Stem Cell
| Question | Answer |
|---|---|
| Define Cells | microscopic structures that carry on all the functions of life |
| Cells very in ____ and _____ and perform _____ functions. | shape; size; many different |
| Sex cells (gametes) divide by a process of | meiosis |
| An insufficient amount of tissue fluid results in | dehydration |
| Organs and other body parts joined together to perform a particular function is called | organ system |
| Embryonic stem cells have the ability to transform themselves into | any of the body's specialized cells and perform many different functions |
| The study of the processes of living organisms, or why and how they work, is | physiology |
| The part of a cell that condenses to form chromosomes during cell reproduction is the | chromatin |
| A stack of membrane layers that produces, stores, and packages secretions for discharge from the cell is the | golgi apparatus |
| The site for all chemical reactions that take place in the cell is the | cytoplasm |
| Pocketlike folds in the cell membrane that allow large molecules to enter the cell are | pinocytic vesicles |
| The area where ribosomes are manufactured in the cell is the | nucleolus |
| The structures that contain digestive enzymes to digest and destroy old cells are the | lysosomes |
| Pouch-like structures that are found throughout the cytoplasm and filled with a watery substance, stored food, or waste products are the | vacuoles |
| The four main groups of tissues are | epithelial, muscular, connective, nervous |
| The tissue that produces power and movement in the body is | muscle tissue |
| The tissue that lines the intestinal and respiratory tracts and forms body glands is | epithelial tissue |
| Basic unit of structure and function in all living things | cells |
| Outer protective covering of a cell | cell membrane |
| Study of form and structure of an organism | anatomy |
| Controls many cell activities | nucelus |
| Furnaces or powerhouses of the cell | mitochondria |
| Semi-fluid inside the cell | cytoplasm |
| Located inside the nucleus and important in cell reproduction | chromatin |
| Tissues joined together for a particular function | organ |
| Cells of the same type joined together for a common purpose | tissue |
| Study of how disease occurs | pathophysiology |
| What are Induced pluripotent cells? | Induced pluripotent cells are adult cells that have been genetically reprogrammed to an embryonic stem cell-like state by being forced to express genes and factors important for maintaining the defining properties of embryonic stem cells. |
| What are Undifferentiated cells? | A cell that has not yet developed into a specialized cell. |
| Why is the use of stem cells to produce new specialized cells, which can replace a body’s damaged cells and cure a disease, creating such a controversy? | Its creating controversy because a 4-5 day old embryo is still capable of creating a new life but they're using it to produce new specialized cells. Right to life advocates are strongly opposed to stem cell research if they're obtained from embryos. |
