Cell Anatomy 1a
Chapter 1-4
| Question | Answer |
|---|---|
| hereditary DNA aka nucleoplasm and nucleolus | Nucleus |
| are cytosol (fluid part), organelles (little organs), and inclusions | Cytoplasm |
| is the outer barrier of the cell | plasma membrane |
| are uncoiled chromosomes they are 50% protein, 40% DNA, and 10% RNA | Chromatin |
| When chromatin condenses it becomes visible in the light of a microscope and is called | Chromosomes |
| appear prior to cell division. | Chromosomes |
| is the skin of the cell which forms the outer barrier. It is made up of 4 main components phospholipid bilayer, plasma membrane proteins, carbohydrate chains, and cholesterol | plasma membrane |
| stops electrically charged particles from passing through (includes all water dissolving substances). It is the main constituent of the plasma membrane | phospholipid bilayer |
| (big purple thing) regulates the passage of substance in and out of cells. They are attachment sites for cytoskeleton. They act as enzymes. They form attachment with other cells | plasma membrane protein |
| (green things sticking out of cell) act as antennae for extra cellular signals | carbohydrate chains |
| stirs up the phospholipid bilayer preventing it from gelling up | cholestorol |
| is double membrane lined. The powerhouse of the cell. Vast majority generated. The reason we take in O2. It has its own DNA. Replicates on its own | mitochondria |
| protein factories. They are made of protein and RNA. Site of protein synthesis. They are found in two locations free in the cytoplasm and part of the ER. Consist of two subunits made in the nucleolus large subunit and small subunit | ribosomes |
| There is two types of ____________ ___________ rough (with ribosome’s) and smooth (functions are lipid metabolism and detoxification). | endoplasmic retiular |
| protein modification and sorting. They are a series of flattened membranes. Produces different packages, secretary vesicles, cell membrane components, and lysosomes | golgi apperatus |
| are membranous organelles, digestive enzymes, low pH, and are known as “little stomach”. | lysomes |
| detoxify harmful substances. They breakdown free radicals. | peroxisomes |
