WebMost fungi and algae employ a life-cycle strategy in which the multicellular “body” of the organism is haploid. During sexual reproduction, specialized haploid cells from two individuals join to form a diploid zygote.

WebOct 4, 2024 · The zygote contains the genetic material of both the sperm and the egg. Mitotic division by the zygote then leads to all the cells of that organism. During development, cell proliferation and division are followed by specialization with each cell following a pathway towards differentiation. WebMulticellular filamentous moulds. Moulds are made up of very fine threads (hyphae). Hyphae grow at the tip and divide repeatedly along their length creating long and branching chains. The hyphae keep growing and intertwining until they form a network of threads called a mycelium. Digestive enzymes are secreted from the hyphal tip. how are roundworms spread in dogsWebProkaryotes reproduce through a cell division process called binary fission. Like mitosis in eukaryotes, this process involves copying the chromosome and separating one cell into two. Binary fission is an asexual form of reproduction, meaning that it does not involve production of eggs and sperm or mixing of genetic material from two individuals. how many miles is 19 000 meters
