Study Notes
Binomial Nomenclature
- Developed by Linnaeus
- Two-part naming system: genus and species
Cell Walls
- Plant cell walls are composed of cellulose
- Bacterial cell walls are composed of peptidoglycan
- Fungal cell walls are composed of chitin
Root Functions
- Anchorage to the ground
- Transportation of materials
- Mutualism with microorganisms
Xylem and Phloem
- Xylem carries water
- Phloem carries sugars and carbohydrates
Cuticle
- Waxy substance found on leaves
- Makes leaves waterproof or hydrophobic
Plant Reproduction
- Pistil is the female reproductive organ of a flower
- Stamen is the male reproductive organ of a flower
- Plants produce scents to attract pollinators
Theobromine
- Toxic substance found in cacao plants
- Can be lethal to dogs
Tree Age
- Determined by counting rings on the trunk
- One ring represents one year of growth
Seedless Plants
- Reproduce through spores found in sporangia
- Examples: ferns
Binomial Nomenclature
- Linnaeus developed the two-name naming system called binomial nomenclature
- It uses the genus and species to name an organism
Cell Walls
- Plant cell walls are made of cellulose, a complex sugar or polysaccharide
- Bacterial cell walls contain peptidoglycan
- Fungi cell walls are made of chitin
Roots
- Roots anchor plants to the ground
- Roots transport materials throughout the plant
- Roots form a mutualistic relationship with microorganisms
Xylem and Phloem
- Xylem carries water
- Phloem carries sugar or carbohydrates
Cuticle
- Cuticle is a waxy substance found on leaves
- Cuticle makes leaves waterproof and hydrophobic
Flower Reproduction
- Pistil is the female reproductive organ of a flower
- Stamen is the male reproductive organ of a flower
Theobromine
- Theobromine is toxic to dogs
- Theobromine is found in cacao plants
Tree Age
- Tree age can be determined by counting the rings on its trunk
- One ring corresponds to one year of growth
Plant Pollination
- Plants produce a smell to attract pollinators
Seedless Plant Reproduction
- Seedless plants reproduce via spores
- Spores are found in the sporangia of the sorus or sorii
- Ferns are an example of seedless plants
