Why do plant cells need these two (2) organelles while animal cells do not?

Plant cells need Chlorophyll and a Cell wall.

Cell Wall: Plant cells are actively involved in water transportation, and thus plant cell wall ensures that the cell does not burst due to over expansion as water flows in (internal turgor pressure). It helps to maintain the shape and osmolarity of the cells and acts as defense against pressure due to inflow of water. Other than that they need cell walls to protect them from pathogens

Chlorophyll: The leaves contain a pigment called chlorophyll, which colors the leaves green. Chlorophyll can make food the plant can use from carbon dioxide, water, nutrients, and energy from sunlight. This process is called photosynthesis.
