1) Organism 1: Chlamydomonas sp
Kingdom: Protista
Subkingdom:
Phylum: Chlorophyta
Order: Chlamydomonadales
Family:
Genus: Chlamydomonas
Defining Characteristics:
- unicellular
- flagella
- small, rapid movement
- chloroplasts
References Used:- Handout-Guide to Fresh Water Microorganisms
- Google images found when I searched for "chlamydomonas sp"
General Observations/Comments:
- movement was difficult to detect
- found in colonies
2) Organism 2: Spirogyra sp
Domain: Eukaryota
Kingdom: Plantae
Subkingdom:
Phylum:
Order: Zygnematales
Family:
Genus: Spirogyra
Defining Characteristics:
- spiral chloroplast arrangements
- cell walls connected in long chains
- able to carry out photosynthesis
References Used:- slide of Spirogyra from lab
- Google images
General Observations/Comments:
- We are unsure as to what the "brown part" of the organism is and whether or not it is actually part of the Spirogyra
- I think it looks like a cigarette
3) Organism 3: Euglena
(very small in the very center of the picture)
Domain: Eukaryota
Kingdom: Plantae
Subkingdom:
Phylum: Euglenozoa
Order: Euglenales
Family: Euglenaceae
Genus: Euglena
Defining Characteristics:
- unicellular
- sometimes green
- motile by flagella
- have photosynthesizing chloroplasts
- red eye spot
- found in fresh and salt waters
References Used:- slide of Euglena in lab
- Google image search when I typed in "Euglena"
- Handout-Guide to Fresh Water Microorganisms
General Observations/Comments:
- move very quickly, difficult to photograph
4) Organism 4: Paramecium sp
(organism in the center)
Domain: Eukaryota
Kingdom: Protista
Subkingdom:
Phylum: Ciliophora
Order: Peniculida
Family: Parameciidae
Genus: Paramecium
References Used:
Subkingdom:
Phylum: Ciliophora
Order: Peniculida
Family: Parameciidae
Genus: Paramecium
Defining Characteristics:
- unicellular
- mostly free-living
- fixed mouth and anal pore
- ciliated
- mainly heterotrophic
References Used:- Google image search of "paramecium"
- Handout-Guide to Fresh Water Microorganisms
- prior knowledge
General Observations/Comments:
- seem to use cilia to gather food into their mouth opening
- cilia curl to allow them to move around as well
It's cool that your Euglena was actually moving. We had two but none of them were moving. I didn't know they could also live in salt waters. Interesting.

ReplyDeleteWell the second organism your group found was a very strange but interesting one, as from my knowledge Spirogyra does not have any brown part. I wonder if that part really belongs to the Spirogyra. What if it belongs to a different organism? Our group also found some brown things similar to yours floating around the sample, which we identified as brown algae, most likely.
ReplyDeleteBy comparing your finding to those of ours, I notice several trend for those organisms in pond water. Protists tend to be the most abundance organism in pond water. Furthermore, regardless of where these organisms belong to which kingdom. The majority of these organisms tend to be autotrophs due to the fact that the majority of them possess chloroplasts which are capable of photosynthesizing. Great results you all have there.
ReplyDeleteGreat that you got a picture of a paramecium, was funny to read about their locomotion and if they run into an object they just reverse their cilia and then try again until they actually get past it. Guess they play a life long match of bumper boats.
