WitrynaMost 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. The zygote immediately undergoes meiosis to form four haploid cells called spores ( Figure 7.2 b ). simple green lawn careWitrynaThe differences between the individuals in a species is called variation. Variation helps a species to survive, by causing individuals of a species to be genetically and physically different. Video Humans, dogs and goldfish are examples of species.
