Which of the following statements
best describes the reproduction of both
viruses and cells?
Viruses & cells use mitosis to reproduce.
Viruses & cells must have a host to reproduce
Viruses & Cells must activate polar bodies reproduce
Viruses & Cells need copies of their genetic material to reproduce.
Which labelled part signifies that this cell is eukaryotic?
flagellum
Nucleus
Cell Membrane
All of the following are characteristics of living organisms except:
made of one or more cells
movement
Response to stimulus
Reproduction
Which of the following correctly describes a living organism?
the ability to adapt to changes in their environment
are made of one or more cells
reproduce only with the help of a host
exist without using energy
move freely throughout the environment
Cell theory was created in 1839 and finalized in the 1850s by several prominent scientists. The theory helped biologists move away from the theory of spontaneous generation.
Which statements below accurately describe cell theory?
All organisms are composed of cells.
Cells in a group make up a tissue.
Cells arise from pre-existing cells.
Cells cannot survive individually.
Cells are the most basic unit of organization and structure for organisms.
Which of the following examples is correctly matched with its level of organization?
A squirrel is an organ system
A bone is a type of cell
A liver is a tissue
An eye is an organ
Which characteristic of living things is BEST represented when a tree sheds it leaves during the autumn?
metabolism
reproduction
use of a genetic code
response to external stimuli
In multicellular organisms, cells are organized into tissues, tissues into organs, organs into organ systems, and systems into organisms. Select ALL of the organs from those listed.
blood
brain
eye
leukocyte
muscle
Are viruses alive? The scientific debate continues. Viruses exhibit some characteristics of life, but others are missing.
The MOST obvious reason why scientists still refer to viruses as non-living is that they
do not change over time
do not contain any genetic material
are much smaller than anything alive
are not composed of one or more cells
Viral characteristics include all but ONE:
Most viruses are much smaller than bacteria
Viruses do not contain any nucleic acids
Virus infect all types of life forms on earth
Viruses multiply several ways but always in a host
Unlike a prokaryotic, bacterial cell, a virus.....
has a lipid cell wall
has no genetic material
cannot reproduce on its own
does not contain any organic molecules
A virus is referred to as a particle rather than a cell because structurally it is a
RNA core in a carbohydrate envelope.
nucleus surrounded by a protein coat.
plasmid of DNA surrounded by a capsid.
RNA or DNA core surrounded by a protein coat.
Recall the three tenets of the cell theory. Which of these statements can be used to determine that viruses are non-living?
do not contain nuclei
are not composed of cells
are not able to reproduce
do not contain nucleic acid
