Chapter 23, Problem 1STP

Summary Introduction

Introduction:

Along with the cell wall in a plant cell,many different cells have a specific function and form tissue. Three types of cells form the plant tissues. They function together to provide food production and storage; give flexibility, support, and strength to the plants. Parenchyma is the most flexible and thin cell found in the plants. Similarly, the transportation of nutrients, water, and other substances in plants is carried out by tissue-like xylem and phloem.

Answer to Problem 1STP

Correct answer:

The correct answer is option (C) phloem.

Explanation of Solution

Explanation/justification for the correct answer:

Option (C) phloem.The phloem tissue is made of living cells involved in the transportation of food and organic materials. They transport organic matter that forms during the photosynthesis process especially the sugar to different parts of the plant. So, the correct answer is option (C).

Explanation for incorrect answer:

Option (A) cambium. Cambium is a layer of tissue that provides undifferentiated cells partially for the growth of a plant. It is located in the portion between xylem and phloem. So, this is an incorrect option.

Option (B) parenchyma. Parenchyma is the most flexible and thin cell found in the plants. They are responsible for the structure of plants and have many other functions like food storage, gas exchange, photosynthesis, and protection. So, this is an incorrect answer.

Option (D) xylem.The xylem tissue is made of dead cells, involved in the transportation of water and other nutrients, and composed of fibers and tracheids. So, this is an incorrect answer.
