Four things happen in a garden. Name the meristem that is responsible for each.
- The tip of a bean root pushes further into the soil.
- A lawn grows back after the mower has passed over it.
- The trunk of a mango tree becomes wider year after year.
- A scrape on a branch is covered by a new layer of cork.
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. (a) The root gets longer at its tip: the apical meristem of the root.
Step 2. (b) Grass grows from the base of its blades: the intercalary meristem.
Step 3. (c) The trunk gets wider: the vascular cambium, a lateral meristem.
Step 4. (d) Cork forms under the bark: the cork cambium, the other lateral meristem.
Answer: (a) apical meristem; (b) intercalary meristem; (c) vascular cambium; (d) cork cambium.
