• Mitochondria are responsible for producing energy through respiration.
• The nucleus is the control centre of the cell, containing DNA which controls all activities within the cell.
• Ribosomes are small structures that play a role in protein synthesis.
• Chloroplasts contain chlorophyll, which absorbs light energy to produce glucose during photosynthesis.
• Vacuoles store substances such as food or waste products inside the cell.
• Cell membranes regulate what enters and exits the cell.
