Why do you think leaves have stomata on their underside only? Explain.

Alexandra [31]

The stomata must be open during the daylight hours to let oxygen and carbon dioxide pass through. While they are open, water vapor escapes into the atmosphere (transpiration). ... Transpiration is the loss of water through stomata, so, more stomata are found on the lower surface to prevent excessive loss of water.

In a lotus plant, stomata is found on the upper epidermis of the leaf.

Stomata are responsible for the exchange of gas with the surrounding atmosphere of the leaf. Their guard cells stay taut during the day to keep the stoma open.

Guard cells can only stay open if they are saturated with a certain quantity of water.

From this information we can infer that stomata are typically found on the lower epidermis to prevent water damage when it rains.

The rain would not only cover the openings, it would also ruin the osmotic balance of the guard cells causing inefficiency and damage to the cycle of gaseous exchange.

Natural selection probably selected against such plants giving rise to those with stomata on the underside.

On your first research mission you make an amazing discovery by finding a new species living in the hostile environment of the s

Tomtit [17]

The best classification for this new species is Animalia.

According to the six kingdom classification given by Carl Woese, all organisms are divided into 6 kingdoms.

1) Archaebacteria

2) Eubacteria

3) Protista

4) Fungi

5) Plantae

6) Animalia

As the newly discovered species is a multicellular (made up of more than one cell) organism.

Then it can only belong to Kingdom Fungi, Plantae and Animalia as the rest of the kingdoms like Archaebacteria, Eubacteria and Protista consist of unicellular organisms that are made up of only one type of cell.

Now this species is not autotrophic ( i.e. an organism that can get its own nutrition by the use of light, water, carbon dioxide, or other substances).

It means it is heterotrophic which means it can't get nutrition on its own.

Out of the Fungi, Plantae and Animalia , only fungi and Animalia kingdoms consist of heterotrophic organisms.

Now this species also does not contain chitin which is an important characteristics of Fungi.

So only option left is Animalia.

Hence, the best classification for this new species is Animalia.
