Name: TA 14. What is the function of root hairs? 15. In what region of the root does a great deal of mitosis occur? 16. What is the function of the root cap? 17. How many steles do monocot roots have? 18. How many steles do dicot roots have? 19. What is the function of the endodermis? 20. From what layer of cells do new lateral roots arise? USEFUL PLANTS Tour the greenhouse and look for the plants that have been labeled because they are commonly used by humans for food, shelter, medicine, etc. 21. List five of these species (use common name). 22. (2pts) Choose one of the species and spend some time looking at it. Share an observation or a question about it:Explanation / Answer
14.
Function of root hair -
To collect water and minerals from the soil and take this solution up through the roots to the rest of the plant.
15.
The mitosis in roots occur in the region behind the root cap that is called Apical meristem.
16.
Function of root cap-
lt protects the growing tip in plants and secrate mucilage to reduce friction b/w root cap and soil to protect the
tissues of tip.
17.
The stele is the central part of the root.
monocot root has greater than 6 steles.
18.
dicot root has 2 to 6 steles.
19.
The endodermis is a single layer of cells that borders the cortex of a root.
The endodermis prevents water and other solutes dissolved in the water, from passing through this layer.
The endodermis does not allow gas bubbles to enter the xylem and helps prevent embolisms.
20.
Lateral root arises from primary root and in pericycle.
