Cells are the basic building blocks of life. They are the smallest unit of life that can perform all the necessary functions for an organism to survive and carry out its activities. All living organisms, from simple single celled organisms like bacteria to complex multicellular organisms like humans, are composed of cells. Cell membrane: The cell membrane, also known as the plasma membrane, is a thin, flexible barrier that surrounds the cell. It separates the interior of the cell from its external environment and controls the movement of substances in and out of the cell.
The nucleus is a membrane bound organelle that contains the cell's DNA. It serves as the control center of the cell and is responsible for regulating gene expression and directing cell activities.
The cytoplasm is a gel like substance that fills the cell and surrounds the organelles. It consists of water, salts, and various organic molecules. Many cellular processes, such as metabolism and protein synthesis, occur in the cytoplasm.
Organelles are specialized structures within cells that perform specific functions. Examples of organelles include mitochondria (which produce energy), endoplasmic reticulum (involved in protein synthesis), golgi apparatus (involved in protein modification and sorting), and lysosomes (involved in cellular waste disposal).
Deoxyribonucleic Acid (DNA) is the genetic material that carries the instructions for the development, functioning and reproduction of all living organisms. DNA is located in the nucleus of eukaryotic cells and in the cytoplasm of prokaryotic cells. Prokaryotic cells are simple cells that lack a nucleus and other membrane bound organelles. Bacteria and archaea are examples of prokaryotic organisms.
Eukaryotic cells are more complex cells that have a distinct nucleus and various membrane bound organelles. They make up plants, animals, fungi and protists.
These stem cells are derived from embryos that are typically a few days old. ESCs are pluripotent, meaning they can differentiate into any cell type in the body. They have the potential to generate a wide range of specialized cells, making them valuable for research and medical applications. However, their use has been a subject of ethical debate due to the destruction of embryos required to obtain them. Also known as tissue specific or somatic stem cells, these stem cells are found in various tissues and organs throughout the body. Unlike ESCs, adult stem cells are multipotent, which means they can differentiate into a limited range of cell types specific to the tissue or organ they reside in. These cells play a crucial role in tissue repair, regeneration, and maintenance throughout a person's life. The nucleus is a membrane bound organelle that contains the cell's DNA.
