Question
Chapter 4, Problem 3CT
Summary Introduction
To explain: A secondary cell wall forms on the inner side of the primary cell wall in plants instead of on the outer surface of it.
Concept introduction:
The plants are enclosed by cell wall secreted by extracellular matrix. It is the thin layer formed on the outer surface of the plasma membrane and allows the cell to enlarge during the growth. It is known as the primary cell wall. In some plants, such as woody plants, a secondary cell wall forms on the inner side of the primary cell wall. It is composed of lignin that is found in the xylem walls and fiber cells of woody tissues.

In plants, the cell wall forms as a young plant cell secretes polysaccharides onto the outer surface of its plasma membrane. Being thin and pliable, this primary wall allows the cell to enlarge and change shape. At maturity, cells in some plant tissues deposit material onto the primary wall’s inner surface. Why doesn’t this secondary wall form on the outer surface of the primary wall?
In farming communities, there is a concern that over irrigation can leech nutrients out of the soil, flood a farm area, and add salt to the soil in a process called salinization. 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.
What are the most abundant components of a plant cell walls? How do the components interact, and how are they arranged with respect to each other?

- Which statement about the cytoskeleton is incorrect? Microtubules are hollow tubes of protein that provide structural support. Plant cells lack a cytoskeleton because they have a rigid cell wall. Intermediate filaments are more permanent structures in cells compared to microfilaments and microtubules. Microfilaments are chains of proteins that resist stretching. Components of the cytoskeleton are often involved with movement of organelles within the cytoplasm.arrow_forwardLabel and show the loeatons of the following organelles on the dagram of a plant cell below: Cell wall, Plasma (cell) membrane, cytoplasm, mitochondria, chloroplast, nucleus, vacuole, endoplasmic reticulum, ribosomes, nuclear membrane, nucleolus, golgi apparatus 0 0 0 0arrow_forwardA cell that is missing this structure would not have a rigid structural support outside of its plasma membrane and would not be protected from exploding when placed in water.

In this process, the membrane of the secretory vesicle becomes part of the cell membrane because small pieces of the membrane are continually added to the cell membrane, one would expect the cell membrane to become larger and larger as secretion continues. The cell membrane stays the same size, however. Explain how this happens.arrow_forwardSecretory vesicles fuse with the cell membrane to release their contents to the outside of the cell.
