Lycophytes
________ and Pterophytes do not have seeds.
Vascular plants
________ include seven extant phyla grouped in three clades.
Sporophyte
________ consists of ribbed, jointed photosynthetic stems that arise from branching rhizomes with roots at nodes.
Gametophytes
________ consist of small, leaflike structures around a stemlike axis.
Fruits
________ in the flowering plants (angiosperms) add a layer of protection to seeds and attract animals that assist in seed dispersal, expanding the potential range of the species.
land plants
All ________ are haplodiplontic.
Cells
________ have a single large chloroplast.
Conspicuous sporophyte
________ and much smaller gametophyte are both photosynthetic.
Diploid spore mother cells
________ (sporocytes) undergo meiosis in sporangia.
Sporophyte
________ consists of evenly forking green stems without true leaves or roots.
Gametophyte
