What are the different meristems? What can each do?
What will be an ideal response?
Apical meristem, found in buds, allows primary growth (growth in length) of stems, shoots, and roots. Lateral meristems, also called cambiums, allow secondary growth (growth in girth) of roots and stems. There are two types of lateral meristems, cork cambium, which forms the bark of trees, and vascular cambium, which adds secondary xylem and phloem.

Answer the following statements true (T) or false (F)
1. When Ron Evans generated transgenic mice in which the gene PPAR-delta was constitutively active (i.e., always expressed), he found that these mice showed a shift from fast glycolytic fibers to slow oxidative fibers. Based on this, faster sprint speeds in the transgenic mice would also be predicted. 2. The fact that a quarterback can throw a football at approximately 50 miles per hour means that the muscles powering this throw must also be shortening at 50 miles per hour. 3. Walking or running are more energetically expensive forms of locomotion than either swimming or flying. 4. The only chyme molecule that is absorbed in significant amounts by the stomach is water.
