Solution

Epidermal cells are the outermost layer of cells in plants and they play a crucial role in protecting the plant from water loss, regulation of gas exchange, secretion of metabolic compounds, and absorption of water and mineral nutrients.

  1. Vacuoles: Present in epidermal cells. They are large organelles that store water and nutrients needed by the cell.

  2. Nucleus: Present in epidermal cells. It controls cell activities such as metabolism, growth, and reproduction by controlling protein synthesis.

  3. Mitochondria: Present in epidermal cells. They are the powerhouses of the cell, producing energy for cell activities.

  4. Chloroplasts: Absent in epidermal cells. Chloroplasts are the site of photosynthesis in plant cells. However, they are typically absent in epidermal cells because these cells are not directly involved in photosynthesis.

So, the answer is Chloroplasts are absent in epidermal cells.
