Define the following types of bacteria below:
Gram Positive: Gram-positive bacteria are known as monoderm because they are enclosed by a
single thick peptidoglycan cell wall.
Gram Negative: Gram negative bacteria are known as diderm because they have a
lipopolysaccharide-containing outer membrane that surrounds the cell in addition to their
considerably thinner peptidoglycan cell wall.
Identify the three shapes used to identify bacteria. Provide a representative image and
indicate whether the bacteria are gram positive or negative.
1) spherical (cocci)
2) rod (bacilli)
3) spiral (spirilla)
Explain the symbiotic relationship involved in lichens.
A lichen is a durable symbiotic relationship between a fungus and algae and/or cyanobacteria.
Lichen fungi, like all fungi, require carbon as a food supply, which is given by photosynthetic
symbiotic algae and/or cyanobacteria.
List/describe the appearance of the 3 basic types of lichen and include a picture:
1) Foliose: Compared to other lichen types, foliose lichens are more appealing. They have a flat
shape, are large, smooth, and resemble leaves; they are frequently wrinkled and twisted. It has a
clear upper surface and a bottom surface. With the aid of the rhizoid, this species of lichen is
typically discovered adhering to rocks and twigs.
, 2) Fruticose: These lichens, which are thin and freely branching, are the most significant kinds.
The fruticose lichens are more noticeable and appealing growths that stick out from rocks,
leaves, and tree branches.
3) Crustose: Crustose lichens lack distinct lobes and are flat and thin. Most of the time, they are
found closely clinging to stones, rocks, barks, and tree trunks.
Write three general characteristics of each of the following and a representative image of
the Domain or Phylum.
Domain:
Archaea- the domain Archaea have unusual cell membrane compositions, and some of these
organisms, known as methanogens, have the extraordinary capacity to create methane. Archaea
are widely distributed in nature and are loosely categorized by habitat. Extremophile archaea can
thrive in environments that are unfriendly to other living things.
Bacteria- Bacteria have few big intracellular structures because their cytoplasm lacks membrane-
bound organelles. As a result, they lack a genuine nucleus, mitochondria, chloroplasts, and other
eukaryotic cell organelles such as the Golgi apparatus and endoplasmic reticulum. Bacteria were
originally thought to be simple bags of cytoplasm, but components such as the prokaryotic
