Imagine you are a botanist. Below are characteristics of a never-before described plant species recently identified as part of the ‘All Taxa Biodiversity Inventory’ (ATBI).Organism 1Field Notes: Specimen collected from rocks on bank of streams from the Adirondack Park (NY). Plant growth form is more ‘prone’ than upright (plant seems to have little support).Laboratory Analysis:Body: Consists of three regions: light brown anchoring tissue (base of plant); Green vegetative area (middle of plant); Brownish-green, stalk-like structure bearing capsule at end (top of plant).Size: 8 cm in lengthChromosomal Analysis: Bottom two thirds of plant is haploid (chromosome # 10), while top third of plant is haploid (chromosome # 20).Lignin test: NegativeCuticle: PresentLeaves: Absent, though they do possess green photosynthetic structures. Contains chlorophyll a, b; B-carotenes; xanthophylls.Roots: Absent, though they do possess anchoring (possibly absorptive) structures.Stem: Absent, though they do…

Of the 50,000 species introduced into the United States, half are plants. Describe two ways in which non-native plants might be brought to a new environment. How might we help prevent non-native plants from establishing in new areas and posing threats to native communities?

5. Coastal upwelling is important to California coastal ecology because ?   it brings necessary oxygen to the surface of the ocean, making it available to the photosynthetic organisms of the photic zone. it decreases the productivity in the areas it happens. it brings rich nutrients to the surface of the water, making them available to the photosynthetic organisms at the surface. it causes el Niño, which can be devastating to fisheries along the coast of California.
