BIOL 4250 Chapter Notes - Chapter 3-4: C4 Carbon Fixation, C3 Carbon Fixation, Suberin
Document Summary
Modes of feeding: bite off and chew food or imbibe liquid nourishment. Mandibles or jaws grind the food, the maxillae guid the food towards the mouth. Cell walls are strengthened by cellulose, lignin, suberin, and callose with sclerenchymatous fibres. Feeding on though plants can wear the mandibles. C3 plants have lower photosynthetic capacity than c4 plants. C4 plants require a lot less water than c3 plants(around half as much) Green plants capture energy through photosynthesis and store this into sugar, the most basic chemical energy source. Classified as allelochemical-non-nutritional chemical produced by an individual of one species that affects growth, health, behaviour, or population biology of another species. Starting from a few basic chemicals, the synthesis of secondary compounds often involves different pathways interconnected in several places. (1)nitrogen containing compounds, (2)terpenoids ,(3) phenolic compounds,(4) acetylenic compounds. Derived from a fairly restricted range of common amino acids(lysine, tyrosine, etc) Act as feeding deterrents and/or toxins to most insects.
