|
Embryophytes or land plants |
Embryos of plants depend on maternal protection and resources for their development |
|
|
Nonvascular plants or bryophytes |
Group of plants that has no vascular tissues, true roots, true stems, or true leaves; has gametophytes that are dominant and sporophytes that are small and dependent on gametophytes for survival; includes liverworts, hornworts, and Moses |
|
|
Vascular seedless plants |
Group of plants that have vascular tissues, true roots and stems; you sportsters person; have sporophytes that are dominant and gametophytes that are small but independent from sporophyte; includes club mosses, ferns, and their realtors. |
|
|
Angiosperms or flowering plants |
Group of vascular seed plants that produce seeds in their seeds are enclosed within a fruit, which is a mature or ripened ovary. Angeion in Greek means vessel and sperm means seed |
|
|
Gymnosperms or conebearing plants |
Group of vascular seed plants that produce seeds and their seeds are not enclosed within a fruit; includes cycads, ginkgo, gnetophytes, and conifers |
|
|
Eutracheophytes or true vascular plants |
Land plants that have lignified tracheids to transport water and minerals; all vascular plants |
|
|
Polymers |
Complex and big molecules made up of many subunits called monomers |
|
|
Euphylls or true leaves |
Leaves with a branched vascular system and leaf gaps in the stem |
|
|
Cuticle |
Found on the surface of stems and leaves made up of cutin and wax, which makes plant surfaces waterproof and reflective |
|
|
Sporopollenin |
Major component of the outer walls of plant spores and pollen grains; it helps spores and pollen grains to prevent excess water loss and resist decomposition |
|
|
Sporangia |
Structure that produces spores |
|
|
Gametangia |
Structures that produce gametes or sex sells |
|
|
Gametophytes |
Adult plants produce gametes by mitosis in their gametangia |
|
|
Sporophytes |
Adult plants that produce spores by meiosis in their sporangia |
|
|
Haploid |
Having one set of chromosomes in the cell |
|
|
Diploid |
Having two sets of chromosomes in the cell |
|
|
Antheridia |
Male gametangia for producing haploid sperm |
|
|
Antheridia |
Male gametangia for producing haploid sperm |
|
|
Archegonia |
Female gametangia for producing haploid eggs |
|
|
Alternation of generations |
Unique lifecycles of plants; plants spend part of their lives as multicellular haploid gametophytes and part as multicellular diploid sporophytes |
|
|
Mycorrhizas |
Symbiotic relationships between fungi and plant roots or rhizoids; enhance plant tolerance to stresses and facilitate water and nutrient uptake |
