-Dermal tissue is composed of epidermal cells, closely packed cells that secrete a waxy cuticle that aids in the prevention of water loss. The dermal tissue system protects the soft tissues of plants and controls interactions with the plants' surroundings. The epidermis is a dermal tissue that is usually a single layer of cells covering the younger parts of a plant.
-Vascular tissues include xylem, which conducts water and minerals from the roots upward and throughout the plant, and phloem, which transports dissolved nutrients in all directions within the plant.
This was Ernest Rutherford’s gold foil experiment. He used radioactive alpha particles as a part of the experiment and discovered that there was a densely packed, positively charged nucleus in atoms with electrons that were spread out in spaces between nuclei.
