Active Transport
1. Active Transport- the movement of substances across cell membranes from low to high concentrations, requiring energy and proteins that act as carriers
2. Adenosine triphosphate- chemical compound consiting of one molecule of adenine, one of ribose, and three of phosphoric acid
3. Anaphase- a late stage of cell division during which chromosomes move to the poles of the spindle
4. Benign-nonmaligment
5. Cell-basic unit of structure and function for all living things
6. Cell membrane-the membrane that surrounds the cytoplasm, through which substances pass in and out of the cell
7. Centriole-two cylindrical orgenelles found near the nucleus in a tiny body called the centrosome
8. Centrosome-tiny area near the nucleus of an animal cell
9. Chromatid-each strand of a replicable chromosome
10. Chromatin-DNA and protein material in loose and diffuse state
11. Chromosome- nuclear material that determines hereditary characteristics
12. Cloning- duplication of biological material
13. Cytoplasm-protoplasm of the cell body, excluding the nucleus
14. Cytoskeleton-internal framework of the cell consisting of mictotubules, intermediate filaments and microfilaments
15. Diffusion-molicules move from higher concentration to lower concentration
16. Endoplasmic reticulm-transport system of cells
17. Equilibrium- a physical state or sense of being able to maintain bodily balance
18. Filtration-movement of water and particals across a semipermeable membrane by a mechanical force such as blood pressure
19. Genetic engineering-the ability ti snip, rearrande, edit, or program DNA
20. Golgi Apparatus- a membranous structure in the cytoplasm of cells consisting of layers of flattened sacs and functioning in the processing and transporting of proteins
21. Hypertonic solution- a solution in which water molecules are moving out of a cell, causing it to shrink

22. Hypotonic solution- A solution in which water molecules are moving into the cell, causing it to swell
23.

    7. Humans' cells are in isotonic solution that keeps equal number of solutes both inside and outside of the cell. If the cell is put in a hypotonic solution, water will move into the cell. This causes the cell to burst and die. On the other side, if you put the cell in a hypertonic solution, water will move the outside of…

    Cells must move materials through membranes in order to maintain homeostasis. The cellular environment is aqueous, indicating that the solutes dissolve in the solvent, water. When a cell is hypertonic, or hypotonic, to its surroundings, it tries to make concentration of solution inside and outside itself equal. However, the solutes are too big to pass the cell membranes without the help of channel proteins, or transport proteins. Water may freely pass through the membrane by osmosis, which requires no energy. Thus, the cell starts to take in, or release, water until it is isotionic to its…
