Plant Exam Review
seeds, roots, stems, leaves, reproduction and transpiration
| Question | Answer |
|---|---|
| cell wall | only in plants; gives protection, support, and shape to a plant |
| dormant | living but not actively growing; will grow if placed in the right environment |
| dead | no longer living; it did meet the 8 characteristics of life at some point |
| xylem | the system in plants that transports water |
| stomates | small holes in the underside of a leaf that regulate gas exchange and release of water vapor |
| guard cells | cells that control the opening and closing of stomates |
| germination | early growth stage of an embryo plant in a seed |
| order of growth of a plant | root, stem, leaves |
| cotyledon | primary source of energy for a seedling while underground |
| reproduction | main purpose of a flower |
| anther | part of a flower that produces pollen |
| pollen tube | a tube grown by the pollen grain down from the stigma that delivers sperm to the ovary |
| 3 main parts of a seed | seed coat, cotyledon, embryo |
| chloroplasts | use sunlight to create food during photosynthesis |
| monocot | has one cotyledon |
| dicot | has two cotyledons |
| 4 methods of seed dispersal | water, wind, animals, ejection |
| root | anchor plant in place, absorb water and nutrients |
| stem | provides support to the plant |
| leaf | carries out photosynthesis |
| hypothesis | an "if..then" statement |
| title | The effect of the IV on the DV |
| tropism | reaction of a plant to a stimulus |
| phototropism | a plant's growth towards light |
| carbon dioxide and water | the "raw materials" of photosynthesis; what a plant takes in |
| sugar and oxygen | the products of photosynthesis |
| chlorophyll | the pigment that makes a leaf appear green |
| the sun | energy that powers photosynthesis |
| gymnosperm | a plant that produces "naked" seeds--without a protective covering; reproductive parts are cones |
| angiosperm | a plant that produces flowers and fruit (seeds are enclosed in a protective covering) |
| fruit | a protective covering surrounding a seed or seeds that ensures their survival |
| pollination | when pollen lands on the sticky stigma |
| root hairs | increase the surface area of roots; absorb water and nutrients |
