Option 1 states that plant cells have fewer mitochondria than animal cells. This statement is incorrect. In reality, plant cells typically have more mitochondria than animal cells. Mitochondria are responsible for energy production through cellular respiration, and plant cells require a lot of energy for activities like photosynthesis.

Option 2 states that plastids in a plant cell are organelles enclosed by a single membrane. This statement is correct. Plastids, such as chloroplasts, are specialized organelles found in plant cells that function in processes like photosynthesis. They are surrounded by a double membrane.

Option 3 states that the Golgi complex in a cell participates in the recycling of the plasma membrane. This statement is correct. The Golgi complex plays a role in modifying, sorting, and packaging proteins and lipids. It can also participate in the recycling of cellular components, including the plasma membrane.

Based on these explanations, the correct answer is Option 2 (II and III). Option 1 is incorrect because plant cells have more mitochondria than animal cells.
