🗑
|
||||
| Golgi vesicle | a membrane-bounded vessicle in the Golgi complex acting as a lysosome or a secretory vessicle in exocytosis
🗑
|
||||
| Golgi complex | modifies, packages, newly synthesized proteins and synthesizes carbohydrates
🗑
|
||||
| Lysosome | function is to destroy worn-out/damaged organelles, get rid of waste materials, and protect the cell from foreign invaders
🗑
|
||||
| Microtubules | move vessicles, granules, organelles and chromosomes via special attachment proteins
🗑
|
||||
| Endoplasmic Reticulum | network of membranous sacs and tubes, active in membrane synthesis and other synthetic and metabolic processes. Has a rough (ribsome studded and smooth)
🗑
|
||||
| Plasma Membrane | membrane enclosing the cell
🗑
|

| Basement membrane | binds the epithelium to underlying connective tissue
🗑
|

| Mitosis | a form of cell division in which a cell divides once and produces two genetically identical daughter cells
🗑
|
||||
| Prophase | chromosomes condense and nuclear envelope breaks down. Spindle fibers grow from centrioles. Centrioles migrate to opposite poles of cells
🗑
|
||||
| Metaphase | chromosomes lie along the midline of the cell. Some spindle fibers attach to kinetochores. Fibers of aster attach to plasma membrane
🗑
|
||||

🗑
|
||||

🗑
|
||||
| Blood capillaries | pass blood from arteries to veins
🗑
|
||||
| Hair folicle | a sac from which a hair grows and into which the sebacous glands open
🗑
|
||||
| Sebaceous gland | secrete an oily substance (sebum) to be used as a barrier against pathogens
🗑
|
||||
| Apocrine sweat gland | responsible for sweat and body odor
🗑
|
||||
| Hair bulb | portion of the follicle that produces hair
🗑
|
||||
