Plants

TermDefinition
Nonvascular Plants leaf-like and root-like structures; examples: moss, liverworts, and hornworts
Importance of Nonvascular Plants 1st to emerge in new environment; reduce soil erosion; food/nesting source; fuel source for humans
Vascular Plants Contain true stems, roots, and leaves; ability to grow large/tall; contain vascular tissue
Stem Function Support leaves and transport materials
Leaf Function Primary site of photosynthesis
Root Function Water absorption; food storage; anchor plant into ground
Vascular Tissue Xylem (carries water) & Phloem (carries food)
Xylem Moves water throughout plant
Phloem Moves food throughout plant
Seedless Vascular Plants True stems, roots, & leaves; vascular tissue, reproduce with spores; example: ferns
Gymnosperms True stems, roots, & Leaves; vascular tissue; naked seeds; primarily reproduce with cones
Angiosperms True stems, roots, & leaves; vascular tissue, produce fruits with seeds; flowers are reproductive structures
Male reproductive structures for angiosperms Stamen (consisting of filament, anther, and pollen)
Female reproductive structures for angiosperms Pistil (consisting of stigma, style, ovary, ovule or seeds)
Pollination The delivery of pollen to the sticky stigma
Fertilization The union of sperm and egg inside the ovary
Fruits Matured ovaries containing seeds
Stem Types Herbaceous (soft and flexible) and woody (nonflexible)
Germination The sprouting or growth of a seed
Tropism Plant response to an environmental stimuli
Phototropism Plant response to light; growing towards the light (positive) roots growing away from the light (negative)
Geotropism Plant response to gravity; roots growing with the downward pull of gravity (positive); stems and leaves growing upward against gravity (negative)
Photosynthesis Raw Materials Carbon Dioxide and Water
Photosynthesis Products Glucose and Oxygen
Cuticle Waxy covering on outside of leaf to assist in water retention
Stomata Opening on underside of leaf for gas (oxygen and carbon dioxide) exchange with environment
