Unit 7 Test Review (Cell Structures, Inheritance, Survival)

Front

What is a behavioral adaptation?

Back

A behavioral adaptation is a change in behavior that helps an organism survive in its environment, such as hibernation in box turtles to conserve energy during winter.

Front

What organelle transforms radiant energy from the sun into glucose for plants?

Back

The chloroplast is the organelle responsible for photosynthesis, converting sunlight into chemical energy in the form of glucose.

Front

Which cellular structure synthesizes proteins in both plant and animal cells?

Back

Ribosomes are the cellular structures that synthesize proteins by translating messenger RNA.

Front

What is the extra protective layer found in plant cells called?

Back

The cell wall is the additional protective layer in plant cells, providing structure and support.

Front

What can mutations in DNA lead to in terms of traits?

Back

Mutations in DNA can lead to variations of traits, which may result in different characteristics among individuals.

Front

What is the function of mitochondria in cells?

Back

Mitochondria are known as the powerhouse of the cell, responsible for producing energy (ATP) through cellular respiration.

Front

Define structural adaptation.

Back

A structural adaptation is a physical feature of an organism that enhances its survival, such as the thick fur of polar bears for insulation.

Front

What is the role of the nucleus in a cell?

Back

The nucleus serves as the control center of the cell, housing the cell's genetic material (DNA) and coordinating activities like growth and reproduction.

Front

What is the function of the Golgi apparatus?

Back

The Golgi apparatus modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles.

Front

What is a physiological adaptation?

Back

A physiological adaptation is a functional change in an organism's internal processes that aids in survival, such as the ability of some animals to regulate their body temperature.
