Biology Review L.14.7 – Plant Structures and FunctionsRelate the structure of each of the major plant organs and tissues to physiological processes.
Explain how the structures of plant tissues and organs are directly related to their roles in physiological processes.Slide2
How are the structures of plant tissues and organs directly related to their roles in physiological processes?
Roots-
Anchor plants, and absorb, transport, and store nutrients from the soilStem- Support plants, transport materials, and provide storage. Leaves- Main site of photosynthesis, area of gas exchange through stomataFlower- Contain the plants reproductive organsSlide3
sugars
water and mineral nutrients
How are the structures of plant tissues and organs directly related to their roles in physiological processes?
Ph
loem-
Carries sugar made in
ph
otosynthesis
Xylem-
Carries water and dissolved nutrients from soil
Pollen-
Male reproductive cell in plants (plant sperm).
Stomata-
tiny holes on the surface a leaf that o
pen and close to allow gas to come in (CO2) and out (H2O and O2).Slide4
Biology Review L.17.9 – Trophic LevelsUse a food web to identify and distinguish producers, consumers, and decomposers. Explain the pathway of energy transfer through trophic levels and the reduction of available energy at successive trophic levels.
Explain how organisms cooperate and compete in ecosystems.
Describe the energy pathways through the different
trophic levels of a food web or energy pyramid.Describe the potential changes to an ecosystem resulting from seasonal variations, climate changes, and/or succession.Analyze the movement of matter through different biogeochemical cyclesSlide5
How do organisms cooperate and compete in ecosystems? (give examples of each)
Predator- Prey relationships
Competition for space, food, shelter, mates, etc. Slide6
How does energy move through a food web or energy pyramid? (draw and explain)
Energy is transferred from one organism to the next through consumption or decomposition.
Only 10% of the available energy is transferred to the next trophic level.Arrows in food webs show the flow of energy.Slide7
How can ecosystems be changed by seasonal variations, climate changes and succession? (give example)
Succession-
The changing of an ecosystem. Occurs when one species replaces the next until a climax community is reached.
Primary Succession- Occurs when there has never been life on a piece of land before. Ex: Glacier retreating, Volcanic eruption Secondary Succession- Occurs after an event disturbs a preexisting ecosystem.Ex: Forest fire, hurricane, etc. Slide8
How does matter move through different biogeochemical cycles (such as carbon through the carbon cycle)?
Water Cycle-
evaporation, transpiration, condensation, and precipitation
Carbon Cycle- photosynthesis, cellular respiration, burning fossil fuels, and decompositionSlide9
