History
What invention allowed us to discover cells?
What is a microscope?
Which cell is more complex? Why?
Eukaryotic; it is larger, has membrane bound organelles, and a nucleus.
What are the two functions of the nucleus?
Storing DNA and producing proteins
What is a tissue?
A group of similar cells working together to preform a specific task.
What system do the lungs belong to?
Respiratory
Who was the first to discover cells?
Who is Robert Hooke?
What 3 organelles do prokaryotic and eukaryotic cells have in common?
Ribosomes, cytoplasm, and membrane
What two organelles are only in plant cells?
Chloroplast and Cell Wall
What is an organ system and what would happen if one of its organs stopped working?
A group of organs with a related function.
The rest if the organ system would not be able to carry out its function.
What does the nervous system do?
Allows a response to stimuli.
What kind of cell did Robert Hooke observe?
What is a Dead Cork Tissue/Cell?
Which type of cell contains DNA?
Both prokaryotic and eukaryotic
What are the functions of the ER and Golgi Apparatus?
ER: Transports chemicals/proteins to and from the nucleus
GA: Modifies, packages, and sorts proteins
What are the four types of tissue?
Epithelial, Muscle, Connective, Nervous
What is the function of the Respiratory System?
Transports oxygen throughout the body.
How did cells get their name?
Hooke thought they looked like the monastery rooms called cells.
What organism has prokaryotic cell(s)?
Bacteria
What are the functions of the mitochondria and vacuoles?
Mito: produce energy for the cell
Vacuoles: stores food and water for the cell
What is an example of connect tissue?
Blood, bones, body fat, tendons, cartilage, ligaments.
What does the immune system do?
Protect the body from harmful/outside pathogens.
What are the 3 parts of the Cell Theory?
1. All living things are composed of one or more cells.
2. The cell is the basic unit of life.
3. New cells come from pre-existing cells.
What is the difference between a vacuole in a plant cells versus an animal cell?
Size! A plant cell has a larger vacuole to store more food and water.
Why do cells need cytoplasm?
Cytoplasm holds the organelles in place and provides structure for the cell.
What are the functions of the nervous and connective tissue?
N: process and transfer information (stimuli) over distances.
C: supports and connects tissue, bones, and muscles. Also supports organs and blood vessels.
What organ belongs to the integumentary system?
Skin, Nails, Hair, Nerves for skin
