Chloroplast and mitochondria. Because both organelles are roughly the same size and shape as bacteria, have their own double layer membrane, and mitochondria have dna, that they were engulfed by early cells and are now organelles.
Answer:
a. commensalism is the correct answer.
Explanation:
By growing on the trunk or branch of a tree, a lichen gains height and exposure to sunlight for photosynthesis. The tree is not harmed by the lichen but does not benefit either. The relationship between the lichen and the tree is commensalism.
Commensalism is a relationship between two organisms where one organism gets benefits from other organisms without causing any harm or any damage from the relation as it one side symbiotic relation.
In this, we can see lichen is getting benefits from the tree.
for example, lichen is getting following benefits from the tree such as ( a lichen gains height and exposure to sunlight for photosynthesis.) and they are causing any harm to tree neither any benefits so this is a one-side symbiotic relation and thus the relationship is an example of commensalism.
<em>ATP stands for denosine tri phosphate ..
<u>formation:
</u>it is formed in the respiration ..also 36 molecules of ATP are formed during break down of 1 glucose molecule ..
<u>function:
</u>its function is to provide energy ,,
<u>how it provides energy:
</u>when one phosphate molecule separate ATP is converted into ADP and energy is released..
and when one phosphate is separated from ADP AMP is formed and energy is released ..</em>
Abiotic is the non living organisms and biotic is the living organisms.
