What is the ploidy of hyphae?
What are the two possible ploidy levels of these hyphae? they are crosswalks; haploid and diploid. What type of cell division results in the production of spores by conidiophores? mitosis. Ascospores are produced inside of what structures?
What is the ploidy level of the spores produced in the Sporangium?
diploid (2n)
The sporophyte is a diploid (2n) spore-producing plant.
What is distinguishing feature of Septate hyphae?
Septate hyphae have dividers between the cells, called septa (singular septum). The septa have openings called pores between the cells, to allow the flow of cytoplasm and nutrients throughout the mycelium.
What are Septate hyphae quizlet?
Septate hyphae are divided into individual sections that keeps organelles in each section but allows cytoplasm to flow freely through the hypha. Coenocytic hyphae are one continuous mass of hyphae and organelles that has no separation.
Are hyphae made up haploid or diploid cells?
haploid
The spores divide and grow into mycelium which is a white network of threadlike structures called hyphae. Hyphae are root-‐like threads composed of haploid (haploid means they have only ½ of the normal number of chromosomes).
Are fungi Haplontic?
Most fungi have haplontic life cycle but some species of the Blastocladiomycota show typical alternation of generations between haploid gametophyte and diploid sporophyte. Slime molds (myxomycetes) and water molds (oomycetes) are distantly related to the true fungi (eumycetes).
What is the ploidy of the spore?
The spores produced in the sporangium are haploid. Sporangia are structures that develop on sporophytes, so they are diploid.
What is the ploidy of rhizoids?
The rhizoids are a part of the main plant body hence the haploid structure. The seta and capsule belong to the sporophytic generation, so the ploidy level is diploid(2n). Therefore, the answer is n, 2n, 2n.
What is the ploidy level of the Zygospores?
4) 2n, 2n, n, n, 2n. Dear Student, Option (1) is the correct answer. Zygospores are formed by the fusion of haploid cells, therefore, they have diploid reproductive life cycle.
Is the Basidium haploid or diploid?
In the gills of the fruiting body, some cells undergo fusion of these two nuclei. These now diploid cells are the basidia. The diploid phase is very brief. Soon after fusion, meiosis takes place, resulting in four haploid nuclei.
What is the difference between septate and non septate hyphae?
Hyphae that have walls between the cells are called septate hyphae; hyphae that lack walls and cell membranes between the cells are called nonseptate or coenocytic hyphae), As hyphae continue to grow, they form a tangled network called a mycelium.
What is the difference between septate and Aseptate hyphae?
The key difference between septate and aseptate hyphae is that septate hyphae have septa or cross walls that divide hyphae into distinct cells while aseptate hyphae lack septa. Hyphae are long filament or thread-like structures of fungi. Hyphae represent the vegetative structure of fungi.
What are long septate hyphae with 45 degree branching?
Long, septate hyphae, with 45-degree branching points, invade blood vessels and permeate alveolar septa.

What is a non septate hyphae?
Non-septate hyphae are the result of the nucleus repeatedly dividing but not the cytoplasm. This can result in many nuclei in the cytoplasm along with other organelles such as ribosomes, endoplasmic reticulum, and Golgi apparatus.
Do hyphae have a septum at the tip?
When hyphae grow at their tips, the septum does not form right away. As the cell matures, the wall grows out into the cytoplasm, eventually spanning the width of the hyphae. These types of hyphae are also called aseptate or coenocytic.
What is the function of septa in hyphae?
This is particularly important for newly formed cells at the hyphal tip. * Apart from simply compartmentalizing cytoplasm in different cells on the hyphae, septa also plays an important role of preventing the flow of nutrients and some organelles when some of the cells in the hyphae die.
