By replacing a fridge bought in 1990 with an Energy Star-qualified model, you could save enough energy to light a household for nearly four months, according to the U.S. Department of Energy (DOE). To find a list of Energy Starapproved models, log on to energystar.gov.
This article is about vascular tissue in plants. For transport in animals, see Circulatory system. Vascular tissue is a complex conducting tissue, formed of more than one cell type, found in vascular plants. The primary components of vascular tissue are the xylem and phloem. These two tissues transport fluid and nutrients internally. There are also two meristems associated with vascular tissue: the vascular cambium and the cork cambium. All the vascular tissues within a particular plant together constitute the vascular tissue system of that plant. The cells in vascular tissue are typically long and slender. Since the xylem and phloem function in the conduction of water, minerals, and nutrients throughout the plant, it is not surprising that their form should be similar to pipes.
Confidence votes 1.2K. The vascular tissue system is one of three tissue systems that make up a plant, the other two tissue systems or ground and dermal, with dermal tissue being the outer layer and the ground tissue making up most of the inside of a plant. plant's vascular system is composed of two networks of hollow tubes, similar to our veins and arteries. Each network consists of a different type of vascular tissue that works to move different resources throughout the plant. These vascular tissues would be the tissues known as xylem and phloem.
