4.9B **Biology Only** - Tissue Culture Flashcards
What is tissue culture?
Tissue culture is a method of culturing living tissue, making it grow outside the organism within a growth medium.
What is a primary use of tissue culture in plants?
It is used to produce an entire field of identical cloned crops using just a small cutting.
Can tissue culture be used for animal and human tissues?
Yes, tissue culture can also be used to culture animal and human tissues outside of the body.
What is the first step in cloning a plant using tissue culture?
Take the plant that you would like to clone, preferably one with desirable characteristics.
What part of the plant is typically used for cloning?
A piece of tissue is removed from a fast-growing region of the plant, such as the root or shoot tip.
What technique is essential during the tissue culture process?
Aseptic technique is essential to maintain sterile conditions.
What is placed on the growth medium during tissue culture?
The tissue is placed on a special growth medium containing hormones and nutrients.
What happens after the tissue develops in tissue culture?
Once developed enough, the tissue can be transferred to compost for further growth.
What is a benefit of tissue culture?
It produces lots of offspring with a specific desirable feature.
What is a risk associated with tissue culture?
The gene pool is reduced through producing clones, making the population less likely to survive if a disease arises.
How can tissue culture affect crop yields?
Increasing the number of crops resistant to bad weather can increase crop yields.
What is a survival issue with clones produced through tissue culture?
Clones have a low survival rate and tend to have some genetic problems.
How can tissue culture help endangered species?
It can help extremely endangered species or even bring back species that have become extinct.
What ethical concern may arise from tissue culture?
It may lead to human cloning.
