Some Viruses can be crystallized and stored in a jar for years. Viruses are identified as living things All viruses contain hereditary material. The core of a virus is surrounded by a protein coat. True Some viruses can cause diseases. True False (non-living) Edward Jenner developed the first vaccine. True True The shape of all viruses is spherical like a basketball. False (all different shapes) True Latent viruses can hide inside host cells for a long time. True True Gene Therapy substituting correctly coded hereditary material for a cell’s incorrect hereditary material True True A virus can reproduce without a host. False (needs a host cell) The protein coat of a virus gives the particle its shape. True What is a vaccine solution made of? Killed virus particles or weakened viruses The four steps an Active Virus takes to reproduce: Attach Invade Copy Release A light microscope having two lenses. Compound Microscope Viruses cause disease in protists, fungi, bacteria, plants, and animals. Viruses are often named for the diseases they cause. If the eyepiece lens of a microscope has power of 10x and the objective has a power of 43x – The _____ is 430x The surface of whole objects can be examined with a _______ electron microscope. A _______ is used to see what is inside of a cell. A _______ microscope lets light pass through an object and then through two or more lenses. total magnification The electron microscope uses a _______ magnetic field to bend electrons. scanning If you wanted to look at an earthworm, you would use a _________ light microscope. stereoscopic transmission electron microscope (TEM) The _______ states that organisms are made of cells, and cells come from pre-existing cells. cell theory Light (compound) The eyepiece lens usually has a power of _______. 10x SEM stands for _______. Before the discovery that cells _______ to form new cells, people thought life occurred spontaneously. In a light microscope, the lenses _______ the image and _______ light toward your eye. Made the first compound microscope. Scanning Electronic microscope The first person to use the term “cell” was looking through a microscope at a slice of _______. cork divide A magnifying glass works like a _______ microscope because it has only one lens. simple bend Observed that every cell comes from a cell that existed before Rudolph Virchow Zacharias Janssen Called box-like structures in cork “cells” Robert Hooke enlarge Organelles that release energy mitochondria for the cell. Groups of similar cells that do the same work. tissue Structure that forms outer boundary of cell cell membrane Gel-like material inside the cell membrane cytoplasm organ Stacks of sacs that package and move proteins Golgi bodies ribosome A folded membrane that moves material in cells. endoplasmic reticulum Different types of tissues that work together to do a job Where proteins are made. Structure that directs the cell’s activities. Chromatin is made up of _______. Cell wastes are digested in organelles called _______. Plant cells differ from animal cells because plant cells have _______. nucleus Prokaryotic cells do not have any _______. membranecovered organelles Protein and DNA The structures within the cytoplasm of eukaryotic cells are _______. organelles lysosomes Water, food, and waste products are stored in the cell’s _______. vacuoles cell walls Plants can trap light energy in organelles called _______. chloroplasts Plants can trap light energy into chemical energy in the form of _______. Groups of similar cells in a tissue _______. sugar The shape of a cell tells you something about its _______. job do the same kind of work A leaf functions as a(n) _______ to make food for a plant. organ Structure that directs the cell’s activities. Chromatin is made up of _______. Cell wastes are digested in organelles called _______. Plant cells differ from animal cells because plant cells have _______. nucleus Prokaryotic cells do not have any _______. membranecovered organelles Protein and DNA The structures within the cytoplasm of eukaryotic cells are _______. organelles lysosomes Water, food, and waste products are stored in the cell’s _______. vacuoles cell walls Plants can trap light energy into chemical energy in the form of _______. chloroplasts
