Answer:
Hydra:
Reproduction by budding in Hydra.
Amoeba:
Reproduction by binary fission in Amoeba.
Hydra:
Budding means sexual reproduction in which a new organism develops from a bud in the parent.
Amoeba:
Binary fission is the type of asexual reproduction in which the parent divides to give rise to two daughter organisms.
Hydra:
In budding process, bud is simply an outgrowth of cells at one particular site.
Amoeba:
The parent replicates its genetic material and divides it equally between the two daughters in binary fission.
Hydra:
The bud or the newly formed organism remains attached to its parent until maturation.
Amoeba:
Both the cytoplasm and the nucleus of the parent divides into two.
 
        
             
        
        
        
The gene theory declares that all organisms contain coded information in DNA which dictates the form and function of organisms.
<h3>What does the gene theory state?</h3>
Gene theory is one of the major principles of biology that explains the inheritance of traits coded by gene from parents to offspring. 
This theory further explains that genes are located on chromosomes and consist of DNA, which stores them. 
Therefore, the gene theory declares that all organisms contain coded information in DNA which dictates the form and function of organisms.

Plants make their food in their leaves. And need sun for this process, so smaller and fewer leaves means less sun for photosynthesis, and it also means less food to nourish the plant.
