Ans. Where is apical meristem found? 69. Parenchyma tissue is of further two types – Aerenchyma and Chlorenchyma. Aquatic plants have the air cavities in parenchyma. chlorenchyma. Correct! Question 9. Class 9 Science Chapter 6 Extra Questions Answers are important for the preparation of school tests as well as final exams. Parenchyma possesses intercellular air spaces and is named as Aerenchyma. When exposed to light, parenchyma cells may develop chloroplasts and are known as Chlorenchyma. Gas transport in the pathway may be simple diffusion or may be due to pressure flow (see Raven, 1996 and Jackson & Armstrong, 1999 for reviews). Page No. Question 4.
