Humans use sexual reproduction through the penis and vagina.
No, planaria do not do photosynthesis. They are free-living flatworms that are primarily carnivorous, feeding on small organisms in their environment. They rely on external sources of food for their energy needs.

Planaria are hermaphrodites, possessing both testicles and ovaries. Thus, one of their gametes will combine with the gamete of another planarian. This type of gamete fusion is sexual reproduction because it involves the formation and fusion of gametes. In asexual reproduction, the planarian detaches its tail end and each half regrows the lost parts by regeneration, allowing neoblasts (adult stem cells) to divide and differentiate. However, several problems can occur with this, so this does not happen often. Instead, in sexual reproduction, each planarian transports its excretion to the other planarian, giving and receiving sperm. Eggs develop inside the body and are shed in capsules. Weeks later, the eggs hatch and grow into adults. Sexual reproduction is desirable because it enhances the survival of the species by increasing the level of genetic diversity.
Binary fission is the process in which one can divide as a form of reproduction. Planeria are known for their binary fission which involves regenerating their bodies from parts that had been cut off. They are known to become two separate planeria after being severed in half, under the right conditions, and can even become double-headed if cut correctly.

Most of the terrestrial snails are hermaphrodites having the capability of producing both the ova and spermatozoa. The type of reproduction is therefore sexual.
