Observe and Label this drawing of an onion root tip.
Label the following: root tip, root cap and the meristematic region.
1. What is the role of the root tip:
2. What is the role of the root cap:
3. Explain what a meristem region is:
4. What is the purpose of the plant roots:
5. Why would you be looking for mitotic cells in this region:
Homework Answers
Ans.1-The role of the root tip: The cells of root tip are actively dividing to form new cells.
Ans.2-The role of the root cap: Root cap contains cells that cover and protects underlying growth regions as the root pushed through the soil.
Ans.3- Meristem region: The region of cell division (meristem) where cells are actively dividing but not increasing significantly in size.
Ans.4- The purpose of plant roots:
(a) Absorption of water and nutrients from soil.
(b) Conduction of absorbed water and nutrients to stem.
(c) Storage of food.
(d) Anchoring of plant and soil binding.
Ans.5- Onion root tip are used to study the different stages of cell division, as root tip contains highly dividing cells.
