Rahul studies a twig of a guava plant.
- What is the place on the twig where a leaf is attached called?
- What is the part of the twig between two such places called?
- A bud sits in the angle between a leaf and the twig. What is it called, and what can it become?
- What does the bud at the tip of the twig do?
Need a reminder? The key ideaShow
A node is where a leaf is attached. An internode is the stem between two nodes. An axillary bud is in the angle between a leaf and the stem. The terminal bud is at the tip. Underground stems (potato, ginger, turmeric, zaminkand, colocasia) store food and carry the plant through a bad season. Stem tendrils (cucumber) climb, thorns (Citrus) protect, and the flat stems of Opuntia make food. Runners, stolons and offsets spread the plant.
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 node.
Step 2. (b) The internode.
Step 3. (c) An axillary bud. It can grow into a branch or a flower.
Step 4. (d) The terminal bud makes the twig grow longer.
Answer: (a) node; (b) internode; (c) axillary bud, a branch or a flower; (d) it makes the twig longer.
