MISC 1
What are cells?
The basic unit of structure and function in living things.
What are the tiny structures that make up the cell?
Organelle.
What is a group of similar cells working together to perform a specific function?
Tissue.
What is an enzyme?
A type of protein that speeds up a chemical reaction in a living thing.
What is the longest part of the cell cycle?
Interphase.
What is the cell theory?
A widely accepted explanation of the relationship between cells and living things.
Which cell structure controls the functions of the cell?
Nucleus.
What is known as the powerhouse of the cell?
Mitochondria.
What is the fraction of water the human body is made up of?
About 2/3.
What takes place during cytokinesis?
During cytokinesis, the cell splits into two daughter cells each identical to the parent cell.
What was used to discover cells?
A microscope.
What is the difference between a plant cell and an animal cell? (use the structure)
Plant cells have a cell wall and a cell membrane while animal cells only have a cell membrane.
What is a compound?
A substance made of two or more elements chemically combined in a specific ratio, or proportion.
What are nuclei acids?
A very large organic molecule made of carbon, oxygen, hydrogen, nitrogen, and phosphorus, that contains the instructions cells need to carry out all the functions of life.
What are the stages of mitosis in order?
Prophase, Metaphase, Anaphase, and Telophase
(P, M, A, T)
Who discovered all cells were alive?
Aton van Leeuwenhoek.
What structure is known as the cells warehouse?
The cytoplasm.
What are the important organic compounds?
Lipids, proteins, carbohydrates, and nucleic acids.
What are the functions of cell division?
Cell division allows organisms to grow, repair damaged structures, and reproduce.
What takes place during interphase?
During interphase, the cell grows, copies its DNA, and prepares to divide into two cells.
What three things does the cell theory state?
All living things are composed of cells. Cells are the basic unit of structure and function in living things. All cells are produced from other cells.
How are multicellular organisms organized? (what is the sequence)
Tissues, organs, and organ systems.
What do cell membranes mostly consist of?
Lipid.
What are the three stages of cell division?
Interphase, Mitosis, and Cytokinesis.
During which phase of mitosis does the nucleus leave?
During prophase, the nucleus leaves.
