Concept explainers
Introduction: Plants are non-motile living beings that are capable of producing their own food by utilizing the sunlight, carbon dioxide, and water. They form the kingdom Plantae that includes all the plants such as trees, shrubs,

Answer to Problem 1TYU
Correct answer: Most of the plant body consists of the ground tissue system.
Hence, the correct answer is option (a).
Explanation of Solution
Reason for the correct answer:
The majority of the plant body consists of the ground tissue system because it is an essential portion of plants to supply mineral nutrients and water to the organisms. The ground tissue system includes parenchyma, collenchyma, and sclerenchyma which provide a variety of functions such as photosynthesis, storage, and support.
Option (a) is given as “ground”.
Most of the plant body includes ground tissue system as it is a necessary portion of plants to supply mineral nutrients and water to the organisms.
Hence, the correct answer is option (a).
Reasons for the incorrect answers:
Option (b) is given as “vascular”.
Vascular tissue system involves the vascular plants consist of two specialized tissues called the xylem and phloem those act as a conducting tube in plants for the transportation of water and sugar molecules throughout the plant. Most of the plant body does not consist of vascular tissue system.
Hence, option (b) is incorrect.
Option (c) is given as “periderm”.
Periderm is the type of dermal tissue found in the plant cell. In plants, there are only three tissue systems that include vascular tissue, ground tissue, and dermal tissue. Thus, periderm is not a tissue system.
Hence, option (c) is incorrect.
Option (d) is given as “dermal”.
The cell of dermal tissue that protects the soft tissue of plants also helps to control interactions with the plants and its surroundings and this is called dermal tissue system. Most of the plant body does not consist of dermal tissue system.
Hence, option (d) is incorrect.
Option (e) is given as “cortex”.
The outermost layer of root or stem of a plant is called cortex. In plants, there are only three tissue systems that include vascular tissue, ground tissue, and dermal tissue. Thus, cortex is not a tissue system.
Hence, option (e) is incorrect.
Hence, options (b), (c), (d), and (e) are incorrect.
Ground tissue system includes the tissues with only one cell type like the parenchyma, collenchyma, and sclerenchyma.
