c. has spores contained in ascus
d. has spores contained in basidia
Answer is C. Truffles has spores contained in the ascus.
Explanation:
Fungi like yeasts, molds and mushrooms are eukaryotic organisms which acts as main decomposers in the environment. Black truffles are aromatic edible fungi which belong to the ascomycota phylum. They are expensive and normally seen in the southern Europe. The main feature of the ascomycota is the ascus, a sexual spore bearing cell containing spores called ascospores. Black truffles are round shaped with black-brown skin and has small pyramidal cusps. It contains tightly interwoven hyphae (long filament like structure) and numerous asci (spore bearing cells). Each ascus contains some spores called ascopores, which is specific to fungi classified as ascomycetes. Mushrooms belong to the basidiomycota phylum. They are also composed of hyphae and reproduce sexually via the formation of specialized cells called basidia which have spores called basidiospores.
Answer:
Explanation:
Not only is the biota important, but the abiotic factors in the ocean are also important because both groups work together. The abiotic factors in the ocean help the ocean to 'work'. For example, phytoplankton (autotrophs) need light, nutrients, CO2 (dissolved gases) to photosynthesize.
