Question

Plants carry out gas exchange through _______.

• A. Vascular system
• B. Lenticels
• C. Stomata
• D. Mesophyll cells

Answer 1

Answer: (B), (C)

Stomata

Lenticels are raised pores found on the stem of a woody plant that allow gas exchange between the atmosphere and the internal tissues. Stomata are also pores that carry out similar function found on the underside of leaves and plants carry out gas exchange through these structures.
Vascular system that involves xylem and phloem help in the transport of water, mineral nutrients, and simple organic molecules from one part of the plant to another.
Mesophyll cells are found in leaves and are specialized for photosynthesis. These cells contain many chloroplasts, the organelles that perform photosynthesis.
