Field of View, Unit Conversions and Pro/Euk Flashcards
If there are 10um cells that has 4 across. What is the field of view?
40um. 4x10
If the Field of View is 66 but the cells are 11um. How many cells are there?

hm stands for what
hectometers
Name four distinct characteristics of prokaryotes
- non-membrane bound
- flagella
- nucleoid
- less complexity
Name four distinct things about eukaryotes
- membranebound
- nucleus
- mitochondrion
- more complex
The prokaryotes make up two of the three domains of living things. What are these domains and name some examples tht are in each domain
Archaea and bacteria
What is the gram stain and how is it used in identifying prokaryotes
Determines characteristics of the cell wall. Thick layers are gram-postive and purple and gramnegtive is thin and pink
three differences between an animal and plant cell
Plant cells have a cell wall, but animals cells do not. …
Plant cells have chloroplasts, but animal cells do not. …
Plant cells usually have one or more large vacuole(s), while animal cells have smaller vacuoles, if any are present.
What is the fimbriae
Fimbriae are used by prokaryotes to adhere to one another and to adhere to animal cells and some inanimate objects. The small hairs
What is the Pili
Pili are short, hair-like structures on the cell surface of prokaryotic cells. They can have a role in movement, but are more often involved in adherence to surfaces
What is the capsule
promote bacterial adhesion to surfaces or interaction with other organisms; act as a permeability barrier, as a defense mechanism against phagocytosis and/or as a nutrient reserve.
What is the cytoplasm
Cytoplasm. The cytoplasm is the gel-like fluid inside the cell. It is the medium for chemical reaction. It provides a platform upon which other organelles can operate within the cell.
What is the plasmid
Swiggly circle that act as vehicles to introduce foreign DNA into prokaryotes
What is the golgi body
A stack of small flat sacs formed by membranes inside the cell’s cytoplasm (gel-like fluid). The Golgi body prepares proteins and lipid (fat) molecules for use in other places inside and outside the cell.
What is the lysosome
They break down excess or worn-out cell parts in eukaryotes. Look like small herd of circles
What is the endoplasmic reticulum
The endoplasmic reticulum can either be smooth or rough, and in general its function is to produce proteins for the rest of the cell to function. swiggles near nucleus
What is the nucleolus
The nucleolus is a dynamic membrane-less structure whose primary function is ribosomal RNA (rRNA) synthesis and ribosome biogenesis. There are found within cell nucleus
What is the vacuole
Bean shape. take in waste products and also get rid of waste products in eukaryotes
