Detailed explanation-1: -Parenchyma cells store food material in the form of oil, fats, proteins, and starch, for example, parenchymatous tissues in roots and stem tubers. So, parenchyma is a simple permanent tissue that helps in storing food in plants.

Detailed explanation-2: -Vacuole: A membrane-bound organelle that helps a cell retain its shape and store things like water, food, and waste.

Detailed explanation-3: -Flame cells function like a kidney, removing waste materials through filtration. The cilia propel waste matter down the tubules and out of the body through excretory pores that open on the body surface; cilia also draw water from the interstitial fluid, allowing for filtration.

Detailed explanation-4: -Flame cells are also known as solenocytes. First of all flame cells were developed as excretory cells phylum Platyhelminthes. So these most primitive types of excretory organs, are called protonephridia. These cells are irregular-shaped and hollow with pseudopodia processes.

Detailed explanation-5: -The cells in the tubules are called flame cells (or protonephridia) because they have a cluster of cilia that looks like a flickering flame when viewed under the microscope.
