Three organelles (cell parts) found in plant cells, but not animal cells?

1. The Cell Wall.

Plants have a cell wall in order to maintain rigidity and stability. Animal cells do not have a cell wall because they have a different structure, which makes them more flexible and able to move around easier.

2. Chloroplasts

Since plants cannot move, they get their energy from the sun. This energy is made inside of the chloroplasts. Animal cells don't have chloroplasts because their energy comes from other organisms.

3. Central Vacuole

The central vacuole provides structure and holds materials and wastes, and also decomposes those wastes. Animal cells don't have a central vacuole because they have lysosomes and normal vacuoles that do the same function.

An ecosystem is in a certain area and includes living and non living plus there is weather conditions and a biome is a large amount of area with similar climate.so ecosystem is based on weather and biome is based on the average climate
