    you are: a Mineral food

    Now, when we have considered the mineral elements necessary for normal growth of plants, it is necessary to discuss, as they arrive in a plant from an external world. mineral substances are usually absorbed from soil by means of roots. As they can arrive in small amounts as well through leaves, extraroot entering of some microcells became a standard agricultural method. mineral substances are almost always absorbed by a plant in the form of ions. These ions should cross at first plazmalemmu to get into cytoplasm, and then and a membrane surrounding vakuol or any cellular organellu to get to this or that internal kompartment cytoplasms.
