Chapter 20, Problem 12A

Summary Introduction

To analyze:

The structure of aseptate hyphae that involve in rapid growth.

Introduction:

The life cycle of multicellular fungi three stages; spores falling, hyphae developing, and finally mycelium forming. The creation and release of spores are done by the gills located under the mushroom cap. These spores are either single cell male or female attached together to form hyphae.

Explanation of Solution

In many fungi, hyphae are divided into cells by cross-walls called septa. The septa has large pores that allow the flow of nutrients, cytoplasm and organelles between cells. In some fungi, the septa is absent. The hyphae without septa are called aseptate hyphae. The cytoplasm containing thousands of nuclei, flows freely throughout the hyphae. Nutrients and other materials flow very quickly through aseptate hyphae.

Conclusion

Thus, aseptate hyphae do not have cell wall in individual cells.
