Flashcards in Introduction To Cells Deck (39):
Hooke named them cells because they reminded him of...
He discovered cells by observing cork.
He observed the first living cells.
This instrument is the reason cells were found.
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...
This type of cell is simple and lacks a nucleus
This type of cell is complex and has a true nucleus.
This type of cell has no specialized organelles and is designed for survival.
This type of cell has many specialized organelles and is designed for a specific job.
This means "tiny organ"
This structure protects the cell and regulates what can enter and exit the cell.
The membrane is thin, flexible, and composed of many pieces,like skin, providing
The is the "brain" of the cell...it contains DNA and controls cell functions.
This protects the DNA in the nucleus
This keeps everything in the nucleus in place
This is a dense region where ribosomes are made
These are found in the cytoplasm and will make proteins for the cell.
These are found attached to the ER and will make proteins that will eventually be shipped.
This is a system of tubes filled with enzymes that will synthesize hormones, detox materials, and break down lipids.
This is a system of sacs covered in ribosomes that will modify proteins
This is a stack of hollow, flattened sacs (or pancakes).
This step by the Golgi is when the protein is received and double checked.
This is when the Golgi wraps the protein in membrane and adds a carbohydrate "address" label.
This is when the Golgi transports the protein to the cell membrane
Any material wrapped in membrane to move from one place to another is called a
These are membrane enclosed catabolic enzymes that, along with a pH of 5, will digest and destroy broken down organelles and foreign material.
These are membrane enclosed enzymes that will neutralize substance such as alcohol and poison into hydrogen peroxide, and then in water.
This structure of the cytoskeleton is mostly responsible for movement.
Two proteins twisted together are responsible for maintenance of shape and placement of organelles.
These cables of twisted protein anchor down organelles and help keep shape.
These are tubes are hair-like and tail-like structures for cells.
Cilia and flagella
This is a tough layer of cellulose that provides plant cells with an extra layer of protection.
These are openings in the cell wall that allow water and nutrients to pass through.
This is an expandable storage sac that will hold everything from water, food, enzymes to waste and organic compounds.
These are membranous sacs filled with pigments that will conduct photosynthesis.
These are membranous sacs filled with pigments that will give color to flowers and fruit.
