Potted Plant

Turgor pressure can help plants move. Internal water pressure can cause

• a wilted stem to return to an upright position.

• leaves to fall off a tree in autumn.

• the roots of a plant to grow downward.

• a seedling to be carried by the wind

Geotropism is a force that affects certain organisms. This force will result in which of the following?

• A flower to die due to lack of water

• The roots of a plant to grow downward

• Animals to seek shelter on high ground

• Fish to float to the surface when they die

Turgor pressure helps a seed in which of the following ways?

• Acquiring nutrients it needs from the soil

• Providing it energy without sunlight

• Conserving water until its roots grow

Geotropism explains which of the following phenomena?

• Water collects in rock crevices, freezes and expands, and shatters the rock.

• A seed is planted upside down, but the roots still grow in the direction of gravity.

• Two tectonic plates move toward each other, collide, and form a mountain.

• After a natural disaster, all animal life disappears from the affected area.

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

Water moves inside plants using xylem, a structure made up of a collection of cells that form the tube-like xylem. Xylem is classified as-

• a tissue

• an organ

• an organ sytem

• an organism

Roots grow downward in the soil in response to –

• gravity

• sunlight

• water

• wind
