Detailed explanation-1: -Answer and Explanation: The organ system that absorbs nutrients is the digestive system. The organ within this system that absorbs the nutrients is the small intestine.

Detailed explanation-2: -Roots. The roots’ functions are to absorb nutrients and moisture, anchor the plant in the soil, support the stem and store food. Roots are often overlooked, probably because they are less visible than the rest of the plant. However, it’s important to understand plant root systems.

Detailed explanation-3: -Most nutrients are absorbed through root hairs near the very tip of the roots. Root hairs are ultra-fine roots that have a large surface area, allowing them to absorb even more water. The majority of plants also partner with different fungi to absorb even more nutrients from the water in the soil.

Detailed explanation-4: -Its primary functions are anchorage of the plant, absorption of water and dissolved minerals and conduction of these to the stem, and storage of reserve foods.

Detailed explanation-5: -In plants, the process of photosynthesis takes place in the mesophyll of the leaves, inside the chloroplasts. Chloroplasts contain disc-shaped structures called thylakoids, which contain the pigment chlorophyll. Chlorophyll absorbs certain portions of the visible spectrum and captures energy from sunlight.
