HR Flashcards
- Abdominal cramps
- Diarrhea
- Fatigue
- Excess gas
- Rectal pain while having bowel movement
- Unintentional weight loss
Ameobaiasis
A single celled parasite that causes Amoebiasis
Entamoeba Histolytica
- Asexual reproduction (no sex cells involved, only
the separation of the body into two new bodies)
Binary Fission
Cells with true nucleus
Prokaryotic
Contains single Chromosome
Nucleoid
Eukaryotic
Has true nucleus
is membrane-bound containing
multiple chromatin
Nucleus
The “skin” of the cell. Separates the cell membrane from its external environment.
Cell or Plasma Membrane.
Contains Genetic Material (DNA). The largest organelle in the cell. The “brain” or “governor” of the cell
Nucleus
Contains organelles where most cellular organelles takes place
Cytoplasm
Double membrane of fats and proteins
Nuclear membrane
the colloidal solution
enclosed by the nuclear membrane
Nucleoplasm
Structure for protein Synthesis
Nucleolus
organized structures of DNA and protein found
within cells
Chromatin/chromosomes
Protein factories of the cell: spherical bodies that produce and assemble proteins
Ribosomes
“Transport system” of the cell
- Membranous channels that carry materials throughout the cell
Endoplasmic Reticulum (ER)
Lined with ribosomes; is rough
in appearance (protein synthesis)
Rough ER
no ribosomes (lipid
synthesis)
Smooth ER
Membrane-bound vesicles - of flattened
sacs and stacks (look like pancakes!)
- Temporary stores proteins which can then
leave the cell via vesicles pinching of from
the Golgi
Golgi Apparatus
Contains strong digestive enzymes which
break down worn out organelles or food
Lysosomes
As the “powerhouse” of the cell, it is the
site of cellular aerobic respiration breaking
down of food molecules and turning it into
energy that cells can use in order to
perform life functions)
Mitochondria
Membrane-enclosed spaces for storage of
materials such as food, water, sugar,
minerals, and waste products
Vacuoles
Double-membrane organelles
- Site of photosynthesis, “food factory” of
the plant cell
Chloroplasts
Composed of cellulose and lying just
outside the cell membrane
- Provides cell with both structural support
and protection
- Acts as filtering mechanism
Cell wall
