Symbiosis - Study guides, Class notes & Summaries

Effect of osmotic pressure on cells correct answers The changes in diffusion gradient of water -Higher osmotic pressure, more stress on cell Cells are 80-90% H2O Cell walls resist hypotonic solutions, but few organisms can resist hypertonic solutions Isotonic Solution: No net movement of water particles. Cell membrane is attached to cell wall. Hypertonic Solution: Water particles move out of the cell. Cell membrane shrinks and detaches from cell wall (plasmolysis) Hypotonic ...

What are the 3 types of relationship between parasite, host or vector (if any)? Ans-1. symbiosis= both host & parasite benefit. 2. Commensalism= only the parasite benefits; no harm to host. 3. parasitism= only parasite benefits from relationship; host will suffer & is harmed. True or False.

Ans-The life cycle has two stages1- The motile ameb...

Week 2: Prokaryotic and Eukaryotic Endosymbiosis Animal cell mitochondria • If you chose animal cells, how are mitochondria replicated within eukaryotic cells? • If you chose plant cells, how are chloroplasts replicated within plant cells? How are these processes similar to microbes? • Do endosymbotic relationships still exist today? • What are the advantages and disadvantages of such relationships?

predator-prey relationship correct answers the predator is an organism that eats another organism (the prey). Symbiosis correct answers a close and long-term interaction between two species in an ecosystem. Types of symbiosis include mutualism, commensalism, and parasitism. Mutualism correct answers symbiotic relationship in which both species benefit from the relationship commensalism correct answers A relationship between two organisms in which one organism benefits and the other is u...
