Iodine binds to starch and would be primarily used to stain plant cells. The organelles that would be stained darkest would be the nucleus, amyloplast, which store starches, and chloroplasts which produce it.
Plants store food in the form of starch, which is a complex carbohydrate made up of glucose molecules. Starch is stored in specialized plant structures like roots, tubers, and seeds, where it can be broken down later to provide energy for growth and metabolism.
Plant cells have a cell wall, chloroplasts for photosynthesis, and a large central vacuole, which are not present in animal cells. Animal cells have centrioles and lysosomes, which are typically not found in plant cells.
The cell wall of plant cells is mainly composed of cellulose, a complex carbohydrate made up of long chains of glucose molecules. In addition to cellulose, plant cell walls also contain other components such as hemicellulose, pectin, and lignin, which provide structural support and protection to the cell.
because the leaves have photosynthesized- glucose is produced. therefore, the excess glucose is converted to starch. The starch is then stored in the leaf-starch is what causes the "green" leaf to turn blue black, as iodine turns blue-black when it reacts with starch.:P
Starch granules in plants serve as storage molecules for energy. They are used as a reserve of carbohydrates for the plant to use during times of low energy production, such as at night or during periods of low photosynthesis.
Cell walls, Chloroplasts, Starch granules
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 starch grains mainly contain starch which is produced from photosynthesis
cellulose
starch
You would test the leaves of the plant for starch. Starch is produced through photosynthesis in the leaves, so they are the best part of the plant to test for the presence of this carbohydrate.
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 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.
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.
