front 11 Eukaryotic cells are typically larger than prokaryotic cells because: | back 11 their internal membrane system allows compartmentalization of functions and extra surface area for nutrient exchanged and placement of enzymes. |
front 12 What is the stinging organelle of paramecium that assists it in capturing large prey? | back 12 trichocyst |
front 13 Which of the following organelles enables the Euglena to be photoautotrophic? Answers: central vacuole lysosomes chloroplasts mitochondria tonoplast | back 13 chloroplasts |
front 14 What is the thick layer that surrounds each onion cell? Answers: interstitial space the plant circulatory system cell membrane cell wall | back 14 cell wall |
front 15 How does the composition of bacterial cell walls differ from that of plant cell walls? Answers: Bacteria have an extensive network of crosslinked teichoic acids in their cell walls, while plant cell walls are composed primarily of cellulose. Bacteria have cell walls composed of peptidoglycan, while plant cell walls are composed primarily of cellulose. Bacteria have cell walls composed of chitin, while plant cell walls are composed primarily of cellulose. Both plants and bacteria have cell walls composed of cellulose; the cellulose fibers are more extensively crosslinked in bacteria than in plant cells.

front 25 Paramecium are heterotrophs. How do they obtain nutrients from their surroundings? through the trichocyst by releasing enzymes outside the cell to digest any available food sources in the immediate environment. through their oral grooves. by use of their contractractile vacuoles | back 25 through their oral grooves |
