Charophyte chloroplasts contain chlorophyll a and b Charophyte plant cell walls contain plasmodesmata to allow transfer between cells within multicellular organisms Charophytes do not exhibit growth throughout the entire plant body Charophytes are multicellular organisms that lack vascular tissue.

The haploid form can be multicellular; the diploid form is unicellular The haploid form is unicellular; the diploid form can be multicellular Both the haploid and diploid forms can be multicellular Neither the haploid nor the diploid forms can be multicellular.Question #1. Briefly discuss and compare the plant habit and reproductive structures of the representative species of seedless vascular plants (Psilotum sp., Lycopodium sp., Equisetum sp., Selaginella sp., Adiantum sp., Ophioglossum sp., Angiopteris sp.)Seeds and pollen grains are key adaptations for life on land. These adaptations relate to reproductive success and survival advantages. The following questions require you to explain some of these adaptations. A. Contrast sperm delivery in seedless plants with sperm delivery in seed plants. (5-6 sentence) B. Discuss at least one feature of seed plants that contributed to their success on land in contrast with seedless plants. (2-3 sentences) C. Flowering plants (Magnoliophyta) are the most successful of all plant groups in terms of their species diversity and ubiquity across habitat types. Climate warming is causing shifts in the timing of life history events for many species. Discuss how climate warming may influence reproductive strategies employed by flowering plants. (2-3 sentence)
