Which type of reproduction is used by complex organisms?
Fragmentation is used by more complex organisms and occurs when a parent organism breaks into pieces or fragments, and then each piece develops into a new organism. An example is the starfish, which can develop from a single ray (arm) of the starfish. Starfish are unique that they can also reproduce sexually.
How do different organisms reproduce?
Organisms reproduce in two ways- asexually and sexually. Sexual reproduction involves the fusion of male and female gametes and can be seen in humans and many animals. Fission, budding, vegetative propagation, fragmentation are some different types of asexual reproduction.
Why do organisms want to reproduce?
Reproduction is important for the survival of all living things. Without a mechanism for reproduction, life would come to an end. Asexual reproduction refers to simple cell division that produces an exact duplicate of an organism.
Why do some organisms reproduce both sexually and asexually?
Organisms that reproduce sexually yield a smaller number of offspring, but the large amount of variation in their genes makes them less susceptible to disease. Many organisms can reproduce sexually as well as asexually. Sexual reproduction ensures a mixing of the gene pool of the species.
How do unicellular organisms reproduce?
Most unicellular organisms, and a few multicellular organisms, use cell division to reproduce, in a process called asexual reproduction. In one organism produces one or more new organisms that are identical to itself and that live independently of it.
How do organisms reproduce solutions?
(d) Multiple fission Organisms divide into many daughter cells simultaneously, e.g. Plasmodium. Answer: (d) Anther is the male reproductive part in plants….There are three main methods of contraception :
- Barrier methods,
- Chemical methods, and.
- Surgical methods.
Why do organisms reproduce Brainly?
Answer: Organisms reproduce to continue the chain of life, to pass on its genes which are acquired over millennia. Explanation: Reproduction is essentially a process by which individuals produce new individuals of the same kind.
How does reproduction take place in an organism?
Reproduction involves creation of a DNA copy and additional cellular apparatusby the cell involved in the process. Various organisms use different modes of reproduction depending on their bodydesign. In fission, many bacteria and protozoa simply divide into two or more daughtercells.
How are reproduction strategies used in multicellular organisms?
Multi-cellular organisms, therefore, need to use more complex ways of reproduction. A basic strategy used in multi-cellular organisms is that different cell types perform different specialised functions. Following this general pattern, reproduction in such organisms is also the function of a specific cell type.
How are organisms able to reproduce through spores?
Following are the ways through which an organism will be benefited if it reproduces through spores: Number of spores produced in one sporangium would be large. In order to avoid competition at one place, spores can be distributed to faraway places with the help of air.
Why is sexual reproduction a disadvantage for an organism?
This is a disadvantage because it inhibits the further evolution of the organism. (ii) In sexual reproduction the offspring, although similar to their parents, are not identical to them or to one another. This is because the offspring receive some genes from the mother and some from the father.
