| Question | Answer |
|---|---|
| The theory of eukaryotic cell evolution | symbiosis and endosymbiosis |
| Eukaryotic flagella is more or less complex than prokaryotic | more |
| Eukaryotic flagella have a ___ arrangement | 9+2 |
| Cilia are found in __ cells and some __ cells only | protozoa and animal |
| Glycocalyx purpose (3) | protection, adherence, signal reception |
| How is the cell wall different in a eukaryotic cell | Differs in chemical composition |
| the cytoplasmic membrane is made of (2) | 1- phospolipid bilayer 2- sterols |
| sterols are important in cells that lack what | a cell wall |
| the most prominent organelle of eukaryotic cells | nucleus |
| the site for ribosomal RNS synthesis and collection area for ribosomal subunits | nucleolus |
| chromatin comprises the | chromosomes |
| duplicated chromosomes are separated equally into daughter cells | mitosis |
| the process by which sex cells are created | meiosis |
| series of tunnels used in transport and storage | endoplasmic reticulum |
| ribosomes are put into this cavity and held for packaging and transport | rough er |
| closed tubular network without ribosomes that functions in nutrient processing and in synthesis and storage of nonprotein macromolecules like lipids | smooth er |
| cell site where proteins are modified and then sent to final destination | golgi apparatus |
| involved in intracellular digestion of food particles and in protection against invading microorganisms | lysosome |
| membrane-bound sacs containing fluids or solid particles to be digested, excreted or stored | vacuole |
| energy generators of the cell | mitochondria |
| these membranes hold the enzymes and electron carriers of aerobic respiration | cristae |
| a chemically complex fluid that holds ribosomes, DNA and the pool of enzymes and other compounds involved in the metabolic cycle | matrix |
| photosynthesis machines | chloroplasts |
| protein synthesizers | ribosomes |
| support network | cytoskeleton |
| thin protein strands that attach to the cell membrane and form a network through the cytoplasm | microfilaments |
| long, hollow tubes that maintain the shape of eukaryotic cells without walls and transport substances from one part of a cell to the other | microtubules |
