| Part of a leaf that protects the plant | epidermis |
| tiny openings on the bottom of leaves | let air in and out of the plant |
| organs | leaves, stems, roots |
| product of photosynthesis | oxygen and sugar |
| water enters the plant | root hairs |
| woody stems | have the most xylem |
| xylem tissue | carries water mixture and minerals from the root to the rest of the plant |
| pollen | made in tissue at top of stamens |
| pollination | creates a new plant with characteristics from each parent plant |
| dicot | a seed with two areas of stored food |
| spores | are not made by fertilization |
| asexual reproduction | the offspring plant has the same genes as the parent |
| rate of plant growth | determined by the DNA and environment |
| tropism | plant stems bending toward the light |
| two types of asexual reproduction | runners and budding |
| plants need sunlight to make sugar for food | Why is there less sugar in a plant at nighttime? |
| Ways pollen can move | wind, water, insects, birds |
| pollen goes from the stamen to the pistil | First step of pollination |
| A tube forms down the pistil and the pollen fertilizes the egg | Second step in pollination |
| The egg grows and divides many times to form a seed | Third step in pollination |
