Stroma, in botany, refers to the colorless fluid surrounding the grana within the chloroplast. Within the stroma are grana, stacks of thylakoid, the sub-organelles, the daughter cells, where photosynthesis is commenced before the chemical changes are completed in the stroma.
Q4=D. Taxonomy
Q5=C. Dichotomous Key
Taxonomy is the science of naming, describing and classifying organisms and includes all plants, animals and microorganisms of the world.
A dichotomous key is a tool created by scientists to help scientists and laypeople identify objects and organisms.
General Characteristics
Unicellular, absorptive-heterotrophic, photoautotrophic, or chemoautotrophic prokaryotes.
Only one set of genes, usually in a single-stranded loop.
Lack sexual reproduction.
Several chemical types of cell walls.
Lack organelles such as centrioles, eukaryotic flagella, cilia, mitochondria, and chloroplasts.
Some bacteria have a unique type of rotating flagellum.
Photoautotrophic species have chlorophyll, but not chloroplasts (which are organelles that are separated form the surrounding cytoplasm by their own membranes).
