Understanding Stem Cells, Differentiation, and Specialization in Multicellular Organisms

This resource explores the concepts of stem cells and differentiation, particularly in the production of erythrocytes (red blood cells) and neutrophils from bone marrow, as well as xylem vessels and phloem sieve tubes from cambium. It describes how various cells, including erythrocytes, neutrophils, and plant cells, are specialized for their functions. Additionally, it explains the organization of cells into tissues, organs, and organ systems, highlighting the cooperation required between them for optimal functioning, complemented by diagrams and photographs for better understanding.

Presentation Transcript

  1. Cell Specialisation 1 Definethe term stem cell Definethe term differentiation, with reference to the production of erythrocytes (red blood cells) and neutrophilsderived from stem cells in bone marrow, and the production of xylem vessels and phloem sieve tubes from cambium;

  2. Cell Specialisation 2 Describe and explain, with the aid of diagrams and photographs, how cells of multicellular organisms are specialised for particular functions, with reference toerythrocytes (red blood cells), neutrophils, epithelial cells, sperm cells, palisade cells, root hair cells and guard cells

  3. Cells, Tissues, Organs & Organ Systems Explain the meaning of the terms; tissue, organ and organ system Explain, with the aid of diagrams and photographs, how cells are organised into tissues, using squamous and ciliated epithelia, xylem and phloem as examples Discussthe importance of cooperation between cells, tissues, organs and organ systems
