8th Grade Botany

Test 1-Viruses/Fungus/Bacteria

Virus a tiny non-living particle that enters and reproduces inside a living cell
Bacteriophage a virus that infects bacteria, which actually means "bacteria eater
Host organism that has been infected by a virus/bacteria and is used as a source of energy
Parasite organisms that live on or in a host and causes harm to the host
Mycelia the furry structure that is produced when the spores germinate
Symbiosis when multiple orgamisms live together in a relationship that benefits both
Eukaryote organisms whose cells contain a nucleus
Prokaryote organisms whose cells lack a nucleus
Which is larger, a virus or a cell? Virus
What does a viruses genetic material contain? instructions for making new viruses
How are viruses similar to organisms? They are able to multiply
How are viruses different? Viruses are not cells and do not use their own energy to grow or to respond to their surroundings. Viruses cannot make food nor take in food. They do not produce a waste product.
What basic structure do all viruses share? All viruses have two basic parts: a protein coat that protects the virus and an inner core made of genetic material.
How do active and hidden viruses differ in their quest to multipy? After entering a cell, an active virus immediately goes into action. The virus's genetic material takes over cell functions and the cell quickly begins to produce the virus's protein and genetic material. Then these parts assemble into new viruses.
How do active and hidden viruses differ in their quest to multipy? In hidden viruses the virus does not appear to affect the cell's functions and may stay inactive for years. Each time the host cell divides, the virus's genetic material is copied along with the host's genetic material.
What are the 4 main reasons that biologist consider viruses to be non-living? 1. Viruses are not cells 2. Do not use their own energy to grow or respond to their surroundings 3. Viruses cannot make food nor can they take in food 4. They do not produce a waste product
Fungi (do/don't) have a nucleus and therefore are considered (Eukaryotes/Prokaryotes). Do, Eukaryotes
