Study Notes
Somatic Cells Overview
- Somatic cells primarily compose the body tissues and organs, excluding reproductive cells.
- Predominantly found in all tissues and organs of multicellular organisms, forming structures like skin, muscles, and internal organs.
- Main role is to support the body's structure and functions, including growth, repair, and maintenance of tissues.
Germplasm vs. Somatoplasm
- Germplasm refers to the reproductive cells (sperm and eggs) involved in heredity and reproduction.
- Somatoplasm encompasses all somatic cells, providing the bulk of the individual’s cellular makeup and sustaining bodily functions.
Characteristics of Mortal Cells
- Mortal cells, like somatic cells, have a limited lifespan characterized by a specific number of divisions they can undergo.
- The Hayflick limit results in mortal cells ultimately ceasing to divide after a set number of mitotic divisions, usually around 40-60 for humans.
Role of Immortal Cells
- Immortal cells, such as germ cells, play a critical role in reproduction, maintaining the continuity of genetic information across generations.
Protoplasm Distinctions
- Protoplasm of germ cells is specialized for reproductive function, containing genetic material and structures necessary for fertilization.
- In contrast, protoplasm of body cells is organized for diverse cellular functions, reflecting the specific needs of tissues and organs.
