Plants, Viruses & Systems Review

Roots of different plants can be connected by a network of underground fungal extensions called hyphae. These fungi contribute minerals to the roots and carbohydrates to the fungi. Which statement about the transportation of these substances within the plant is true?

• The minerals are transported from the phloem to the xylem in the shoot system.

• The carbohydrates are transported from the shoot system to the fungi by the xylem.

• The minerals are transported from the xylem by the roots.

• The carbohydrates are transported to the fungi through the phloem.

The body sometimes needs to send messages long distances by releasing hormones into the bloodstream. The hormones are then carried to the target location. Which body systems are involved in this interaction?

The (a)   system releases hormones into the bloodstream, and the ​ (b)   system carries them to the target location.

• endocrine
• circulatory
• respiratory
• immune
• nervous

What two systems would work most closely together to help a person fight an infection?

• Integumentary and Circulatory

• Immune and Digestive

• Circulatory and Respiratory

• Immune and Circulatory

Positive thigmotropism is a response in plants in which they move and grow toward an object the plant comes into physical contact with, usually curling around the object. This response of the shoot system benefits the plant by allowing the plant to —

• take in more carbon dioxide to convert into glucose

• reach more sunlight for photosynthesis

• absorb more water to transport to the leaves

• produce more pollen for pollinators

Water, sugar, and other important nutrients need to be transported from one part of a plant to another. Which statement correctly describes the interaction of the root transport?

• The leaves take in water and sugar, which are then transported to the rest of the plant through vascular tissues.

• The roots take in water and sugar, which are then transported to the rest of the plant through vascular tissues.

• The leaves take in water and the roots produce sugar that are transported to the rest of the plant through vascular tissues.

• The roots take in water and the leaves produce sugar that are transported to the rest of the plant through vascular tissues.

Both the respiratory system and the digestive system involve the uptake of necessary molecules from an animal's surroundings. Alveoli are tiny sacs that aid in the exchange of oxygen in the lungs. Intestinal villi are tiny projections along the lining of the intestines used to take in nutrients from food passing through. Which system must interact with the respiratory and digestive systems to transport gases and nutrients throughout the body?

• Endocrine

• Integumentary

• Immune

• Circulatory
