Rhizoids are not directly involved in nutrition. They are root-like structures found in non-vascular plants like mosses, liverworts, and hornworts. They primarily function in anchoring the plant to the substrate and absorbing water and minerals.

The actual nutrition of these plants is carried out through photosynthesis in their chloroplasts. This means they are autotrophic, meaning they make their own food using sunlight, water, and carbon dioxide.

Here's a breakdown:

* Rhizoids: Structural support, water and mineral absorption.

* Chloroplasts: Photosynthesis, production of food.

* Nutrition Type: Autotrophic
