Plants are photosynthetic and use chlorophyll to capture sunlight and eventually turn it into energy. Most plants are covered in a waxy covering called a cuticle to keep it from drying out. The root of plants is an organ that pulls in nutrients and water, stores starches and keeps the plant anchored. The stem is an organ that holds the plant upright and transports nutrients and water. Only vascular plants have stems.
Most plants are vascular plants and have vascular tissues.
Vascular tissues are made of longer than usual cells that act as tubes. Larger plants need vascular tissues to get the nutrients and water everywhere. Smaller plants that are lower to the ground where nutrients just travel from one cell to another. There are two categories of plants, seed plants and non-seed plants. Seed plants have a seed with food, surrounded by a protective coating, sometimes a fruit.
