Bio 101 #1 Flashcards
Midterm 1
Eukaryotes
Membrane Bound Organelles. Nucleus.
Prokaryotes
Non-membrane Bound Organelles. No Nucleus.
Chlorophyll A
Blue Green
Chlorophyll B
Olive Green
P-Karotene
Yellow-Orange
Xanophyllis
Yellow
Spechtrometry
Rate of Photosynthesis
Describe a method for determining Photosynthetic Rate
Use Spectrometry to predict the rate of light/photosynthesis.
Chromotography
Pigments
Predict How Factors such as Temperature, wavelength, or other variables affect Photosynthesis
Photosynthesis which is how plants make their own food, need correct temperatures or certain warm/high temperatures to activate the chloroplast that kickstart the plant to photosynthesize. Chloroplast
Describe a method for seperating plant pigments, including the theory behind it
Thin Layer Chromatography: Separate compounds in the mixtures. Non Polar + More soluble compounds travels further up the paper.
Develop a hypothesis from your prediction and design an experiment to test your hypothesis
Hypothesis: Educated guess or reasoning for you picking one option or another.
Control Factors in Experiment
Controlled Variable
Independent Factors
What we control; the element or material that we can independently create. For example: Hand Soap that we decide to use
Dependent Factors
What we cannot control; the element or material that is dependent on the independent. For example: The bacteria that grows or does not grow in response to the different hand soap used or in comparison.
Inputs and Outputs of Photosynthesis
Inputs: CO2+ Sun+ Water—-> Outputs: CHO(sugar) + O2
Photosynthesis Definition
Plants use sunlight to generate chemical energy and sugar for food purposes (Make their own food)
State Kingdoms of Life–FAPP and EA
Fungi, Animalia, Plantae, Protista, Eubacteria and Archaebacteria
State Four Protistas: PEAV
Paramecium, Euglena, Amoeba, Volvox
3 Cell Motility
Ciliary Locomotion, Flagellar Movement, Pseduopods
Plant Cells
Larger in Size and has a cell wall and chloroplast
Animal Cells
Smaller than a plant cell. Doesn’t have a cell wall.
Protistan Cells
A eukaryotic cell that is most likely a unicellular organism. Examples include Paramecium, Amoeba, and Euglena.
Advantage of Multicellularity
Chances of Diseases spreading are low. Genetic Diversity!
Advantage of cellularity
Less Complexity–more simple structures
Diffusion
High Concentration to Low Concentration (cells move)
Osmosis:
Water moves from High Potential to Low Potential
Hypertonic
Higher concentration outside of cell that causes water to enter cell and burst.
Plasmolysis
Cellular shrinkage in a hypertonic solution and water flows out of central vacuole
Colonies
2 or more organisms that develop closely to each other (Search a picture as well)
Paramecium Details?
**Looks like Tadpoles and has hair around it
1) Ciliary Locomotion
2)Heterotrophic: does not make their own food
3)Phylum: Ciliophora
4)Moves using Cilia(Tiny hairs)
Euglena Details?
**Green appearance and is a bit tadpoleish round
1) Flagellar Movement
2)Phylum: euglenophyta
3)Photosynthetic and Hetrophobic, does have chloroplast (phagocytosis)
4) Moves using flagella
Amoeba
**Looks weird!! No definite shape
1) Phylum: Amoebeza
2)Unicellular
3)Heterotrophic
4)Move and eat using pseudopods and Phagocytosis
Volvox
*Green Circles with dots inside
1) Phylum: Chlorophyta
2) Photosynthetic and Closely related to plants
3) Colonial: (Green circles with dots inside)
Plantae (Moves to absorb Light)
which is Elodea
*Looks green, and like a mini plant
1) Doesn’t have a cell wall
2)Phylum: Magnoliaphyte
3)Multicellular
4)Photosynthethic
5) Experience plasmyloysis(salt water)
Animalia
**(Cheeky look–kind of wide with one circle in the middle)
1) Human epithelial cells (cheek swab)
2)humans are multicellular, these are individual cells
What are three domains in Lab 2?
Archae, Bacteria, Eukarytic (BAC)
Transmittance
The amount of light that can pass through
Absorbance
The measurement of light that is absorbed
Gram Positive
Appears Purple or Blue
Gram Negative
Red or Pink
