The Cell - SCC BIO 100 CH4
| Question | Answer |
|---|---|
| What does a plant cell have that an animal cell does not? | cell wall, central vacuole and chloroplast. |
| What kind of nucleus does a Eukaryotic cell have? | A defined nucleus. |
| What kind of nucleus does a Prokaryotic cell have? | An undefined nucleus. |
| Control center for animal cell. | nucleus |
| Membrane surrounding nucleus. | nuclear envelope |
| Organelle within nucleus | nucleolus |
| Carries information from DNA into the cytoplasm. | mRNA |
| Nucleic acid component of protein synthesis machinery. | rRNA |
| Membrane network that serves as site of secretory protein synthesis. | Rough endoplasmic reticulum |
| Protein synthesis workbench. | Ribosomes |
| Proteins destined to leave the cell. | secretory proteins |
| Stacks of membrane as in the Golgi complex | cisternae |
| Pinched off pieces of membrane carrying proteins to new destinations. | transport vesicle |
| The budding off and fusing of pieces of membrane system. | endomembrane system |
| Master switching station for proteins after synthesis. | Golgi complex |
| Structure to permit passage of material out of nucleus. | nuclear pores |
| What allows our muscles to contract and our stomachs to digest food? | myosin (muscle cells) |
| This cell has organelles that are developed with greater complexity | eukaryotic |
| Major structural element that moves vesicles within the cell | microtubule |
| This cell is ten times larger than the prokarotic cell | eukaryotic cell |
| This cell has organelles that are developed with greater complexity | eukaryotic |
| Prokaryotic cells are small and lack a distinct what? | nucleus |
| A cell's internal scaffolding | cytoskeleton |
| Organelles lie in this jell-like liquid in a cell | cytosol |
| This part of the cell contains genetic material | nucleus |
| This part of the cell is the complex outside covering | plasma membrane |
| This part of the cell is the site of lipid storage & synthesis | smooth ER |
| This part of the cell is also called "tiny organs" | organelles |
| This part of the cell functions in cellular recycling & waste disposal | lysosomes |
| This part of the cell converts food to energy & requires oxygen | mitochodria |
| This part of the cell contains degradative (digestive) enzymes and is in an acidic environment | lysosomes |
| Smallest cytoskeletol fibers, composed of actin and supports cell movement | microfilaments |
| Most permanent of the cytoskeletal filaments that stabilizes nucleus and other organelles within cytosol | intermediate filaments |
| Cell extension made of microtubules that is hair-like that sweeps material and cell around | cilia |
| Cell extension made of microtubules that propels sperm | flagella |
| Proteins that give structure ad serve as highways for protein transport | cytoskeleton |
| Fibrous protein found in all eukaryotic cells serveing as structural function | actin |
| Protein essential for contraction | myosin |
| Three cytoskeleton components (largest to smallest) | microtubules-intermediate filament-microfilaments |
| This accounts for about 90 percent of the plant cell | central vacuole |
| In the plant cell this acts like a lysosomes, contains digestive enzymes and stores pigments | central vacuole |
| The best-known plastids that capture the sun's energy through photosynthesis; thus storing energy for the plant cell | chloroplasts |
| The cell wall is composed of this starch that provides a rigid structure and controls water absorption | cellulose |
| Contact points between plant cells. | Cell junction |
| Protein clusters that pass through the membranes of adjacent animal cells and create a pore. | Gap Junctions |
| Organization of eukaryotic cells into a structure designed to carry out a specialized function. | tissues |
| Channels for communication between plant cells. | plasmodesmata |
