Plant Biology Quiz

The Venus fly trap is a carnivorous plant. It is found in subtropical wetlands of the United States. Their leaves consist of a terminal lobe hinged in the middle, forming a “trap”. The “hinged” portion of the “trap” is made up of specialized plant cells call “motor cells.” The inner portion of each lobe contains hair-like trichomes. The trap closes when two trichomes are touched in succession and trigger the motor cells to quickly change shape. This is an example of -

How do the structures labeled in the illustration of above interact during plant reproduction?

• Pollen from the Y structure transfers to the X structure to deliver sperm to the ovules

• Pollen from the X structure transfers to the Y structure to deliver sperm to the ovules

• Eggs from the Y structure transfer to the X structure to deliver ovules to the pollen.

• Eggs from the X structure transfer to the Y structure to deliver ovules to the pollen.

The structures of the roots and shoots systems work together to transport and provide materials essential for photosynthesis. Which statement correctly identifies how they work together?

• The xylem transports glucose to the roots for storage, and the phloem allows oxygen to enter the leaf.

• The xylem transports water from the roots up the plant, and the stomata allows carbon dioxide to enter the leaf.

• The phloem transports water for transpiration, and the stomata allows oxygen to enter the leaf.

• The stomata transports glucose from the roots, and the phloem allows carbon dioxide to enter the leaf.

A damaged stem would most likely affect what process within a plant?

• Movement of food and water between the roots and leaves.

• Excretion of oxygen by the mesophyll cells.

• Synthesis of auxins in meristematic cells.

• Absorption of water by the roots.

Photosynthesis occurs here, Have stomata for gas exchange, Absorbing Sunlight.

• leaves

• roots

• flower

• stem

Desert plants have structural adaptations and responses to external factors that help them survive the extremes of a hot and dry climate. One way desert plants respond to the extremes of a hot and dry climate is —

• having deep wide root systems

• having stomata on the tops of their leaves
