in ATP synthesis. Chloroplast chromosomes lack histones. Kinetochores Microtubules Motor proteins Actin filaments Kinetochores: Located in centromeres of condensed chromosomes; microtubule attachment sites necessary for chromosome positioning and movement. Telophase: Chromosomes disperse back to chromatin form, nuclear envelope reassembles, nucleoli reassemble. Basal bodies-Other structures support flagella. CAM plants uptake CO2 at night and change it into crassulacean acid that can be broken down during the day for sugars. According to the endosymbiotic theory, some organelles are believed to have evolved through a symbiotic relationship between eukaryotic and prokaryotic cells. The regulation of transpiration is an important homeostatic mechanism in plants.
Some xerophytes shed their leaves during the driest seasons and others can store water such as cacti. Plant, ring stand, floodlight, fan, spray bottle for mist, procedure. Prokaryotic cells lack membrane-bound organelles found in eukaryotes. Describe several adaptations that enable plants to reduce water loss from their leaves. We need to calculate the percentage of water. These plants can close their stomata during the day. However, prokaryotes must perform many of the same functions as eukaryotes.
