Which of the following best describes the position of a tissue in the levels of organization of the human body?
Tissues are the most fundamental level of organization.
Tissues are between cells and organs in the levels of organization.
Tissues are the most complex level of organization.
Tissues are between organs and systems in the levels of organization.
Introduction:
Cell is described as the most basic and fundamental unit of life. It is the functional and structural unit. Cells organize themselves into tissues. Tissues are considered to be living fabrics. A particular tissue consists of cells, that are similar to each other in terms of functions.
Answer to Problem 1CYR
Correct answer:
Tissues are considered to be between cells and organs when comparing them according to levels of organization.
Explanation of Solution
Explanation for the correct answer:
Option (b) states that tissues come between cells and organs in the hierarchy of organizational levels. Structurally and functionally similar cells are grouped together, forming tissues. These tissues further group together, forming an organ. An organ carries out a specific function in the body. Hence, option (b) is correct.
Explanation for the incorrect answers:
Option (a) states that tissues are the most fundamental unit in the level of organization. This is false because the cells are the structural, functional, and fundamental units. They are a complete organizational structure performing different functions at a miniature level. So, it is an incorrect option.
Option (c) states that tissues are the most complex ones. This is false as organ systems are the most complex. Different organs form an organ system, performing a specific process in the body. For example, stomach, pancreas, liver, and others come under the digestive system. So, it is an incorrect option.
Option (d) states that tissues between the organs and systems. This is false because tissues are lie between cells and organs. Cells form tissues, tissues form organs, and organs form organ systems. So, it is an incorrect option.
Hence, options (a), (c), and (d) are incorrect.
Therefore, tissues are placed between cells and organs in the levels of organization.
