The liver is a collection of tissues that metabolize nutrients in the body. The liver is an example of -

• an organism.

• a cell.

• an organ.

• an organ system.

Neurons rapidly communicate information throughout the body. Neurons combine to form tissue in the organ known as the brain. Neurons are classified as -

• cells

• tissues.

• organs.

• organisms.

The roots of a plant help to anchor the plant to the soil, and are also used for food storage and water extraction. Roots are made up of tissues, such as xylem, phloem, and pith. In which level of organization would the roots of a plant most likely be classified?

• Cell

• Organ system

• Tissue

• Organ

The root and shoot systems in plants work together to form a more complex organization known as -

• a cell.

• an organism.

• a tissue.

• an organ.

In humans, the heart is an organ that pumps blood through blood vessels. The combination of the heart and blood vessels is classified as -

• a tissue.

• an organ.

• an organ system.

• an organism.

Which of the following lists includes cellular structures found in both plant and animal cells?

• Chloroplasts, cell wall, cell membrane, cytoplasm

• Vacuoles, cell membrane, nucleus, mitochondria

• Cell membrane, cytoplasm, nucleus, cell wall

• Chloroplasts, vacuoles, cell wall, cytoplasm

In an organism, the brain directs the body how to respond to stimuli from the environment. In a cell, this function is performed by the–

• cell membrane.

• chloroplasts.

• mitochondria.

• nucleus.
