The Biosphere
What are the four main spheres of the Earth
Atmosphere, Hydrosphere, Geosphere, Biosphere
What is the difference between vascular and nonvascular plants?
Nonvascular: No tubes to transport water and resources
Spores
What is the main difference between a monocot and dicot
Monocots have one cotyledon while dicots have two.
What is a biome? What is an example
A large community of life with similar environmental and biological characteristics
This brings water and nutrients from the roots to the plant
Xylem
What are the two types of seed plants
Gymnosperms
Angiosperms
What are the two things leaves do?
use sunlight for photosynthesis to make food
Lets CO2 in and water vapour and oxygen out.
What are three reasons soil is important?
1/4 of life is found in the soil
Provides nutrients to plants
Filters water
Biosphere couldnt exist without it.
This carries food from the leaves to the plants:
Phloem
How do angiosperms feed themselves before photosynthesis begins
Through the food stored in the cotyledons
What are the three things roots do?
Absorb water and minerals from the soil
Anchor the plant in the soil
Store extra food that the plant makes during photosynthesis
What are the three types of soil?
Sand
Silt
Plants are these three things and have this one important thing:
Are eukaryotic
Are multicellular
Are autotrophs
Have cell walls
Explain how gymnosperms reproduce?
What is the cell that creates energy through photosynthesis
Chloroplast
What is soil made of?
Eroded rock particles
Water
Air
Organic Matter
What are the five things plants need?
Soil
Air
Water
Sun
Space
What is the male part of the plant
What are the female parts of the plant
What is the substance needed for flower reproduction?
Male part: Stamen (anthers)
Female Part: Pistil (Stigma, style) Ovary
Pollen is needed for flower reproduction
What are the three tropisms we learned about? What do they do?
Gravitropism- plant growth in response to gravity
Phototropism- plant growth in response to light
Thigmotropism- plant growth in response to touch
