Looking at a cell under a microscope, you note that it is a prokaryote. How do you know?
What is lacks a nucleus
200
Which organelle breaks down organelles that are no longer useful?
What is lysosome
200
The diffusion of water across a selectively permeable membrane is called
What is osmosis
200
Give an example of an organ
What is heart
200
Which structures are responsible for cell movement?
What is microtubules and microfilaments
300
Which type of microscope can produce a 3D image of a cell's surface?
What is scanning electron microscope
300
Which structure makes proteins using coded instructions that come from the nucleus
What is ribosome

An animal cell that is surrounded by fresh water will burst because the osmotic pressure causes water to
What is move into the cell

A group of similar cells that perform a particular function is called
What is tissue
300
What are 2 functions of the nucleus?
What is control center of the cell and contains cell's DNA
400
The cell theory does not apply to: a. bacteria b. plants and animals c. multicellular organisms d. rock and soil
What is D
400
Which organelle converts the chemical energy stored in food into compounds that are more convenient for the cell to use?
What is mitochondria
400
The cell membrane contains channels and pumps that help move materials from one side to another. What are these channels and pumps made of?
What are proteins
400
What do cells use to communicate
What is receptors

List the 4 levels of organization in a multicellular organism in order from simplest to most complex
What is cell, tissue, organ, organ system
500
What are the three principles of cell theory?
What is 1. Cells are the basic unit of life 2. All living things are made of cells 3. All cells are produced from existing cells
500
Unlike the cell membrane, the cell wall is
What is a rigid structure
500
How are endocytosis and exocytosis similar? How are they different?
Both are forms of active transport of large molecules carried out by movements of the cell membrane. Endocytosis involves taking material into the cell, whereas exocytosis involves moving material out of the cell.

Distinguish between microfilaments and microtubules
What is microtubules are hollow tubes of protein that help maintain the shape of the cell. Microtubules also make up cilia and flagella, which function in cell movement. Microfilaments are long, thin fibers that are narrower than microtubules. Microfilaments function in the movement and support the cell
