ATI TEAS – BIOLOGY

ATI TEAS – BIOLOGY.1. Which movement requires carrier protein but no direct cellular energy? Facilitated transport 2. Which term denotes the movement of glucose molecules from an area of lower concentration to an area of higher concentration? Active transport 3. Plasmolysis is a term describing? Cellular shrinkage, which occurs when cells are immersed in hypertonic solution 4. The movement of substances from lesser concentration to higher concentration is called? Active transport 5. Which particular structure is present in both eucaryotic and prokaryotic cells? Cell membrane 6. Plant cells differ from animal cells in? The plant cells have a cell wall and animal cells do not 7. Which cell type is characterized by the lack of true nucleus and the absence of membrane-bound organelle? Prokaryotic cell 8. Which organelle is associated with hydrolytic enzymes and is sometimes referred to as a "suicide bag" Lysosomes 9. Pinocytosis is the process of? Enclosing a liquid substance in a membrane and secreting it into the cell 10. The plasma membrane of the eurokaryotic cell determines selectively which substances can enter and leave the cell. Such a membrane is said to be? Selectively permeable 11. What primarily determines the shape of cells that lack cell walls? Microtubule and microfilaments 12. Which pair of organelles is responsible for energy supply to eurokaryotic cells? Chloroplast and mitochondria
