BIOL 121 Lecture Notes - Lecture 8: Red Blood Cell, Lumbricus Terrestris, Protist
Document Summary
If only one leaflet touches, electric signals travel throughout plant causing the entire leaf to fold. Sensory hairs in inside of leaf, when insect comes and touches those hairs, it will close shut: life reproduces itself. Reproduction production of new individual organisms (offspring) from living organism (parent or parents) (a component of that is mating. ) Replication the duplication of genetic material (a part of reproduction) (even non-living things can replicate ex) virus) Types of asexual reproduction (4: fission , one ind separates into 2 ind of equal size (binary fission) Examples: paramecium (ro), euglena, micrasterias (ro: multiple fission: one ind separates into several ind of equal size e. g. , protist plasmodium (causative agent of malaria) inside a red blood cell. Common earthworm lumbricus terrestris (ro) reports of fragmentation and regeneration not common (uses sexual reproduction). Breaking a common earthworm, not likely it will fragment and regenerate. Some species of annelid reproduce by asexual reproduction.
