Plant Vocabulary

TermDefinition
autotroph an organism that gets energy by producing its own food.
asexual reproduction reproduction involving 1 parent
nonvascular a plant that has no tubes ("veins") to transport water and nutrients
scientific name an organisms genus and species
heterotroph an organism that gets energy from other sources
dicot a flowering plant that has 2 cotyledons, branching veins in its leaves, scattered vascular bundles in the stem, and flower parts in 4's and 5's
xylem vascular tube that transports water up from the roots to the rest of the plant
vascular a plant that has tubes ("veins") to transport water and nutrients
monocot a flowering plant that has 1 cotyledon, parallel veins in its leaves, vascular bundles in a ring in the stem, and flower parts in 3's
sexual reproduction reproduction involving 2 parents
phloem vascular tube that transports food down from the leaves to the rest of the plant
anther plant reproductive structure (male) that produces pollen
stigma plant reproductive structure (female) that is sticky and catches pollen
filament plant reproductive structure (male) that supports the anther
pistil female plant reproductive structures
style plant reproductive structure (female) that supports the stigma and connects it to the ovary
stamen male plant reproductive structures
ovary plant reproductive structure (female) that is where egg cells are produced
ovule plant reproductive structure (female) that holds the fertilized egg (embryo)
embryo a tiny new plant
spore a plant cell that can create a whole new plant
germination early stage of plant growth where the roots start to grow down and the stem starts to grow up
fertilization when pollen goes from the stamen to the pistil and enters the ovule
dormant a period of time when a plant stops growing (goes to sleep) and waits until the conditions are right
seed production after fertilization, the ovule begins to grow and forms a fruit
plant development as leaves grow and start making food for the plant, it gets larger and develops its own reproductive structures
cotyledon a protective covering ("coat") for a seed
tropism a response by part of a plant towards or away from a stimulus
phototropism a plant's growth response to light
gravitropism a plant's growth response to gravity
thigmotropism a plant's growth response to touch
hydrotropism a plant's growth response to water
fungus a kingdom of organisms that cannot make their own food; instead they live in or on other organisms
photosynthesis a process in which plants use water, carbon dioxide, and energy to produce sugars and oxygen
respiration a process in which plants use oxygen and sugars to produce water, carbon dioxide, and energy
transpiration a process in which plants control water loss through their leaves
stomata small holes on the bottom of a leaf that let stuff in and out of the plant
guard cells cells that open and close the stomata
chloroplasts structures in the cells of plants where photosynthesis takes place
chlorophyll green material in plants that trap energy from the sun
tubers/bulbs underground stems that can grow into a whole new plant
runners special stems that grow above ground and allow plants to reproduce asexually
