Study Notes
Plant Characteristics
- Eukaryotic cells with cell walls
- Make their own energy through photosynthesis
Plant Requirements
- Sunlight
- Water
- CO2
- Oxygen
- Nutrients
Types of Plants
- Seedless Nonvascular Plants (Bryophytes):
- Lack tissue to move water and sap
- Small, short plants that mostly live in moist environments
- Examples: mosses, liverworts, hornworts
- Vascular Plants (3 Subdivisions):
- Seedless Vascular Plants (Ferns, Horsetails, Clubmosses):
- Sperm travels in water to reach egg
- Seed Bearing Vascular Plants:
- Gymnosperms (Conifers, Cycads, Ginkgos):
- Male cones release pollen in the spring
- Female cones release sticky fluid to capture pollen
- Pollen burrows into female cone's ovule to fertilize egg
- Angiosperms (Flowering Plants, Grasses, Deciduous Trees):
- Monocotyledons (seeds with 1 leaf when sprouting)
- Dicotyledons (seeds with 2 leaves when sprouting)
- Gymnosperms (Conifers, Cycads, Ginkgos):
- Seedless Vascular Plants (Ferns, Horsetails, Clubmosses):
Gymnosperm Reproduction
- Male cones usually found at the highest parts of the tree
- Male cones have pollen that is carried by wind to female cones
- Female cones usually found lower on the tree than male cones
- Female cones open to take in pollen, then close tightly for germination
- Female cones open again to release the seeds
Flowering Plants
- Monocot Characteristics:
- Single Cotyledon
- Leaves with parallel veins
- Flower parts in multiples of three
- Vascular tissue throughout the stem
- Fiberous root system
- Examples: corn, bamboo, sugar cane, and grass
- Dicot Characteristics:
- Two Cotyledons
- Leaves with branched veins
- Flower parts in multiples of four or five
- Vascular tissue in a ring in the stem
- Tap root systems
- Examples: most trees, roses, daisies
Fruits
- In botany, a fruit is the seed-bearing structure in flowering plants
- Formed from the ovary after flowering
- Means by which angiosperms disseminate seeds
- Edible fruits have propagated with human and animal movements
Epiphytes and Legumes
- Epiphytes:
- Plants that grow harmlessly upon another plant
- Derive moisture and nutrients from air, rain, and debris
- Differ from parasites in that they do not negatively affect the host
- Legumes:
- Plants that bear their fruit in pods
- Very healthy food due to low fat and high protein content
- High in fiber and other nutrients
Plant Parts
- Roots:
- System for absorbing dissolved nutrients and water
- Anchoring
- Stems:
- Structure used to support the body of the plant
- Store sugar
- Leaves:
- Main photosynthetic region of the plant
Plant Transport
- Xylem Tissue:
- Cells that make hollow tubes that are water-proof
- Allow water to rise in a plant through capillary action
- Phloem Tissue:
- Cells that form tubes that allow foods and minerals to move in the plant
Plant Growth
- Meristematic Tissue:
- Tissue that allows the plant to grow up, down, or out
- Apical Meristem:
- Meristematic tissue that allows growth at the tips of the root and the tips of the branch
- Vascular Cambium:
- Meristematic tissue in the outer layer of the stem/trunk that allows growth outward (thicker)
