Updated On: Aug 1, 2022
- they secretes enzyme outside the body and absorbes
- they have mycorrhiza with fungi
- they takes food and then digested it
- they are photosynthetic
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
The saprophytic plants perform external digestion. They excrete hydrophytic enzymes into the external medium. These enzymes are celluloses, chitinases, amylases, proteinases etc. They hydrolyse different components of organic matter and then the simple and soluble substances are absorbed.

Concepts Used:
Angiosperms
A type of plant belonging to the kingdom Plantae is angiosperms. The term Angiosperm is acquired from two Greek words: Angio - ‘covered’ and Sperma - ‘seed’. They are the types of plants that contain flowers which is a well-defined feature and the seeds are enfolded within the fruits. Since they can bear both flowers and seeds are also called flowering plants, and also comprises around 80% of the living plants.
The Characteristics of Angiosperms are:
- The body of an angiosperm is evidently differentiated into several organs such as leaves, flowers, fruits, roots, stems, and seeds.
- Among these organs the decision of labor is well-coordinated, and each organ is peerlessly specialized for specific functions.
- Out of all angiosperms, most of them are herbs, shrubs, trees, climbers, etc.
- A vessel is the chief water and mineral that conducts Xylem elements.
- The sieve tube is the chief food that conducts Phloem elements.
- Endosperm has triploid cells.
- The angiosperms are basically divided into two groups, based on the presence of the number of cotyledons in the seed. They are
- Dicotyledonous or Dicot plants
- Monocotyledonous or Monocots Plants
