There's no need for evidence to prove that human blood is not made of plant cells. It's a fundamental biological fact. Here's why:

* Different Cell Types: Human blood is composed of various specialized cells, including red blood cells, white blood cells, and platelets. These cells are fundamentally different from plant cells in structure and function.

* Organelles: Plant cells have unique organelles like chloroplasts (for photosynthesis) and cell walls, which are absent in animal cells, including those in blood.

* Evolutionary History: Animals and plants diverged on the evolutionary tree billions of years ago, leading to distinct cell types and structures.

So, instead of looking for evidence, it's more accurate to understand the basic biological differences between animal and plant cells to understand why human blood is not made of plant cells.
