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-Two: Circulation and Gas Exchange Preface All animals must exchange substances with the environment. Unicellular animals may directly exchange with the environment. Nutrients and oxygen enter through the plasma membrane to the cytoplasm while carbon dioxide and metabolic by-products exit from the cytoplasm through the plasma membrane. Multicellular organisms cannot exchange material at the cellular level and therefore rely on specialized systems that carry out exchange with the environment and transport the material from the sites of exchange to the rest of the body. Concept One: Circulatory systems link exchange surfaces with cells throughout the body

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)

Chapter Forty: Basic Principles of Animal Form and Function Preface A jackrabbit?s ear not only provide the animal with an acute sense of hearing but also help it shed excess heat via the blood flowing in each ears network vessels which transfers heat into surrounding air. When air is warmer than jackrabbit (exceeding 40? C), the jackrabbit?s pink ears turn pale, reflecting a narrowing of the blood vessels in response to the environment allowing their ears to absorb heat without affecting the rest of the body. Once the air cools, blood flow increases again, helping to release heat. Anatomy: Study of biological structure Physiology: Study of biological function
