Plant cells have cell walls, constructed outside the cell membrane and composed of cellulose, hemicelluloses, and pectin, a cell membrane similar to that of the animal cell, a large central vacuole, a water-filled volume enclosed by a membrane known as the tonoplast, they contain plastids, the most notable being chloroplasts, which contain the green-colored pigment chlorophyll that converts the energy of sunlight into chemical energy, and then all the other organelles of the animal cell (mitochondria, endoplasmic reticulum, nucleus and nucleolus, golgi apparatus, etc.)

There should not be any changes in the gene pool.
In Hardy-Weinberg equilibrium, the gene pool should have a constant rate. The equilibrium can be achieved if there is no factor that favors one gene more than the others. Since the genes have the equal chance to survive and mating, the ratio of the gene pool should not change dramatically.
Ecosystems can be large and are made of biomes. Some examples of ecosystems are deserts and forests.
