To study for the test
What are cells?
The smallest and most basic unit of life.
Cells are like…
Specialized factories, full of machinery designed to accomplish the business of life.
Cells make up (1) from (2).
- Every living thing
- Blue whales to archaebacteria that live in volcanoes
Cells make up your…
Organs and tissues.
Cells do important jobs like…
Making bones, pumping blood, and digesting food.
Name 3 structures in a eukaryotic nucleus.
Nucleus, nucleolus, and chromatin.
Do prokaryotic cells contain a nucleus?
No.
Eukaryotic cells are found in…
Eukaryotes.
Some examples of eukaryotes are…
Animals, plants, protists, and fungi.
Eukaryotic cells differ depending on…
The type of organism.
Cells contain tiny structures called (1) that (2).
- Organelles
- Perform specific functions within the cell.
What is the circulatory system?
A network of organs and vessels that transport blood throughout the body.
What is the respiratory system?
A network of organs and tissues that enable the body to take in oxygen and expel carbon dioxide.
What is the digestive system?
A network of organs that break down food and liquids so the body can use them for energy, growth, and tissue repair.
What is the system of a cell?
A group of cells forming a collective entity.
What is the function of the nucleus?
The nucleus directs all cell activity and controls its size and reproduction.
What is the function of the nucleolus?
The nucleolus makes the ribosomes and writes the directions for how they should function.
What is the function of the cell membrane?
The cell membrane regulates what goes in and out of the cell.
What is the function of the mitochondria?
The mitochondria produces the energy needed for the cell’s functions.
What is the function of the golgi body?
The golgi body assembles and packages proteins for distribution.
What is the function of the vesicles?
Vesicles transport materials throughout the cell and go through the membrane to move materials out the cell.
What is the functions of the endoplasmic reticulum?
The endoplasmic reticulum transports proteins and other materials to other organelles in the cell.
Which type of endoplasmic reticulum contains the ribosomes?
The rough endoplasmic reticulum.
The ribosomes carry out the…
Proteins of the cell, which carry out a cell’s functions.
What are the functions of the vacuoles?
The vacuoles store food and water for the cell.
Which type of cells have larger vacuoles; Plant or Animal cells?
Plants.
What are the functions of the lysosomes?
Lysosomes break down worn-out cell parts and digest the cell waste.
What is the function of the cell wall?
The cell wall protects the cell and gives it structural support.
What are chloroplasts?
Chloroplasts are the protein-makers in the plant cells that convert light energy into chemical energy in the process of photosynthesis.
The organelle that looks like a bunch of firewood is called the…
Centriole.
What is the function of the centriole?
The centriole organizes microtubules that serve as the cell’s skeletal system.
The internal environment of the cell that contains a jelly-like substance is called…
Cytoplasm.
What is the function of the cytoplasm?
The cytoplasm holds all of the organelles inside of the cell.
