Bis 132 test 3 Symbiotic relationships involving plants  Ex. Acacia tree and acacia ants o Mutualistic o Tree provides shelter and food for ants o Ants defend tree against herbivores and other plants  Ex. Many species of plants have a symbiotic relationships with wasps o Mutualistic o Damage to the leaves by herbivores releases chemicals into the air which attract wasps o Wasps kill herbivores and lay eggs in them Ethylene C H 2 4  Gas  Produced by many plants  Plant hormone o Signals for fruit ripening  Ripening can lead to spoilage of fruits meant for food Genetic engineering: direct manipulation of genome using biotechnology  Creates transgenic organisms  Introduced antisense copy of the gene that synthesis ethylene  Transcribed into antisense mRNA, binds to normal mRNA, prevents translation o No ethylene production o Fruits will not ripen unless sprayed with ethylene New chapter Animal traits  Heterotrophs  Multicellular  No cell walls  Active movement  Sexual reproduction  Complex embryonic development  Tissues Body symmetry  Radial symmetry: any line through the middle creates symmetric halves  Bilateral symmetry: only one plane can create symmetry o Anterior:head o Posterior: tail o Dorsal:back o Ventral: fronts o o Body Cavity  Many animals are tues  Hollow in middle, two open ends  3 layers of cells o Ectoderm: exterior layer  Skin, nervous system o Mesoderm: Middle layer  Skeleton and muscles o Endoderm: interior layer  Intestines  3 possible body plans o Acoelomate: no coelom o Pseudocoelomate: cavity between mesoderm and endoderm o Coelomate: has coelom—body cavity within mesoderm o Protostones: during development, the indentation( blastopore) will eventually beome mouth o Deuterostomes: blastopore becomes anus o Colonial flagellate Hypothesis  Proposed explanation for the evolution of animals from protest  Some protest form colonies o Not true multicellularity (only happens if conditions are right) because no programmed development t multicellularity  Hypothesis: colonial protists evolved a program for multicellularity  Evidence: many sponges resemble colonial protists and DNA sequencing shows animal (sponges) most closely related to protists Parazoa: animals without specialized tissues  Specialized cells  Ex. Porifera (sponges) o Mostly marine( salt water) o Most lack symmetry o Sac body shape instead of a tube  Water enters through pores, exits through osculum o Specialized cells  Ex. Choanocytes:  Cels with flagella  Inside of sponge  Propel water through  Capture food particles o Body is strengthened by secreted proteins/ minerals o No nervous system  Individual pores can close in response to stimuli o Sexual and asexual reproduction Eumetazoa: animals with specialized tissue  Includes all further groups
