Which tissue stores food in plants?

QUESTION: Which tissue stores food in plants?


  • The tissue that stores food in plants is called parenchyma tissue
  • Parenchyma cells are found in various parts of a plant, including the stems, roots, leaves, and fruits.
  • They are characterized by their thin cell walls, large central vacuoles, and the ability to store various substances, including food reserves.
  • In plants, parenchyma cells can store food in the form of starch, oils, proteins, or other organic compounds.
  • These food reserves are stored in the vacuoles or within specialized structures called plastids, such as amyloplasts for starch storage or oleoplasts for oil storage.
  • The storage of food in parenchyma tissue serves important functions in plants, such as providing a reservoir of energy and nutrients during times of growth, development, or periods of dormancy.
  • It allows plants to store excess carbohydrates produced during photosynthesis for later use in various metabolic processes, including growth, reproduction, or as a source of energy during unfavorable conditions.
  • Starchy Parenchyma found in organs such as tubers (e.g., potatoes) and rhizomes (e.g., ginger), where it stores starch as a source of energy.
  • Endosperm: A specialized tissue found in seeds, particularly in monocotyledonous plants. It serves as a nutrient-rich storage tissue to support the developing embryo.
  • Fruit Parenchyma: In certain fruits, parenchyma tissue stores sugars and other carbohydrates, contributing to the fruit’s sweetness and serving as a food source for seed dispersal.
Characteristic Description
Location ·        Found throughout the plant body, including stems

·        Roots

·        Leaves

·        Fruits






·        Storage: Parenchyma cells store food reserves, such as starch, oils, proteins, or other organic compounds.

·        Photosynthesis: Some parenchyma cells carry out photosynthesis, containing chloroplasts for producing energy-rich compounds.

·        Gas Exchange: Parenchyma tissue allows for gas exchange between cells, contributing to plant respiration.

·        Wound Healing: Parenchyma tissue aids in the regeneration and repair of injured plant tissues.

Cell Structure ·        Thin cell walls

·        large central vacuoles

·        living protoplasts

Specializations ·        Starchy Parenchyma: Specialized parenchyma cells that store starch as a source of energy.

·        Water-Storing Parenchyma: Parenchyma cells in succulent plants that store water, contributing to their drought resistance.

·        Aerenchyma: Parenchyma tissue with large air spaces, enabling buoyancy in aquatic plants or facilitating gas exchange in roots.
Examples ·        Parenchyma tissue is found in a wide range of plant organs, including pith, cortex, mesophyll, and various storage tissues.

·        Examples include potato tubers, leaf mesophyll, fruit pulp, and the inner parts of stems and roots.
