The starch grains mainly contain starch which is produced from photosynthesis
Cellulose is the found in plant cell walls, it is needed to strenghten these (it forms microfirbils). Starch is the energy store in plants, so used in respiration Thanks The Plant Doctor
starch grains store food for plant cell .the starch grain just re-produces on and on. but like the Amyloplast, amyloplast gives away starch grain in its cell.
The major purpose of a potato cell is for storing starch. Potatoes are underground stems that store energy reserves in the form of starch, allowing the plant to survive and grow during periods when photosynthesis is not actively occurring.
cellulose
starch
Polysaccharides like starch are stored as insoluble food material in plant cells and cellulose comprise the cell wall etc.
The organelle that serves as a storage area for starch in a plant cell is the plastid, specifically the chloroplast. Starch is stored in the form of granules in the chloroplasts and can be broken down into glucose when needed by the plant for energy.
a cell wall is absent in a plant cell and cell sap is also not there in animal cell ,starch grains
The colour for a plant cell's starch grains is typically blue or black when stained with iodine solution. This is due to the formation of a complex between iodine and starch, which results in the characteristic colour change.

Starch is stored in plant cells in organelles called amyloplasts. Amyloplasts are specialized plastids that specifically accumulate and store starch granules. They are commonly found in storage organs such as roots, tubers, and seeds.
Most of the starch contained in a leaf is located within chloroplasts.
