LAB 1:Biological Life at AU

Lab 1, we examined the organisms of the same species that were prime examples of evolution. We dealt with Chlorophyta, a green algae group. We measured the number of cells of Chlamydomonas, Gonium, and Volvox; and examined other characteristics of the group of organisms.

Cells Size
Chlamydomonas125Isogamous
Gonium10Oogamous
Volvox180Oogamous

Great job! Very complete information and well documented. ML

Lab 2: Identify Algae and Protists

Lab 2 focused on using a dichotomous key to identify unknown organisms and also examine algae and protists from our transect. Before all that we brushed up information on Unicellular Eukarya .

Bio_1.png

Peranema: 20um

Colpidium Sp: 50um

Volvox: 350um


BIO2.png

Brown Algae: 10um

Bursaira Truncatbella: 500um

Chlamydomonans: 5um

Peranema meets the needs of life because it can grow, reproduce, uses oxygen, and responds to its environment.

If the Hay Infusion Culture grew for another two months, the organism that are currently there would multiply and adapt to the new enivromnet , the smell would get stronger. Fungi and bacteria will start to appear. Temperature would affect the community of samples.

Very good, well organized and documented. Keep up the good work! ML

Lab 3: Microbiology and identifying Bacteria with DNA Sequences


-The strength of the smell has decreased in the Hay Infusion

- The water has become a bit cloudy

-The water also evaporated quit a bit because there is less water than before

The appearance and smell in the Hay Infusion have decreased from week to week because the microorganisms have multiple and adapted to their new environment.

The plates without the antibiotic had many colonies appear compared to the plate with antibiotic had one or few appear. The bacteria in the plate is not resistance to tetracycline. There were 3 that were unaffected by the antibiotic.

Tetracycline inhibits protein synthesis by preventing the attachment of aminoacyl-tRNA to the ribosomal acceptor (A) site. Tetracyclines are broad-spectrum agents, exhibiting activity against a wide range of gram-positive and gram-negative bacteria, atypical organisms such as chlamydiae, mycoplasmas, and rickettsiae, and protozoan parasites.

Lab 4: Plantae and Fungi

Purpose


The purpose of this lab was to study the different characteristics of plants and then characterize the plant life living in our transect (transect 2). PCR reactions were ran and sequenced for the genes of the bacteria that were collected the last lab. Lastly, the Burlese funnel was put together to collect invertebrates for lab 4. Invertebrates and the plants will represent our ecosystem

Lab 5: Invertebrates

Purpose: Help understand the importance of Invertebrates and learn how simple systems evolved into more complex systems.

Methods:

Berlese Funnel Set up:

1. Pour 25mL of 50:50 ethanol/water Solution into a 50mL conical tube 2. Place a piece of screening material into the bottom of the funnel 3. Then place leaf litter in the top of funnel 4. Next place funnel on to ring stand 5. Place a lighted 40 watt lamp above the funnel, 1-2 inches from the top of the leaf litter 6. Cover everything with foil 7. Leave for a week


Movement of worms: Quick, springing, stationary and almost elastic

Invertebrates:

Bees: 1.5cm Centipede: 30cm Small Crab: 1.5cm Spider: 4cm Millipede: 35cm


Invertebrates found in Transect
