No Mate? No Worries!

Early life on Earth consisted of single-celled organisms that reproduced by dividing into half or what is formally known as asexual reproduction. As life evolved and more complex and multi-cellular organisms were created, two sexes became distinguished- the male and the female, which were both required in the process of sexual reproduction. It is believed that nature promotes sexual reproduction since it provides an opportunity of recombination of genetic material in a given population.
There is evidence for sexual production in plants as well and distinct male and female plants do exist. Usually a female produces an egg which is then fertilized by a male gamete to give rise to an embryo, which grows into an adult organism. So, when we were busy considering ‘Dioecy’ (species have distinct male and female organisms) as one proof of our evolution, scientists have found that certain females can reproduce without the need of a male. Offspring produced in such a manner are often females a…

Animals that live on Sunlight!

We have long since known that plants and algae are capable of using sunlight to synthesize their own energy. They essentially create their own food, and that was, by far, the clear distinction that separated plants and animals. However, nature just blurred that distinction further! Scientists have found that there are some pretty incredible animals that have been doing what we thought was a skill exclusively gifted to plants - photosynthesis.
These unique animals dubbed, ‘photobionts’ are capable of surviving only with light and air. One such animal is the solar powered, sacoglossan mollusc or the sea slug. Now one would imagine that this must be some sort of symbiotic relationship being maintained between a photosynthetic plant and the slug. On the contrary, the sea slug steals the photosynthetic apparatus from the plant/algae it engulfs. It doesn’t just stop at that, it also retains the photosynthetic genes from its meal! And like all animals, the sea slug is not selfish, it also thi…
