Question

What do you call an organization of group of similar cells along with intercellular substances? (a) Organ (b) System (c) Tissue (d) Cell membrane

Short answer

The correct answer is (c) Tissue.

Step-by-step solution

Understanding the Question

The exercise wants to understand the term used to describe an organization of similar cells along with intercellular substances. In Biology, cells and intercellular substances bind together to form various constructs in an organism.

Looking at the Options

The given options are 'Organ', 'System', 'Tissue', and 'Cell Membrane'. An organ is a collection of tissues with similar function, a system is a network of organs working together, and a cell membrane is what envelops a cell and separates the interior of the cells from the outside environment. None of these seem fit the definition correctly.

Choosing the Correct Option

Looking at the remaining option 'Tissue', it perfectly fits the definition. A tissue is a group of similar cells, along with intercellular substances, that performs a specific function in the body.

Key concepts

Biology and the Importance of Tissues

Biology is the fascinating study of living organisms and their vital processes. It delves into the structure, function, growth, and evolution of all living entities. Among its many fascinating topics is the concept of tissue. Tissues are essential structural elements in multicellular organisms. They consist of groups of similar cells working together to perform a specific function.
A deeper understanding of tissues is crucial because they play a significant role in forming organs, which then work collectively as part of various systems within an organism. Knowing more about tissues helps us understand how complex life forms function, how they maintain homeostasis, and how they react to different stimuli and repair themselves. This forms the basis of much research in medical biology as it can lead to insights into diseases and their treatments.

Cell Organization and Tissue Formation

Cell organization refers to how cells are structured and grouped to carry out specific tasks. In multicellular organisms, cell organization is particularly vital as it determines how tissues and organs form and function. This organized structure enables cells to work in unison, performing tasks too complex for individual cells.
Cell differentiation plays a key role here. Differentiation is the process by which unspecialized cells become specialized for specific functions. This specialization allows for the formation of tissues, where groups of similar cells and intercellular substances unite to perform unique roles. For example, muscle tissue is composed of muscle cells that contract to allow movement, while nerve tissue consists of neurons that transmit signals throughout the body. Each type of tissue is crucial to the organism's survival, emphasizing the significance of cell organization in maintaining life.

Intercellular Substances and Their Functions

Intercellular substances are non-cellular materials present between cells in a tissue. They have various important roles in supporting and connecting cells within the tissue. These substances, which can be in the form of fluids, fibers, or gels, help maintain the structure and integrity of tissues.
Among their functions, intercellular substances facilitate the exchange of nutrients and waste between blood and cells, provide cushioning and support to keep cells in place, and protect tissues from mechanical stress. For instance, the intercellular matrix in connective tissues is rich in collagen fibers, which provide strength and flexibility.
Understanding intercellular substances gives insight into how tissues remain robust and functional over time. This knowledge aids in the development of medical treatments and interventions by highlighting the importance of a supportive environment for cells.
