Plant Vocabulary
Term | Definition |
---|---|
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 |
