Observation: The grass is greener closer to the sprinkler than further away from it.
Write a question, hypothesis and prediction.
Q: Why is the grass is greener closer to the sprinkler than further away from it?
H: Grass closer to the sprinkler receives more water than grass far away from the sprinkler.
P: If the sprinkler is turned on once per day, grass near the sprinkler will stay green and grass far away will turn brown.
What environment do Bryophytes need to grow?
Acidic
What are the characteristics of a desert environment?
- Hot and dry
- Annual rainfall less than 25 cm/year
- Direct sunlight
- Extreme temperature shifts from day to night
-Sandy soil that don't hold water well
- Strong winds
What is the ecological importance of gymnosperms?
1) Provide food and habitat for wildlife
2) Forests prevent soil erosion
3) Reduce greenhouse-effect gasses
Draw and label the Rhizome of a plant.
What are the 4 phyla in the plant Kingdom?
1) Bryophyte
2) Pteridophyte
3) Gymnosperm
4) Angiosperm
What are 3 roles of Bryophytes?
1) Intercept rain drops - prevents wash outs
2) Pioneer plant (is the first organism to populate an area)
3) Shelter and food
How have desert plants adapted to the desert environment?
- Store water in fleshy stems
- Thick waxy skin
- Spines protect water
- Shallow roots to collect water
- Flower at night
- Slow growth
Draw and label the parts of a flower.
Label: sepal, petal, ovary, ovules, anther, filament, stamen, stigma, style, pistil
Draw and label the frond of a fern.
What 5 things are necessary for photosynthesis to occur?
Carbon Dioxide (CO2) + Water (H2O) + Sun = Glucose (C6H12O6) + Oxygen (O2)
What resources do plants compete for in a jungle? What about a bog?
Jungle: Nutrients, sunlight, space, water
Bog: Nutrients, space, water
How has the stomata of desert plants adapted?
Stomata of desert plants close during the day and open at night
- Collect and store CO2 at night, then perform photosynthesis during the day when temp is hot
- Conserves water!
Compare and contrast monocots vs. dicots.
Monocots:
means “one cotyledon”
only have one cotyledon (embryonic leaf) in seeds.
Usually 3 floral parts (or multiples of 3)
Parallel leaf venation.
Dicots:
means “two cotyledons”
have two cotyledons in seeds.
Usually 4 or 5 floral parts (or multiples of these).
Netlike leaf venation.
What does a stomata do?
Opens and closes to let in carbon dioxide that helps the plant do photosynthesis.
Draw and label the leaf of a plant.
What phylum do ferns belong to?
Pteridophyte
Draw a fire triangle and explain why each part of the triangle is important to make a fire.
Spark - heat that sparks a flame
Oxygen - the gas that causes explosions of more fire
Fuel - the substance that the fire consumes to keep burning
What are the five ways that seeds can be dispersed? Be able to explain one example for each way.
1) Wind - dandelion seeds
2) Water - coconut/bean pod
3) Animal - strawberry in squirrel poop
4) Human - stuck to socks
5) Bursting - explosive
Draw and label the root of a plant.
What is the difference between a low and high intensity fire and how can we prevent high intensity fires?
Prevent: Can control the spark and fuel!
What ways can plants be pollinated?
1) Wind (grasses)
2) Insect (bees, flies)
3) Bird (hummingbird)
4) Mammal (bat)
