Biology Flashcard

Front

What is the role of the skeletal system in the human body?

Back

The skeletal system provides structure, support, and protection for the body, similar to how wood frames a house.

Front

What is homeostasis?

Back

Homeostasis is the process by which organisms maintain a stable internal environment despite changes in external conditions.

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two identical daughter cells, each with the same number of chromosomes as the parent cell.

Front

What are the main components of a cell?

Back

The main components of a cell include the cell membrane, nucleus, and cytoplasm.

Front

What is the function of alveoli in the lungs?

Back

Alveoli are tiny air sacs in the lungs where gas exchange occurs; they allow oxygen to enter the blood and carbon dioxide to be expelled.

Front

What structures are common to both plant and animal cells?

Back

Common structures include the cell membrane, nucleus, and mitochondrion.

Front

What is the function of the circulatory system?

Back

The circulatory system transports nutrients, gases, hormones, and waste products throughout the body.

Front

How do organisms maintain homeostasis through behavior?

Back

Organisms can maintain homeostasis by changing their behavior, such as moving to a cooler area to regulate body temperature.

Front

What is the difference between plant and animal cells?

Back

Plant cells have a cell wall and chloroplasts, while animal cells do not.

Front

What is the purpose of the cell membrane?

Back

The cell membrane controls what enters and exits the cell, maintaining the internal environment.
