Pollen cells are plant male gametes. On the other hand, algae cells autotrophic protists.
- Pollen cells and algae cells have DIFFERENT FUNCTION and DIFFERENT SHAPE.
- Algae are autotrophic microorganisms that synthesize their own food
- Algae belong to the Protista kingdom. These microorganisms can be unicellular or multicellular.
- Algae cells have many different forms.
- Pollen cells represent plant male gametes.
- During fertilization, pollen cells fuse with the egg cell to form a zygote.
- Pollen cells have many different forms (generally spherical).

Transfer of energy from one living to another in a food chain is called pyramid energy.
So simply we can energy pyramid shows how much energy passes from one living to another in a food chain.
Food chain always begins with autotrophs i.e. green nature (plants). Which becomes producers.
There are different types of organisms based on food habits and their environment.
It’s cell wall and chloroplast. We don’t need chloroplast because we don’t make our own food.
Answer:
D. Alternative splicing is the mechanism that produce complexity in the genes by splicing some of the protein coding part (exons) of a genes
Explanation:
There are certain splicing enhancers sites present in Exons which facilitiates the binding of RNA binding protein specifically SR protein family rich in Serine and Arginine residues. This SR protein will help in splicing of exons.
The significance of this type of mechanism is the ability of a cell to produce an isoform of protein which have retain their function.
This mechanism also help is diversity or in short in evolution.
Energy is lost at each trophic level.
