In this activity related to plant biotechnology, learners use the tissue culture process to rapidly produce clones (genetic copies) of a particular plant (cauliflower, rose cuttings, African violet leaves, or carnation stems). This lab will help learners understand a procedure that is often used by scientists to propagate many plants of the same genetic background as well as to understand the importance of sterile techniques. Adult supervision recommended. Modifications for younger learners are included in a related PDF (see related resources). This resource also contains background information and questions with answers for learners.
