The question asks for the biological term that describes a group of cells with similar structure working together to perform a specific function. This is a fundamental concept in biology related to the levels of organization in living organisms.
Correct Option: D) Tissue
The question asks to identify the French anatomist who first introduced the term 'tissue'. This requires knowledge of key figures in the history of biology and medicine, specifically related to the development of histology.
Marie François Xavier Bichat (1771–1802) was a French anatomist and pathologist. He is widely regarded as the father of modern histology and descriptive anatomy. He introduced the concept that organs are composed of different types of 'tissues' and that diseases affect specific tissues. He classified 21 types of tissues, laying the foundation for the study of tissues as fundamental units of the body, even before the widespread acceptance of cell theory.
C) Bichat — Marie François Xavier Bichat was a French anatomist who is credited with first introducing and popularizing the concept and term 'tissue' in biology and medicine. He defined tissues as distinct structural and functional units, laying the groundwork for histology.
The question asks why multicellular organisms exhibit division of labour. This concept is fundamental to understanding the organization and efficiency of complex life forms. We need to evaluate each option based on the principles of cell biology and organismal organization.
D) Different groups of cells (tissues) are specialised to perform different functions. This statement accurately describes the basis of division of labour in multicellular organisms. Cells differentiate and organize into tissues, organs, and organ systems, each with specific roles, leading to increased efficiency and complexity.
The question asks about the hierarchical organization of living organisms, specifically focusing on cells, tissues, and organs. Understanding the fundamental levels of biological organization is key to answering this question.
Based on this hierarchy, cells combine to form tissues, and tissues combine to form organs.
C) Cells form tissues, and tissues combine to form organs. This statement accurately describes the correct biological hierarchy. Cells are the fundamental building blocks, which then aggregate to form tissues, and different tissues then organize into organs.
The question asks about the main classification of animal tissues. To answer this, one needs to recall the fundamental types of tissues found in animals, which are universally recognized in biology.
Correct Option: D) 4
The question asks to identify the tissue type responsible for covering the body's outer surface and lining internal cavities and organs. This is a fundamental concept in animal histology, focusing on the primary functions of different tissue types.
Correct Option: D) Epithelial tissue is primarily responsible for covering external surfaces (like the skin) and lining internal cavities and organs (like the digestive tract, respiratory tract, and blood vessels). It forms a protective barrier and is involved in various functions such as secretion, absorption, and sensation.
