Chapter 4, Problem 2CT
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.

Students have asked these similar questions
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?
The plant wall allows for plant cells to swell under large internal pressure, what membrane lined passage allows for rapid movement of polar molecules between cells?
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?

- In the fluid mosaic model: plasma membrane proteins orient their hydrophilic sides toward the internal bilayer. phospholipids often flip-flop between the inner and outer layers. the mosaic refers to proteins attached to the underlying cytoskeleton. the fluid refers to the phospholipid bilayer. the mosaic refers to the symmetry of the internal membrane proteins and sterols.arrow_forwardWhy is the plant cell rigid, but a human cheek cell is misshapen and folded over on itself?arrow_forwardWhich 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_forward

The concentrations of some dissolved materials remain virtually constant in the cells of the seaweed.arrow_forwardWhy is cell wall called the outer fence of the plant cell?arrow_forwardConsider a plant that is exposed to extreme cold temperatures. Do the cells of this plant manipulate the composition of their membranes in response to this environmental stress?If not, explain why the plant does not manipulate membrane composition in response to this stress.If so, explain the specific changes that these cells would carry out in response to this environmental stress.arrow_forward

This type of transport usually applies to enzymes and hormones. Can you cite an Texample in plants where this form of transport is beneficial? How about in animals?arrow_forwardMost adjacent plant cells are connected by plasmodesmata, whereas only certain adjacent animal cells are connected through gap junctions. What might account for this difference?arrow_forward
- Secretory vesicles fuse with the cell membrane to release their contents to the outside of the cell. 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_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.
