Chpt 10 Plants
Plant Reproduction
| Question | Answer |
|---|---|
| Swollen base of pistil where ovules form | Ovary |
| Tissue in wheat seed where food is stored | Endosperm |
| Small, green, leaf-like parts that cover flower buds. | Sepals |
| Male reproductive organ of a flower | Stamen |
| Transfer of pollen grains from stamen to ovules | Pollination |
| Grows from a pollen grain to an ovule. | Pollen tube |
| Contains the reproductive organ of an angiosperm | Flower |
| The stalk part of the stamen | Filament |
| Female reproductive organ of a flower | Pisitl |
| Has a water-resistant covering and gametophyte parts that can produce sperm | Pollen grains |
| Protects the embryo | Seed coat |
| The part of the pistil between the ovary and stigma | Style |
| Where pollination takes place | Stigma |
| Where the eggs of gymnosperms and angiosperms are produced | Ovules |
| Where pollen grain forms | Anther |
| Underground stem of a fern | Rhizome |
| Leaf of a fern | Frond |
| Spore-producing structures on the underside of a fern leaf | Sori |
| Fertilized egg that has attached to the wall | Embryo |
| Plaint life-cycle stage that begins when an egg is fertilized by a sperm -- produces spores | Sporophyte |
| Plant life-cycle stage that begins when cells in reproductive organs undergo meiosis and produce haploid cells -- produces sex cells | Gametophytes |
| Contain half the number of chromosomes needed for a complete organism -- Gametes | Sex Cells |
| New diploid cell formed when a sperm fertilizes an egg | Zygote |
| Spores develop on the underside of the frond | Developing Spores |
| Process by which haploid cells are formed | Meiosis |
| The development of a seed into a new plant, begins when water is absorbed into the seed | Germination |
| When an organism produces offspring identical to the parent organism | Asexual Reproduction |
| When an organism produces many different-looking forms of the parents | Sexual Reproduction |
| Vascular plants that do not have flowers, generally have needlelike or scalelike leaves, and produce seeds that are not protected by fruit | Gymnoperms |
| Flowering vascular plant that produce fruits containing one or more seeds | Angiosperms |
| Ferns, produce spores in sori, the spores germinate into a prothaullus, the prothallus produces sex cells, the sex cells unite to form a zygote, the zygote develops into a sporophyte. | Life cycle of a fern |
| A structure within a seed that stores food for plants like beans and peanuts | Coryledon |
| Spores are produced by meiosis in sporophyte, spores land on soil and germinate into thin threadlike, green structures, small gametophytes grow and produce sex cells, the male sex cell swims to the female sex cells, they unite to form a zygote | Life cycle of a moss |
| To lure insects and other animals that help pollinate flowers. | Why are flowers often bright colored and smell. |
| Gravity, water, wind, animal, & some plants ejects seeds | Ways seeds disperse |
| No water available for germination | What conditions seeds remain dormant for long periods? |
