Question 8

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

Answer 8

Archaea and bacteria

Question 9

What is the gram stain and how is it used in identifying prokaryotes

Answer 9

Determines characteristics of the cell wall. Thick layers are gram-postive and purple and gramnegtive is thin and pink

Question 10

three differences between an animal and plant cell

Answer 10

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.

Question 11

What is the fimbriae

Answer 11

Fimbriae are used by prokaryotes to adhere to one another and to adhere to animal cells and some inanimate objects. The small hairs

Question 12

What is the Pili

Answer 12

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

Question 13

What is the capsule

Answer 13

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.

Question 14

What is the cytoplasm

Answer 14

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.

Question 15

What is the plasmid

Answer 15

Swiggly circle that act as vehicles to introduce foreign DNA into prokaryotes

Question 16

What is the golgi body

Answer 16

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.

Question 17

What is the lysosome

Answer 17

They break down excess or worn-out cell parts in eukaryotes. Look like small herd of circles

Question 18

What is the endoplasmic reticulum

Answer 18

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

Question 19

What is the nucleolus

Answer 19

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

Question 20

What is the vacuole

Answer 20

Bean shape. take in waste products and also get rid of waste products in eukaryotes
