Exam III Study Set Flashcards
Photosynthesis Input and Output
Input: Sunlight, Water, Carbon Dioxide Output: Oxygen, Sugar
What is a Plant?
Plants Create their own food, plants are sessile, plants are multicellular
Non-vascular plant properties?
No vessels, no seeds, no flowers or fruits
Vascular seedless plant properties?
Vessels, no seeds, no flowers or fruits
Gymnosperm properties?
Vessels, seeds, no flowers or fruits
Angiosperm properties?
Vessels, seeds, flower and fruits
Vascular tissue: Xylem
Main water and mineral conducting tissue
Vascular tissue: Phloem
main food conducting tissue in vascular plants
Transpiration: H2O molecules stick to each other
Cohesion
Transpiration: H2O sticks to walls of vessels
Adhesion
Phototropism
Bending of stems to sources of light with blue wavelengths
Gravitropism
Plants response to gravity. Shoots exhibit negative gravitropism. Roots have a positive response.
Thigmotropism
Plants response to touch
What is a Fungi?
Decomposers or symbiotic, sessile, cells walls made of chitin
Fungi Diversity
Mushrooms, mold, yeasts
Fungi
Heterotrophs
-Digest food externally.
Hyphae
Fruiting bodies
-Spores
Multicellular
-Except for yeast
Life cycle of fungi
Reproduce sexually and asexually. Asexual reproduction: Spores produced through mitosis. Sexual reproduction: Spores produced through a fusion of nuclei from
two separate fungi.
Basidiomycetes
Club Fungi
Ascomycetes
Sac Fungi
Zygomycetes
Bread Molds
Chytrids
Primitive, mostly aquatic, effect frogs
Yeasts
Single‐celled fungus
Reproduce by budding.
Daughter cells are produced as outgrowths of
parental cells.
Ascomycetes, the basidiomycetes, and the
zygomycetes contain yeast species.
Saccharomyces cerevisiae
Beer, wine, and bread
Lichens
Composite organisms.
Fungi and algae or fungi and bacteria.
Mutualism
Mycorrhizae
Up to 90 percent of seed plants live in a
cooperative association with fungi.
Associations of plant roots and fungal hyphae are
called mycorrhizae
