Complex organisms have highly differentiated tissues and organs and not a single cell of a tissue is able to produce another type of tissue. For example, a dog is a complex multicellular organism and if we cut dog into two parts, then the cells of one part are not able to produce cells of other bodyRead more
Complex organisms have highly differentiated tissues and organs and not a single cell of a tissue is able to produce another type of tissue. For example, a dog is a complex multicellular organism and if we cut dog into two parts, then the cells of one part are not able to produce cells of other body part to produce a complete dog but in case of hydra (simple organism), regeneration takes place because cells in the cut body part are able to produce cells of other body parts.
The spores are covered by thick wall that protects them from unfavorable conditions like lack of food, water or high temperature. But as the conditions become favorable these spores can grow to produce new plant. So, an organism will be benefited if it reproduces through spores.

Binary fission: It is the process of asexual reproduction, in which parent organism divides to form two new organisms. For eg. Amoeba-Amoeba reproduces by binary fission. Multiple fission: It is the process of asexual reproduction, in which parent organism divides to form many new organisms. For egRead more

Variation is beneficial to the species but not necessarily for the individual because sometimes variation in an individual may results in death of that individual but for species variation results in the existence of that species. For example, if there is a population of certain bacteria living in nRead more
Variation is beneficial to the species but not necessarily for the individual because sometimes variation in an individual may results in death of that individual but for species variation results in the existence of that species. For example, if there is a population of certain bacteria living in normal climatic conditions and the temperature increases due to global warming, then most of these bacteria will not be able to tolerate excessive heat and hence die. But some bacteria which had variations to resist heat would survive and grow further. So, we can say, variation is beneficial to species but not necessarily for the individual.
Importance of DNA copying in reproduction are as follows - (i) DNA copying is the basis of inheritance of traits from parents to offspring. (ii) During copying of DNA, sometimes slight variations occur which form the basis for evolution.

Can you think of reasons why more complex organisms cannot give rise to new individuals through regeneration?
