Explanation:

1. Cell wall of a plant cell is made up of cellulose: This statement is correct. Cellulose is a complex carbohydrate and is the main component of the cell wall in plant cells. It provides structural support and protection to the cell.
2. The plant cells cannot divide by mitosis: This statement is incorrect. Plant cells, like animal cells, can divide by mitosis. Mitosis is a type of cell division that occurs in somatic cells and is responsible for growth, development, and tissue repair in both plant and animal cells.
3. A plant cell usually contains a large vacuole: This statement is correct. Plant cells typically contain a large central vacuole, which occupies most of the cell's volume. The vacuole plays various roles such as storing water, maintaining turgor pressure, storing nutrients, and degrading waste products.
4. Plant cells contain chloroplast: This statement is correct. Plant cells contain chloroplasts.Chloroplasts are organelles responsible for photosynthesis, and they are primarily found in the cells of green plant tissues such as leaves and stems.
