Contributed by StemPy LabTry it on paper first. A hint, the key idea and the worked solution are here when you need them.
A gardener cuts a blade of grass to cm. The intercalary meristem at its base adds cm to the blade every day.
- How tall is the blade days after the cut?
- After how many days does the blade reach cm?
- Which meristem makes the new growth, and where does it lie?
Need a reminder? The key ideaShow
A tissue is a group of cells that work together. Meristematic tissue divides; permanent tissue has stopped dividing. Apical meristems lie at the tips of roots and shoots. Intercalary meristems lie at the base of leaves and internodes. The lateral meristems, the vascular cambium and the cork cambium, thicken the plant. Apical and intercalary meristems are primary; lateral ones are secondary.
The worked solution
Have you tried it?
Work it out on paper first. It is fine to get stuck or make a mistake: that is how we learn. When you are ready, go through the solution one step at a time, and check each step against your own.
Step 1. Height after days. New growth: cm. Height: cm.
Step 2. Days to cm. The blade must grow cm. At cm a day this takes days.
Step 3. The meristem. The intercalary meristem, at the base of the blade.
Answer: cm; days; the intercalary meristem at the base of the blade.
