Biology 225: Chapter 35 Q: What are the two systems of a plant and what are they responsible for? A: The Root System (roots) is responsible for absorbing water and minerals from the ground whereas the shoot system (the stems and leaves) is responsible for obtaining light and carbon dioxide from above the ground. Both systems cannot live without the other; the roots require sugar produced by photosynthesis which comes from the shoot system and the shoots require the water and minerals absorbed by the root system for survival. Q: What is the difference between an Angiosperm and a Gymnosperm? A: Vascular Plants with Seeds Gymnosperms Angiosperms

Chapter Forty-One: Animal Nutrition Preface Nutrition: Food being taken in , taken apart, and taken up (Example: Bear chews skin muscles and other part of fish, breaking it down with acid and enzymes in digestive system and finally absorbing it into small molecules in its body) Animals eat other organisms (dead or alive) for energy and also the organic molecules used to assemble new molecules, cells and tissues. There are different types of animal diets; Herbivores: Animals that dine on mainly plants and algae (cattle, sea slugs, termites) Carnivores: Animals that dine on other animals (sharks, hawks,spiders) Omnivores: Animals which consume both plants and animals regularly (humans, crows, and cockroaches)
