Document Summary
Plants can mess up the animal"s ability to reproduce, by producing. Phototoxins; if animals consume this, the toxins migrate to the skin of the animal making their skin highly vulnerable to uv damage, causing animals to ultimately die. Mustard smell (mustards) is advertising the plant"s toxicity. Plants use aposematic coloring (danger warning) as well. Fruit have this; raw growing fruit has coloring to indicate it is not ready to eat. Phytohormones are used by the plant to get a response from the rest of the plant (plant parts communication) Extrafloral nectarines is produced by some plants to entice ants to come to plant to defend the plant from other predators. Plants can call protectors (such as wasps) and tell them that they are being attacked by caterpillars or other predators. Biggest problem for animals and insects is that water turns to ice. Sometimes animals get stuck in frozen water, then water expands and kills them.
