One of the characteristics of lenticels in woody plants is that they:
Correct answer: C. Are permanent pores that always remain open
- A. Have cells containing chloroplast
- B. Are located in the stem epidermis
- C. Are permanent pores that always remain open
- D. Are openings in the stem of shrubs that are regulated
Explanation
Unlike stomata, which open and close to regulate gas exchange, lenticels are permanent openings in the bark of woody plants.So option C is correct.

About Plant Nutrition and Transport
Plants require macronutrients and micronutrients for growth, and mineral deficiencies produce recognizable symptoms. Transport involves water and minerals through xylem by transpiration pull, cohesion and adhesion, while phloem translocates sugars from sources to sinks. Root pressure and transpiration are distinct mechanisms.
