A tiny, nonliving, particle that enters and then reproduces inside a living cell. Has a protein coat that protects an inner core of genetic material, and cannot reproduce on their own.

Viruses are not cells and do not use their own energy to grow or respond to their surroundings. Viruses cannot make food, take in food, or produce wastes. Viruses can only multiply when they are inside a living cell. This makes viruses what?

An organism that provides a source of energy for a virus or another organism.

An organism that lives on or in a host and causes harm. Almost all viruses destroy the cells in which they multiply.

Viruses that have rocket or robotlike shapes. A virus that infects bacteria. Its name means "bacteria eater."

Because viruses are not considered organisms, scientists do not use the two-part scientific naming system to identify them. Viruses may be named after the disease they cause, or the area they were discovered.

After a virus attaches to a host cell, it enters the cell. Once inside the cell, the virus's genetic material takes over many of the cell's functions. It instructs the cell to produce the virus's proteins and genetic material. These proteins and genetic material then assembly into new viruses.

The most common mechanism of reproduction. New viruses rupture the cell immediately.

Another reproductive cycle were the viruses do not take over functions immediately.

The instructions for making new viruses. Located at the inner core of a virus.

Protects the virus.

Unique to each virus, these play an important role during the invasion of a host cell.The shape allows a virus to only attach to certain cells in a host like a key.

A substance introduced in the body to help produce chemicals they destroy specific viruses.

Uses the viral mechanism for infection to deliver new genetic material to cells that need it. Ex. Cystic fibrosis

Once recovered from a viral illness the body becomes _________.

Prokaryotes. Don't have a nucleus, genetic material moves freely in the cytoplasm. Single-celled organisms.

A long, whiplike structure that helps a cell to move.

Spherical, rodlike, or spiral.

Some capture and use the sun's energy as plants do. Others, such as bacteria that live in deep mud use the energy from chemical substances in their environment to make their food.

These bacteria consume other organisms or the food or the food that other organisms make. Consume a variety of foods like milk and meat, or decaying leaves on s forest floor. Serve as decomposers.

Most common mechanism mechanism of reproduction. Bacteria produce asexually in which one cell divides to form two identical cells.

Sometimes bacteria produce sexually. One bacterium transfers some of its genetic material into another some of its genetic material into another bacterium through a thin threadlike bridge.

A small rounded, thick-walled resting cell that forms inside a bacterial cell. It enclosed the cell's genetic material and some of its cytoplasm. Form when conditions are not favorable for bacterial growth.

Lives near plants and converts nitrogen gas to the nitrogen that plants need to grow. This helps plants survive.

Organisms that break down large, complex chemicals in dead organisms into small, simple chemicals.

Eukaryotes that cannot be classified as animals, plants, or fungi. All are eukaryotes and live in moist surroundings. Most are unicellular, some are multicellular. Autotrophic and heterotrophic, some can move and some cannot.

Heterotrophs, most can move to get food, unicellular. Animal like protists except unicellular.

A temporary bulge of the cytoplasm used for feeding and movement.

Protozoans that use one or more long whiplike flagella to move.

Use hundreds of hairlike projections, cilia, to move and feed.

Type of algae, unicellular, glass like cell

Plant-like Protists. Autotrophs that can use photosynthesis & produce much of the world's oxygen. Can be multicellular. Unlike plants because they're unicellular, lack true leaves stems and roots, some can move and some are heterotrophic in addition to autotrophic.

Unicellular algae that can act as heterotrophs in the absence of sunlight. Eyespot used to detect light, flagella that allows movement.

Unicellular algae, have two flagella held in grooves between their plates. Multicellular and some glow in the dark.

Heterotrophs, have cells walls, and use spores to reproduce. Unlike fungus because these are able to move at some point in their life.

A tiny cell that is able to grow into a new organism.

Unicellular or multicellular. Brilliantly colored, live in moist environments, ooze along the surface of decaying materials, feeding on bacteria and other microorganisms.

Eukaryotes that have cell walls, are heterotrophs that feed by absorbing their food, and use spores to reproduce.

Branching, threadlike tubes that make up the bodies of multicellular fungi. The way the fungus looks depends on the structure of these.

Simplest fungi, unicellular, no cell wall.

Multicellular fungi.

Secrete digestive juices into food supply, digest the food, and then absorb food through hyphae that grow into the food source.

What fungus cell walls are made out of.

Fungi produce spores in reproductive structures called __________ __________.

Unicellular yeast undergo a form of asexual reproduction in which no spores are reproduced. Occurs when a small yeast cell grows from the body of the parent cell and then breaks away.

Fungi may act as decomposers and recyclers, or provide food for people. Fungi may help fight or cause disease. Some fungi live in a beneficial relationship with other organisms.

The first, but not only, antibiotic gleaned from fungi. In 1928 Alexander Fleming saw that no bacteria were growing near the mold in his Petri dish.

Chemicals that produce color
