A flagellum is a whiplike tail that helps organisms living in moist places to move
The characteristics of protists is they are euckaryotic organisms, they are one or
many-celled but do not have the complex organization found in plants and animals, and
some make there own food and other can't. Protists are plantlike, animallike and
funguslike.
A virus is a microscopic particles that make up either DNA or RNA core covered by a
protein coat. Viruses are so small an electrn microscope is needed to see them. Viruses
are not classified in any kingdom because they are not cells. They show almost none of
the characteristics of living things. The classification of viruses are based on it's
shape, the kind of nucleic acid it contains, and the type of organism the virus infects.
The protein coat of a virus gives the particle it's shape. Some viruses have tails, some
are many sided looking like a soccer ball and others look like rods. Others look sphere
shaped. An active virus has these steps:
Attach--- A specific virus attaches to the surface to a specific bacterial cell.
Invade--- The nucleic acid of the virus injects itself into the cell
Copy--- The viral nucleic acid takes control of the cell, and the cell begins to make new
virus particles.
Release--- The cell bursts open and hundreds of new virus particles are released from te
cell. These new viruses go on to affect other cells.
Algae is a plantlike protist. Some are one celled and others are many-celled. All algae
can make there own food because they have a pigment called chlorophyll in there
chloroplasts. Theses are the phylum of algaes:
