100 Points: What are the two basic types of cells?
Answer: Prokaryotic and eukaryotic cells.
100 Points: What three parts do all cells have in common?
Answer: Cell membrane, genetic material, and organelles.
100 Points: What is the main function of the mitochondria?
Answer: To produce energy (ATP) for the cell.
200 Points: Who was the first person to describe cells, and what did he observe?
Answer: Robert Hooke; he looked at cork.
200 Points: What is the second part of the cell theory?
Answer: The cell is the basic unit of all living things.
200 Points: Describe a prokaryotic cell.
Answer: A cell without a nucleus or membrane-bound organelles.
200 Points: Where is the genetic material found in eukaryotic cells?
Answer: In the nucleus.
200 Points: What does the Golgi complex do?
Answer: It packages and distributes proteins.
300 Points: Why are most cells too small to be seen by the naked eye?
Answer: Because they need a microscope to see their small size.
300 Points: What is the third part of the cell theory?
Answer: All cells come from existing cells.
300 Points: What is a eukaryotic cell?
Answer: A cell that has a nucleus and membrane-bound organelles.
300 Points: What structure surrounds and protects the cell?
Answer: The cell membrane.
300 Points: What role do lysosomes play in a cell?
Answer: They break down waste and damaged organelles.
400 Points: What is the meaning of the word "cells" in Latin?
Answer: Little rooms.
400 Points: Why is the cell theory important in biology?

Answer: Bacteria.
400 Points: What is the function of ribosomes?
Answer: They are the site of protein synthesis.
400 Points: Why don’t animal cells need chloroplasts?
Answer: Because they do not carry out photosynthesis.
500 Points: Describe how Anton van Leeuwenhoek contributed to cell discovery.
Answer: He studied pond organisms and discovered bacteria using his microscopes.
500 Points: Compare the cell theory to a basic principle in physics like Newton's First Law.
Answer: Both represent foundational truths in their respective fields.
500 Points: Give one example of a unicellular organism and a multicellular organism.
Answer: Unicellular: Bacteria; Multicellular: Humans.
500 Points: Compare the functions of smooth ER and rough ER.
Answer: Smooth ER makes lipids; rough ER has ribosomes that make proteins.
500 Points: Explain how the structure of the cell membrane relates to its function.
Answer: The cell membrane is selectively permeable, allowing certain materials in and out while protecting the cell.
