Here's why:

* Cell Walls: These are rigid structures that provide support and protection for plant cells. They are made primarily of cellulose.

* Chloroplasts: These are organelles within plant cells that are responsible for photosynthesis, the process of converting sunlight into energy. They contain chlorophyll, the pigment that gives plants their green color.

Therefore, all plants have cell walls and chloroplasts, including:

* Fruits: Apples, oranges, bananas, strawberries, etc.

* Vegetables: Spinach, broccoli, carrots, potatoes, etc.

* Grains: Rice, wheat, corn, etc.

* Legumes: Beans, lentils, peas, etc.

* Nuts: Almonds, walnuts, peanuts, etc.

* Seeds: Sunflower seeds, pumpkin seeds, etc.

While there are some foods derived from plants that may not have intact cell walls or chloroplasts, such as refined grains and certain processed foods, the original plant source did possess both.
