Column A Column B a. DNA or RNA d. We rely on bacteria and fungi to act as decomposers that keep nutrients cycling through the food chain. In addition to bacteria, nonliving things such as viruses act as disease agents on both plants and animals. Girolamo Fracastoro theorizes that dis- eases are caused by invisible organisms.

Hidden or active vaccine - a weakened virus introduced into a body to induce immunity to a virus. Viral Diseases - smallpox, polio, measles, HIV (AIDS), mumps, influenza, yellow fever, rabies, and common colds. 21 22 Chapter 10 Section 3 Viruses 23 Chapter 10 Section 3 Viruses A Destructive House Guest Viruses attack living cells and turn them into virus factories. Viruses reproduce using the lytic cycle. A Time Bomb Some viruses put their genes into a host cell, but new viruses are not made right away. New cells get copies of the virus s genes when the host cell divides. The genes stay inactive for a long time before they make copies of the virus.

Because many viral diseases do not have cures, it is best to prevent a viral infection from happening in the first place. Vaccinations give your immune system a head start in fighting off viruses. 28 Chapter 10 Bacteria and Viruses Concept Map Use the terms below to complete the concept map on the next slide.

Describe four ways that protists get food.

A parasite invades another organism to get the nutrients it needs. The organism that a parasite invades is called a host. Phytoplankton are the microscopic algae that float near the surface of marine or fresh water.

They have hundreds of tiny, hairlike structures known as cilia. Ciliates use their cilia for movement and also for feeding.
The best-known genus of ciliates is Paramecium. 53 Chapter 11 Section 2 Kinds of Protists 54 Chapter 11 Section 2 Kinds of Protists Heterotrophs That Can t Move, continued Water Molds live in water, moist soil, or other organisms. Some of them are decomposers and thus eat dead matter.
But many are parasites. Slime Molds can move only at certain phases of their life cycle.
Live in cool, moist places in the woods. They use pseudipodia to move around. But when environmental conditions are stressful, they form spores that cannot move. 55 Chapter 11 Section 3 Fungi Objectives Describe the characteristics of fungi. Distinguish between the four main groups of fungi. Explain how lichens affect their environment.

Threadlike Fungi bread mold 2. Sac Fungi Morels-spores in sacs 3. Club Puffballs-spores produced in clubs 4. Imperfect Fungi Penicillium-no sexual reproduction 58 Chapter 11 Section 3 Fungi Characteristics of Fungi, continued Hidden from View Multicellular fungi are made up of chains of cells called hyphae. Most of the hyphae grow together form an underground mass called the mycelium, which makes up the major part of the fungus. 59 60 61 Chapter 11 Section 3 Fungi Characteristics of Fungi, continued Making More Fungi Reproduction in fungi may be either asexual or sexual.
In one type of asexual reproduction, the hyphae break apart, and each new piece becomes a new fungus. Kinds of Fungi Fungi are classified based on their shape and the way that they reproduce. Threadlike Fungi Most threadlike fungi live in the soil and are decomposers. However, some threadlike fungi are parasites. Molds are a threadlike fungi.
Threadlike fungi can reproduce asexually or sexually. Sac Fungi are the largest group of fungi. Sac fungi include yeasts, powdery mildews, truffles, and morels. Sac fungi can reproduce both asexually and sexually during their life cycles. Most of the time, they use asexual reproduction. Club Fungi Mushrooms belong to a group of fungi called club fungi.
Club fungi reproduce sexually. During reproduction, they grow special hyphae that form clublike structures. Nonmushroom Club Fungi Mushrooms are not the only club fungi. Bracket fungi, puff-balls, smuts, and rusts are also club fungi. Imperfect Fungi The imperfect fungi group includes all of the species of fungi that do not quite fit in the other groups. These fungi do not reproduce sexually. Most imperfect fungi are parasites that cause diseases in plants and animals.
But some imperfect fungi, such as Penicillium, are useful. 62 Chapter 11 Section 3 Fungi Types of Fungi Click below to watch the Visual Concept. Visual Concept You may stop the video at any time by pressing the Esc key.
63 Chapter 11 Section 3 Fungi Lichens A lichen is a combination of a fungus and an alga that grow together. The alga actually lives inside the protective walls of the fungus.
Unlike fungi, lichens are producers. The algae produce food through photosynthesis. And unlike algae, the fungi keeps the lichen from drying out.
Lichens are found in almost every land environment. 64 east.mov 65 End of Chapter 11 Show.
