The organelles that are present in plant cells but not animal cells are:
- Cell wall
- Chloroplast
- Large, central vacuole
The primary function of carbohydrates in cells is to provide energy.
The organelle responsible for the synthesis of proteins in a cell is the Ribosome.
The organelle known as the "powerhouse" of the cell and produces ATP is the Mitochondrion.
The function of the cell membrane is to control the movement of substances in and out of the cell.

To determine which organelles are present in plant cells but not animal cells, we need to compare the characteristics of the organelles found in each cell type.
1. Cell Wall: The cell wall is a rigid layer that provides shape, support, and protection to plant cells. It is composed of cellulose and is not present in animal cells. Therefore, the cell wall is present in plant cells but not animal cells.
2. Mitochondria: Mitochondria are responsible for supplying energy to the cell through cellular respiration. Both plant and animal cells contain mitochondria, so this organelle is present in both.
3. Chloroplast: Chloroplasts are organelles responsible for photosynthesis, which is the process by which plants convert sunlight into energy. Chloroplasts contain chlorophyll and are only found in plant cells, making them not present in animal cells.
4. Large, Central Vacuole: Plant cells typically have a large, central vacuole that stores water, nutrients, and waste products. Animal cells, on the other hand, have multiple small vacuoles or no vacuoles at all. Therefore, the large, central vacuole is present in plant cells but not animal cells.
In summary, the organelles present in plant cells but not animal cells are the cell wall, chloroplasts, and the large, central vacuole.
Answer:
- Cell wall
- Chloroplast
- Large, central vacuole
