Green plant phylogeny ANSWER: - green algae and land plants share a common ancestor - all green plants are photo autotrophic but not all photo autotrophic plants are green 2 major groups of green algae ANSWER: - chlorophytes: never made it to land - charophytes: sister group to all land pants - ancestral charophytes species gave rise to land plants - streptophytes have charophytes and land plants - land plants have multicellular haploid and diploid stages and diploid embryos(not foun...

Gymnosperms - Answer-(conifers) Seeds not enclosed in ripened ovary. Angiosperms - Answer-(Flowering plants) Seeds are enclosed in a ripened ovary/fruit. 7 characteristics of seed plants - Answer-1. Megaphyllous leaves (branched veins w/ leaf trace gaps) 2. Heterospory [advanced] (production of spores of two different sizes and sexes) 3. Eusporangiate 4. Xylem and phloem 5. Dominant and independent sporophyte 6. Gametophyte is dependent on the sporophyte for nutrition 7. Reproduce by see...

Angiosperms - Answer - ovules are covered by ovary - vascular plant w flowers - produce fruit - has seeds (innovative) - most diverse land plants - dominated habitats in cretaceous period Gymnosperm - Answer Ovules lack cover Relationship between Angiosperms/Animals - Answer - Coevolved (complex) - Animals assist with pollination/defense/disperal - Animals are rewarded with nect/fruit/shelter - Allows for development of niches/diversification Dating Ocean Core Strata - Answer -...

adventituous root - emerges from the stem right above the ground to help support plants in shallow soils allopatric speciation - occurs when subpopulations are separated by some physical barrier. The two subpopulations remain reproductively isolated (no gene flow) and, over time, diverge from each other Angiosperms - Vascular plants with fruit-covered seeds The fruit increases the protection and dispersal of seeds; the largest number of species of all plants. 1. Flower: a major innovation...

Part A Click on the table to see the data the researchers collected for each Mimulus species. Which variables are positively correlated with the volume of nectar production in this genus? Select all that apply. - -seeds per flower -visits per flower Correct: Species that make a larger volume of nectar also have a higher number of seeds per flower and a higher number of visits per flower. Part A In angiosperms, each pollen grain produces two sperm. What do these sperm do? - One fertilizes...
