Chapter 35, Problem 4S
Summary Introduction
To determine:
The affect of undifferentiated vessel cells on the functioning of the mutant maize plant.
Introduction:
Vessel cells are the primary water conducting and transporting cells in the plants. Xylem tissues or the vessel cells are responsible for the transfer of water and nutrients from the roots to different parts of the plants.

A student collected samples of cells from a woody plant during the spring and produced the drawings below. Sample 1 was collected from the woody stem of the plant. Sample 2 was collected from the root tip of the plant. Cells in different steps of mitosis are labeled with letters A, B, C, D, and E in Sample A) Describe the role of mitosis in the growth of a plant. B) Explain why there are more cells observed in mitosis in the root tip than in the woody stem.
Cells in the stem of a seedling that is grown in the dark orient their microtubules horizontally. How would you expect this to affect the growth of the plant?
Since you're done with your study of plant tissues, you may now answer the questions about them
below.
1. How do meristems accomplish the production of new, mitotically healthy cells?
2. What is indeterminate growth in plants?
3. What is de-differentiation in plant cells?

The overall negative results are that some plants cannot germinate (grow from seed) and other adult or growing plants will die. Explain what is happening on the cell level, in regards to transport across the cell membrane, why seeds might not germinate, and why adult plants might die.arrow_forward(a) Describe the role of mitosis in the growth of a plant.

- The image represents a flower meristem viewed from above. At the time the image represents, the cells are undifferentiated, although their eventual fates are determined (e.g. carpels, etc.). The rectangles indicate the regions of the meristem where particular genes (A, B, and C) are expressed. Note that these genes are expressed all around the circumference of the meristem at the location indicated; in other words, gene A is active in all cells in the rings labeled sepal and petals.
