Plant species can be categorized into saprophytes and symbionts based on their nutritional habits. Saprophytes thrive on decaying organic matter, while symbionts rely on other living organisms for their sustenance.

Understanding Saprophytes

Saprophytes are unique plants that derive their nutrients from decomposed organic material. They lack chlorophyll, which is why they are referred to as non-green plants. These plants typically flourish on dead wood, decomposing waste, and fallen leaves. They possess enzymes that help them break down organic substances into simpler forms.

Defining Symbionts

Symbionts, on the other hand, establish close associations with other plants from which they obtain their nutrition. Their relationships can be categorized into three types –

  • Mutualism: Both organisms benefit from this relationship.
  • Commensalism: One organism benefits while the other remains unaffected.
  • Parasitism: One organism benefits at the expense of the other.

Now, let's delve into their differences.

Saprophytic Plants

Symbiotic Plants

Definition

Saprophytic plants, or saprophytes, utilize dead and decomposing organic matter for their nourishment.

Symbiotic plants, or symbionts, establish close relationships with other organisms for their nutrition.

Types
