| Term | Definition |
|---|---|
| division of moss | bryophyte |
| nonvascular | no true transport system, moves materials by osmosis |
| do mosses have roots | no they have rhizomes |
| what is needed for reproduction | water |
| alternation of generation is | the life cycle of moss |
| life cycle of a plant switches from? | haploid to diploid forms |
| step 1 | gametophyte stage |
| spores develop into | moss plants you generally see |
| 1/2 the spores form male 1/2 spores form female these are called | gametophytes |
| step 1 of the gametophyte stage is | haploid |
| gametophytes make | gametes |
| archegonium | found in a female, flasked shaped, each make 1 large egg |
| antheridium | found in males, makes sperm, swims through ew or rain water |
| step #2 in gametophyte stage | fertilization |
| needs water to carry | sperm to egg |
| 2n diploid | sporophyte |
| capsule forms haploid(n) what | spores |
| step #3 in gametophyte stage | protonema |
| spores develop into the | protonema (baby moss) |
| protonema grows into the | gametophyte- which goes back to step #1 |
| archegonium | the female reproductive organ in ferns, mosses, |
| antheridium | A sperm-producing organ occurring in seedless plants, fungi, and algae. |
| capsule | A dry dehiscent fruit that develops from two or more united carpels. |
| spore | a walled, single- to many-celled, reproductive body of an organism, capable of giving rise to a new individual either directly or indirectly. |
| gametophyte | the sexual form of a plant in the alternation of generations. |
| sporophyte | spore producing plant generation. The dominant generation in pteridophytes and higher plants and alternates with the gametophyte generation. |
| zygote | fertilized egg |
| moss is vascular or non vascular | non vascular |
| how do you know moss is non vascular | it lacks true leaves and roots |
| how is water and materials transported in moss | through the rhizoids |
| what does moss have instead of roots | rhizoids |
| rhizomes | a rootlike subterranean stem, commonly horizontal in position |
| sori | a cluster of sporangia on the undersurface of certain fern leaves |
| seedless | lacking seeds |
| vascular | pertaining to, composed of, or provided with vessels or ducts that convey fluids, as blood, lymph, or sap. |
| frond | an often large, finely divided leaf, especially as applied to the ferns and certain palms. |
| how does the life cycle of moss compare to the life cycle of fern | both have spores also both go through fertilization |
| alternation of generation | life cycle |
| ancient ancestors of modern plants are thought to be the | green algea |
| what are the 4 divisions of natural plants | bryophyta,coniferophyta,anthocerophyta and pterophyta |
| give 4 adaptations land plants needed to develop | transport materials, prevention of water loss, support and reproduction |
| division | a major taxonomic group in the plant kingdom and fungi kingdom |
