Prokaryotes and Eukaryotes Flashcards
What is a eukaryotic cell?
Cells that have a nucleus and membrane bound organelles
Mitochondria is
Organelles in cells that produce energy for a cell
Examples of Eucaryotes include:
- Protist
- Plants
- Fungi
- Animals
Prokaryotic cells
‘Primative’ cells with a simple structure, lacks a nucleus and membrane bound organelles.
Examples of prokaryotes include:
Archea and Eubacteria
( have pili and flagella to help them move around)
Are eukaryotes unicellular or multicellular?
multicellular or unicellular
Are prokaryotes unicellular or multicellular?
unicellular
Describe prokaryotic DNA:
- floats in the cytoplasm
- Small and circular
Describe eukaryotic DNA:
Found in the nucleus
Straight
Have large amounts of DNA
what are all of the internal structures of eukaryotic cells that are membrane bound called?
organelles, and they all have different functions within the cell.
What is the aim of the investigation to examine prokaryotic and eukaryotic cells?
Aim: to examine and compare a variety of prokaryotic and eucaryotic cells using a light microscope. (wet mount prac)
Identify two limitations of using a light microscope.
Only certain
structures (such as the cell membrane, nucleus, cytoplasm and chloroplasts) are large enough to be viewed
using the microscopes available in school laboratories. For more details of other structures in a cell, electron
micrographs need to be used.
how do you calculate the magnification of a light microscope?
total magnification = magnification ocular lens x magnification objective lens
What features do the two different types of cells share?
cell membrane
cytoplasm
ribosomes
