[1] The term is sometimes used inaccurately to describe reproduction modes in hermaphroditic species that can reproduce by themselves because they contain reproductive organs of both sexes in a single individual’s body. Normal egg cells form after meiosis and are haploid‚ with half as many chromosomes as their mother’s body cells. Haploid individuals‚ however‚ are usually non-viable‚ and parthenogenetic offspring usually have the diploid chromosome number. Depending on the mechanism involved in restoring

Cell Fractionation * Cell Fractionation: takes cells apart and separates the major organelles and other subcellular structures from one another. * Tissue cells are the first one to be homogenate or broken apart. * Plasma membranes are broken up so that there internal contents spill out and mix together and this is called homogenate. * Homogenate is in spun in a higher rate of speed in a process called centrifugation. And that speed can vary that why it’s called differential

rhizome. Ferns can range many heights depending on their environment. Tropical ferns can grow very high while ferns in temperate areas can be rather small. Sporangium is generally found on the underside of fern leaves. Cells in the sporangia undergo meiosis and form haploid spores that are released into the air. Gymnosperms Gymnosperm‚ meaning naked seed includes some of the tallest and oldest plants in the world. It differs from lycopods‚ horsetails and ferns because they’re fully adapted to life

college work and classrooms typically don’t reflect on those in a high school. One assignment was a persuasive essay‚ and I chose stem cell research. Stem cell research was always a topic brought up in science classes when we would be covering mitosis and meiosis even though many of my teachers knew the basic facts about the subject. I wanted to finally shed some light on the subject and finally see if the argument was valid. Was stem cell research as gruesome as it is made out to be? The research
