What is the function of xylem and phloem in plants?

Back

Xylem and phloem are vascular tissues in plants that transport water, nutrients, and food throughout the plant.

Front

What organ system in humans is similar to the function of xylem and phloem in plants?

Back

The cardiovascular system is similar as it transports blood, nutrients, and oxygen throughout the body.

Front

What is homeostasis?

Back

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

Front

Give an example of behavior that helps an organism maintain homeostasis.

Back

A snake moving from a sunny area to a shady area to cool down is an example of behavior that helps maintain homeostasis.

Front

What part of a plant cell produces sugar in the presence of sunlight?

Back

The chloroplast is the part of a plant cell that produces sugar through photosynthesis.

Front

What role does the skeletal system play in the human body?

Back

The skeletal system provides structure, support, and protection for the body's organs, similar to the frame of a house.

Front

What is the function of the circulatory system?

Back

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

Front

What is the role of the nervous system?

Back

The nervous system controls and coordinates body activities by transmitting signals between different parts of the body.

Front

What is the function of mitochondria in cells?

Back

Mitochondria are known as the powerhouse of the cell, as they produce energy (ATP) through cellular respiration.

Front

What is the significance of chlorophyll in plants?

Back

Chlorophyll is a pigment in chloroplasts that absorbs sunlight, allowing plants to perform photosynthesis.
