Plantlike Protests: – commonly referred to as algae – have organelles called chloroplasts which contain chlorophyll that help them carry out photosynthesis – are authors therefore they use photosynthesis for nourishment – there is 4 different phyla: solenoids, chromospheres, diatoms, and tintinnabulations – these algae can be given a variety of colors because they have accessory pigments that absorb light Hypothesis: If organisms are in the kingdom Prosiest, then they share common structures.
3 microscope slides water 1 sample of Volvo 1 sample of euglena 1 sample of Spirogyra 3 cover slips 3 medicine droppers 1 microscope 1 piece of paper Procedure: 1.
Using the first medicine dropper, take a sample of euglena and place it on the first microscope slide. 2. Place a cover slip over the sample of euglena and onto the slide. 3. Observe the euglena slide under the low power objective first. 4. Sketch the euglena and note observations. 5. Observe the euglena under the high power objective and note observations at this higher magnification. 6.
Darken half of the viewing field by placing paper ever the microscope’s light source or by rotating the diaphragm.
7. Prepare a wet slide mount for the sample of Spirogyra by repeating steps 1-2. 8. Observe the Spirogyra under scanning, low power and high power, then note the observations. 9. Sketch the Spirogyra. 10. Prepare a wet slide mount for the Volvo. 11. View the Volvo under scanning and low power. 12. Sketch the Volvo. Results: The drawings of the three samples of algae are stapled to this lab on a separate piece of paper.
Under the microscope, the Volvo appeared as small, light green spheres with spikes on them.
It moved around in a quick, bouncy way, while rotating. The Spirogyra were long shapes with small blobs inside of them. The euglena was a blob shaped organism with smaller shapes inside of it. It moved slightly and slowly. We were able to identify the chloroplasts and the sexpot.
The hypothesis was proven true. Organisms in the kingdom Prosiest share many common structures. First off, all protests are eukaryotic; therefore, they have a nucleus. Plantlike protests contain chlorophyll and carry out photosynthesis. Some algal protests use tail-like flagella in order to move around their watery environment.
