What type of cells contain chloroplasts?

Chloroplasts are specialized organelles that play a critical role in photosynthesis, allowing certain cells to capture light energy and convert it into chemical energy stored in glucose. Plant cells and algae cells are the primary types of cells that contain chloroplasts, enabling them to perform photosynthesis.

In plant cells, chloroplasts are specifically adapted for maximizing light absorption and facilitating the complex biochemical processes required for converting carbon dioxide and water into glucose and oxygen, utilizing sunlight. Algae, being aquatic organisms that can be unicellular or multicellular, also possess chloroplasts that serve the same purpose, keeping these organisms self-sustaining in terms of energy production.

The other options do not contain chloroplasts. Animal cells rely on consuming organic matter for energy and lack the cellular structures necessary for photosynthesis. Bacterial cells, while diverse and capable of various metabolic processes, do not have chloroplasts; some can perform photosynthesis using different types of pigments but do so in a different cellular structure known as thylakoids, not chloroplasts. Fungal cells are heterotrophic organisms that absorb nutrients from their environment and do not have chloroplasts either.

Therefore, the presence of chloroplasts is characteristic of plant and algae cells,
