
This is a stack of hollow, flattened sacs (or pancakes).
Golgi apparatus
This step by the Golgi is when the protein is received and double checked.
