A conservation biologist is utilizing micropropagation (tissue culture) to clone individuals of the endangered Venus flytrap (Dionaea muscipula). Excised tissue samples (explants) from a parent plant are sterilized and inoculated onto a nutrient agar medium inside a sterile culture vessel.
Identify the instrument used to excise the tissue samples, and describe how aseptic conditions are maintained during the inoculation of the explant onto the agar.
The agar growth medium is enriched with essential inorganic and organic nutrients. State the biochemical role of one specific named inorganic mineral ion and one named sugar that must be added to the medium to support tissue growth.
State three environmental parameters or physical precautions that must be strictly regulated in the incubation chamber to facilitate the successful regeneration of the cloned plantlets.
