Summary Introduction

Introduction:

Various organelles in the plant cells perform different functions, for example: stomatal opening allows the transfer of gas, tracheid’s which are the elongated cells helps in the transportation of nutrients, cuticle is a type of wax lining in plants that prevents desiccation.

Answer to Problem 1U

Correct answer:

The stomata opening for respiration, trachieds for transportation and cuticle prevents the transpiration in terrestrial areas. Therefore, the option d. is correct.

Explanation of Solution

Reason for the correct statement:

The respiration in plants includes the exchange of oxygen and carbon dioxide, is done by stomata opening. The movement of water and minerals is the function of vascular tissues which includes the tracheids. The cuticle is layer of wax on leaves that prevents the loss of water through plants. All of these are the function of plant structures.

Option d. is given as “All of the choices are matched correctly”.

As, “stomata-allows gas transfer, tracheids-allow the movement of water and minerals, cuticle-prevents desiccation, all are matched to its correct function”, it is the right answer.

Hence, the option d. is correct.

Reasons for the incorrect statements:

Option a. is given as “stomata-allow gas transfer”

The leaves have small openings which are responsible for their respiration. It is possible by the closing and opening of stomata. Other options are also correct, so it is a wrong answer.

Option b. is given as “tracheids-allow the movement of water and minerals”

The tracheids are the circular organelles present in the xylem vascular tissue responsible for the transportation of water and minerals. Other options are also correct, so it is a wrong answer.

Option c. is given as “cuticle-prevents desiccation”

The cuticle is the waxy layer on leaves that prevents the water vaporization in plants. Other options are also correct, so it is a wrong answer.

Hence, options a., b., and c. are incorrect.

Conclusion

The stomata, tracheids and cuticle all perform a specific function in the plants. So, all the options are correct.
