Cell Differentiation and Reproduction
Cell Differentiation
The process by which cells become specialized is call cell differentiation. The goal is to maintain complex multicellular organism
Stem cells are undifferentiated cells
Organs
Organ Systems: Group of organs that work together. Depend directly or indirectly, on all the others
Organs: collections of tissues with similar functions
Tissues
Epithelial tissue forms the protective outer layer of the skin, the lining of organs, and the internal body cavities.
Nervous tissue carries messages to and from the brain.
Connective tissue provides structure, support and connects other types of tissues together.
Muscular tissue causes movement.
Cell Reproduction
Asexual reproduction
The creation of offspring from a single parent
Offspring are genetically identical to the parent cell.
Examples:
Mitosis
Cloning
Binary Fission
Sexual Reproduction
Joining of two different parent specialized cells called gametes.
The offspring that result are genetically unique because they have a mixture of genes from both parent cells.
Examples:
Fertilization
Gametes
Meiosis
