| Question | Answer |
|---|---|
| The English microscopist who first described cells under the microscope in 1665: | Robert Hooke |
| the theory clearly states that the cell is the basic unit of all life | The Modern Cell Theory |
| tiny "organs" within a cell | organelles |
| Be able to label the organelles in a cell | see handout |
| the brain of the cell | nucleus |
| the fluid matter within a cell which forms the framework of support | cytoplasm |
| the power plant of the cell, providing 95% of the body's energy needs | mitochondria |
| the garbage truck of the cell by cleaning up debris and other waste | lysosome |
| the road system within a cell responsible for transporting nutrients throughout the cell | endoplasmic reticulum |
| the packaging plant of the cell responsible for surrounding protein with a vesicle so it can be transported out of the cell | golgi body |
| cells that are able to reproduce themselves | asexual reproduction |
| Interphase | the cell is preparing to divide. DNA and centrosome's duplicate themselves |
| Prophase | cell begins to divide. Centrioiles begin to omove to opposite ends |
| Metaphase | the chromosomes line up in the middle of the cell |
| Anphase | the chromosomes split and the spindle fibers pull them apart |
| Telephase | two nuclei form. mitosis ends |
| Connective Tissue | holds things together; provides structure and nutrients; defends against infection |
| nervous tissue | slender white cords that carry information from one part of the body to another |
| Epithelial tissue | a covering and lining tissue; covers the body surface and lines the interior of the body cavities |
| Muscle tissue | consists mainly of dozens of slender, rod-shaped muscle fibers running parallel to one another |
| Integument | body covering |
| epidermis | the outermost layer of the skin formed by epithelial tissue |
| Dermis | dense irregular connective tissue that forms the deep layer of the skin |
| hypodermis | loose connective tissue underneath the dermis which connects the dermis to muscle or bone |
| squamae | dead, keratin stuffed scales |
| melanin | made in the skin to absorb ultraviolet rays and protect the skin |
| Vitamin D Synthesis | synthesized in the deepest cells of our skin by a reaction to UV light. Vitamin D helps absorb calcium and phosphorus and helps our bones to grow. |
| major function of hair | sensory reception |
| what glands in the skin play an essential role in regulating body temperature | sweat glands |
| what glands lubricate the skin and hair follicles | sebaceous glands |
