Cell Tissue Quiz
Questions: 16 · 10 minutes
1. During exercise, muscle cells need more oxygen. Which explanation best connects the relevant levels of biological organization?
Each muscle cell creates all the oxygen it needs from nothing
Muscle tissue changes state so oxygen can appear inside it
One organ system must be made from only one type of tissue
Respiratory and circulatory organ systems cooperate to supply oxygen to muscle tissue
2. The stomach contains epithelial, muscle, connective, and nervous tissues. What does this observation support?
An organ can contain multiple tissue types that contribute to its work
The stomach is a single cell with several nuclei
Different tissues cannot occur in the same body structure
Every tissue in an organ has exactly the same function
3. What is the smallest unit that can carry out the basic processes of life?
An organ
A tissue
A cell
An organ system
4. A tissue transports oxygen, nutrients, and wastes throughout the body in a liquid matrix. How is this tissue generally classified?
Epithelial tissue
Muscle tissue
Connective tissue
Nervous tissue
5. Solid dry ice changes directly into carbon dioxide gas. What is this change called?
Sublimation
Condensation
Melting
Freezing
6. An ice cube melts in a glass. Which statement correctly describes the change?
Water changes from liquid to gas and forms a new substance
Water changes from solid to liquid without becoming a new substance
The ice undergoes a chemical reaction with the glass
The water molecules become a different kind of molecule
7. Water droplets appear on the outside of a cold glass on a humid day. Which change of state produced them?
Evaporation of liquid from inside the glass
Condensation of water vapor from the surrounding air
Sublimation of ice through the glass
Freezing of oxygen in the air
8. Which statement best describes an organ?
It is one specialized cell performing every body function
It is a structure made of multiple tissues that performs particular tasks
It is a collection of identical organ systems
It is any nonliving material found inside the body
9. A sample contains long cells that shorten to create movement. Which type of tissue is it most likely to be?
Nervous tissue
Epithelial tissue
Connective tissue
Muscle tissue
10. Which description best defines a tissue?
A group of similar cells working toward a shared function
Several organ systems working together
One cell containing several organelles
A substance surrounding every organ
11. A student evaporates the water from a saltwater solution and finds salt crystals left behind. What does this best demonstrate?
Both substances disappeared during a chemical reaction
The salt was chemically converted into water vapor
The water changed state, while the dissolved salt could be recovered
The salt melted because evaporation always melts solids
12. Which cell structure regulates what enters and leaves the cell?
The nucleus
The cell membrane
The mitochondrion
The cytoplasm
13. Which example is a chemical change rather than only a physical change?
Crushing a metal can
Dissolving sugar in water
Freezing fruit juice into an ice pop
Iron forming rust after exposure to air and moisture
14. After a shallow scrape, new skin cells gradually replace damaged ones. Which process most directly makes the new cells?
Existing cells divide to produce additional cells
Skin tissue changes from a solid into a liquid
One tissue immediately transforms into a complete organ
Existing cells permanently enlarge without dividing
15. Under a microscope, a student sees rectangular cells with rigid outer boundaries and green structures. What is the best conclusion?
They are animal cells because all animal cells are rectangular
They are bacterial cells because bacteria contain green chloroplasts
They are plant cells with cell walls and chloroplasts
They are muscle cells specialized for contraction
16. Melted candle wax cools and becomes solid again. Which process occurred?
Evaporation
Condensation
Sublimation
Freezing or solidification
