Question
Comes from observation. What are we curious about ?
Hypothesis
The answer you think you will find
Predicition
“If/ then” statement .”if my hypothesis is true, then this will happen “
Independent variable
What we change or apply to one group.
Dependent variable
What we observe. Ex. Results after experiment, data found
Controlled variable
Factors that are the same in both experimental groups
Bacterial cells are
Prokaryotes
Do bacterial cells have a nucleus ?
Yes
What bacterial shape is shown here ?
Cocci
What polymer is a unique component of bacterial cell walls ?
Peptidoglycan
Name an antiseptic you expect to be effective against some bacteria
Lysol
What would you expect to see if the bacteria is SENSITIVE to the antibiotic disk ?
Clear zone around disk
What would you expect to see if the bacteria is RESISTANT to the antibiotic disk?
Full on growth around disk
What should you do if you spill a chemical ?
Call the teacher
Where are the safety showers located ?
Outside the hall
What is your instructors name?
Paula Gutierrez
What us one benefit of protists ?
They help produce oxygen
True/false protists are protists are prokaryotic
False
What shape of diatoms are shown below ?
Centric
What shape of diatoms are shown below ?
Pennate
What are 2 characteristics that Green algae share with land plants ?
They have chlorophyll a&b and they’re photosynthetic
What is one benefit of fungi ?
Helps make antibiotics
What is one negative role of fungi ?
They cause disease
Fungi are
Unicellular, Multicellular, and Eukaryotic
Give one piece of evidence that supports the relationship between land plants and green algae.
They can both do photosynthesis
all plants except _______ are sporophyte dominant
Bryophytes
List 2 reasons why are bryophytes are dependent on water
They need it in order for sperm & egg to meet to fertilize and to spread the gametophytes
Is imagine 1 showing male or female gametangia ? What is it called ?
Male antheridia
Identify the image and all structures within image. Know the dominant generation (sporophyte or gametophyte)?
Fern Young Sporophyte: Sporophyte is the clover shaped part, rhizoids are the hairlike structures, and the gametophyte is the bottom/base of structure.
Where do you find sori?
You find sori on the back of a fern leaf.
What does the sorus( sori) contain ?
Spores
Where would you find sori on a plant ?
Back of a fern leaf
What is the function of the seed coat ?
It is a protective coat that surrounds the seed
What happens to the endosperm?
It is found source for embryo , so they shrivel up after leaves are created
From what have the cotyledons developed ?
They have developed from seed leafs
how does the seed facilitate dispersal and survival of the plant ?
It is capable of lasting/surviving longer while in extreme environments
What are the three shapes of bacteria ?
-cocci
-bacilli
-spirilla
What is the ecological role of diatoms, the most important role ?
Most important photosynthesizers in cold, marine waters. They generate 20-50% of Earths oxygen.
Pennate
Bilaterally symmetrical
centric
Radially symmetrical
identify the image and all structures within the image , male or female?
Male: antheridia
identify the image and all structures within the image , male or female?
Female: archegonia
How are spores dispersed within these plants ?
They are dispersed through water because these are from moss plants
Male pine cone
Gymnosperm
Female pine cone
Gymnosperm
flower
Angiosperm
is water required for fertilization in bryophytes, seedless vascular plants, gymnosperms , or angiosperms
Water is required for fertilization in both bryophytes (mosses) and seedless vascular plants (ferns )
What is the method of pollination?
Water, wind, insects, animals
How are spores dispersed?
Spores are dispersed via wind
Fern life cycle
angiosperm life cycle
moss life cycle
Pine life cycle
alternation of generations
parts of the flower
What generation is dominant for each life cycle?
Bryophytes/mosses: gametophyte dominant
What generation is dominant for each life cycle?
Monilophytes/ferns: sporophyte dominant
What generation is dominant for each life cycle?
Gymnosperms/cones: sporophyte dominant
What generation is dominant for each life cycle?
Angionsperms/flowers: sporophyte dominant
When are they haploid?
They are haploid during their gametophyte phase
When are they diploid ?
They are diploid during the sporophyte phase
When does meiosis occur?
Meiosis occurs after the sporangium are grown
When does mitosis occur?
Mitosis occurs in between each phase
conditions that must be favorable for seed germination
Light, temperature, nutrients, and water
Gravitropism
it is a plants response to gravity
Phototropism
it is a plants response to growing towards light
