flowering plants
| Term | Definition |
|---|---|
| division of a flowering plant | angiosperm |
| common characteristics of a flower plant | stem roots leaves flowers and seeds |
| 2 main groups of a flowering plant | monocot and dicot |
| # of cotyledons in monocots | one |
| # of cotyledons in dicots | two |
| veins in monocots | parallel |
| veins in dicots | netted |
| vascular tissue for stem and roots for monocots | separate |
| vascular tissue for stem and roots for dicots | together |
| stigma | receptive tip of a carpel |
| style | structural unit of a pistil |
| ovary | part of the reproductive organ |
| pistil | female organ of a flower that the stigma style and ovary make up |
| stamen | male fertilizing organ of a flower |
| anther | part of the stamen that contains the pollen |
| filament | thread like object that holds up the anther |
| sepal | each of the parts of the calyx of the flower |
| petal | each of the segments of the corolla of a flower |
| pollen | pollen grains that are produced by anthers |
| ovule | immature ovum |
| funiculus | a funicle |
| hilum | scar on a seed made by separation of its funicle |
| sepal | the opening of the coating in the ovule |
| petal | the outer coating of a seed |
| pollen | the fertilizing element of a flowering plant |
| cotyledons | undeveloped leaf of a seed plant |
| hypocotyl | part of a plant embryo directly under the cotyledons |
| epicotyl | part of the stem above the cotyledon |
| radicle | the primary root |
| what is the difference between fleshy and dry fruit | |
| endosperm | tissue within the seed of a flowering plant |
| what is the difference between fruits and vegetables | fruits contain seeds vegetables dont |
| perfect flower | flower having both stamens and carpels |
| imperfect flower | A flower that lacks either stamens or carpels |
| cone | A unisexual reproductive structure of gymnospermous plants such as conifers and cycads |
| pollen grain | microspore of a seed plant containing the male gametophyte |
| naked seed | another name for gymnosperm wich is a seed producing plant for example a conifer |
| what are the sporophytes of a conifer | the cone |
| what are the gametophytes of a conifer | pollen |
| what are the evolutionary adaptations that set conifers apart from fern | the shape the leaves |
| how does pollination occurs | anther touches the carrier the hair of the carrier makes the pollen stick and then the carrier takes the pollen over to another specimen to where a ripe stigma collects the pollen |
| what are some adaptations to increase pollination and fertilization | the amount of bees |
| what is double fertilization | The union in flowering plants of two sperm nuclei. One sperm nucleus unites with the egg to form the diploid zygote, from which the embryo develops, and the other unites with two polar nuclei to form the triploid, primary endosperm nucleus. |
| what are three types of plant tissue | ground tissue , dermal tissue and vascular tissue |
| what is the location of dermal tissue | the outer layering |
| what is the function of dermal tissue | gas exchange in leaves and stems also facilitates water and ion uptake in roots |
| what is the location of vascular tissue | through out the plant |
| what is the function of the vascular tissue | conducts water an solutes between organs and also provides mechanical support |
| what is the location of ground tissue | young part of the plant |
| what is the function of the ground tissue | food manufacture and storage |
| what are the steps in seed germination | 1. when a seed germinats, it absorbs water 2. the water causes the endosperm to swell, which cracks open the cotyleon 3. though the cracked seed coat, the young radicle begins to grow |
| what are the three main factors that affect seed germination | water,temperature and dormanation |
| what is the relationship between the size of the seed amount of stored food and depth of planting | larger- more stored food needs photosynthesis small- little stored food |
