| Question | Answer |
|---|---|
| cytoplasm | the internal living material of the cell |
| phospholipids | substance that forms the framework of the plasma membrane |
| **plasma membrane function (check that answer is accurate | **acts as the outer boundary of the cell; regulates what enters and leaves the cell; identifies a cell as belonging to an individual |
| organelle | tiny structure found in the cytoplasm |
| ribosomes | organelles that float in the cytoplasm and attach to the endoplasmic reticulum |
| lysosome | the interior of this organelle contains various kinds of enzymes capable of breaking down all of the main components of the cell |
| golgi apparatus | this organelle is involved in processing and packaging proteins for export out of the cell |
| mitochondria | often referred to as the "power plant" of the cell, this organelle is the site of ATP production |
| diffusion | the net movement of molecules from a region of higher concentration to a region of lower concentration |
| microvilli | these are small fingerlike projections on the plasma membrane that increase surface area and aid in absorption |
| osmosis | the net movement of water molecules from a region of high concentration to a region of lower concentration through a selectively permeable membrane |
| ion pump | a(n) active transport process |
| phagocytosis | the cell process that involves microorganisms or other large particles being engulfed |
| nitrogen base | the component that distinguishes one DNA nucleotide from another |
| filtration | process is the movement of water and solutes through a membrane by the force of hydrostatic pressure |
| transcription and translation | two processes of protein synthesis |
| TAGCC | if one side of a DNA molecule had a nucleotide sequence of ATCGG, the opposite side of the molecule would have this nucleotide sequence |
| interphase | mitosis is subdivided into four phases except |
| centrioles | these are paired organelles that are important in the moving of chromosomes during cell division |
| transfer RNA | this type of RNA molecule moves from the nucleus to the ribosoms |
| messenger RNA | this type of RNA molecule carries amino acids to the ribosome to help in protein synthesis |
| metaphase | during this phase of mitosis, the chromosomes are aligned across the center of the cell |
| telophase | this is the last phase of mitosis |
| anaphase | during this phase of mitosis, chromosomes are pulled to opposite ends of the cell |
| prophase | spindle fibers form during this phase of mitosis |
