Summary Introduction

Introduction:

Plant tissue is defined as a group of cells that carry out a specific function. It is a functional unit of the plant that connects all the organs (stems, leaves, and roots) of the plant with one another. The three basic types of the plant tissues are ground tissue that includes parenchyma, collenchyma, and sclerenchyma cells, vascular tissue that includes tracheids, vessel elements, sieve tubes, and companion cells, and dermal tissue that includes epidermal cells, trichomes and stomata.

Answer to Problem 1U

Correct answer:

Sclerenchyma cells are the thick-walled cells that lack the living protoplast at maturity. Therefore, option d. is correct.

Explanation of Solution

Reason for the correct statement:

The sclerenchyma cells are tough cells with rigid cell walls. They lack the living protoplast at maturity. They are rigid and non-living cells that provide strength to the plant.

Option d. is given as “Sclerenchyma”.

As “the sclerenchyma does not have a living protoplast at the time of maturity,” it is the right answer.

Hence, option d. is correct.

Reasons for the incorrect statements:

Option a. is given as “Parenchyma”.

Parenchyma tissues contain a living protoplast at maturity. Therefore, it is a wrong answer.

Option b. is given as “Companion”.

The protoplast is present in the companion cells at the time of maturity. Therefore, it is a wrong answer.

Option c. is given as “Collenchyma”.

Collenchyma tissues also have live protoplast at maturity. Therefore, it is a wrong answer.

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

Conclusion

Conclusion:

The plant cells that lack living protoplasts (all the components of the plant cell excluding the cell wall) at maturity are sclerenchyma.

Preoperative Diagnosis: Torn medial meniscus, left knee Postoperative Diagnosis: Combination horizontal cleavage tear/flap tear, posterior horn, medial meniscus, left knee. Operation: Arthroscopic subtotal medial meniscectomy, left knee Anesthetic: General endotracheal Description of Procedure: The patient was placed on the operating table in the supine position and general endotracheal anesthesia was administered. After an adequate level of anesthesia was achieved, the patient's left lower extremity was prepped with Betadine scrubbing solution, then draped in a sterile manner. Several sites were then infiltrated with 1% Xylocaine solution with Epinephrine to help control bleeding from stab wounds to be made at these sites. These stab wounds were made anterolaterally at the level of the superior pole of the patella for insertion of an irrigation catheter into the suprapatellar pouch area, anterolaterally at the level of the joint line for insertion of the scope and anteromedially at…
