Parenchyma, collenchyma, and sclerenchyma are the simple tissues with each consisting of one type of cell. Sclerenchyma cells are variably shaped and they will die once they are matured. They have thick cell wall which is made up of polymers like cellulose and lignin. These polymers will provide sturdiness to plant parts and help them resist stretching and compression.

Chapter 27, Problem 1SQ

Summary Introduction

Concept introduction: Parenchyma, collenchyma, and sclerenchyma are the simple tissues with each consisting of one type of cell. Sclerenchyma cells are variably shaped and they will die once they are matured. They have thick cell wall which is made up of polymers like cellulose and lignin. These polymers will provide sturdiness to plant parts and help them resist stretching and compression.

Expert Solution & Answer

Answer to Problem 1SQ

Correct answer: In plants, fibers are a type of sclerenchyma cell. Therefore, option b. is correct.

Explanation of Solution

Reasons for correct statement:

Fibers and sclereids are made up of sclerenchyma cells. Fibers are long, tapered sclerenchyma cells that occur in bundles and they will support and protect the vascular tissues. These cells die at the stage of maturity and their lignin reinforced walls will remain and support the plant.

Option b. is given as “sclerenchyma”. As the plant fibers are made up of sclerenchyma cells option b. is correct.

Reasons for the incorrect statements:

Option a. is given as “parenchyma”.

Parenchyma is made up of parenchyma cell which has a thin and flexible cell wall. It has specialized roles that varies with the location of the plant. Therefore, option a. is incorrect.

Option c. is given as “collenchyma”.

Collenchymas remains alive in mature tissues and its cells have sturdy, flexible walls that support fast-growing plant parts. Therefore, option c. is incorrect.

Option d. is given as “mesophyll”.

Mesophyll is a photosynthetic parenchyma that is filled with chloroplast. Therefore, option d. is incorrect.

Hence, options a., c., and d. are incorrect.

Conclusion

The fibers in plant cells are made up of parenchyma cell.

Alleles at the P locus control seed color. Plants which are pp have white seeds, white flowers and no pigment in vegetative parts. Plants which are P_ have black seeds, purple flowers and may have varying degrees of pigment on stems and leaves. Seed color can be assessed, visually, based on if the seed is white or not white A gene for mold resistance has been reported and we want to determine its inheritance and whether it is linked to P. For the purposes of this exercise, we will assume that resistance is controlled by a single locus M, and M_ plants are resistant and mm plants are susceptible. Resistance can be measured, under greenhouse conditions, 2 weeks after planting, by injecting each seedling with a spore suspension. After two weeks, the seedlings can be rated as resistant or susceptible, based on whether or not tissue is actively sporulating. For this exercise we will use seed and data from the F10 generation of a recombinant inbred population produced using single seed…
