plant tissue

• plants have organs this are called- vegetative organs
• meristematic tissue- able to divide or grow because they have nucleus
• permanent tissue- do not grow
• apical meristem- (height/length) primary meristem, found in the stems/roots/shoots
• cambium- a ring of meristematic tissue
• lateral meristem- (width/widening of the plants) secondary meristem
• intercalary- found in monocot plants
• dermal tissue- covers and protects the plants
• vascular tissue- transport water, minerals, and sugars
• ground tissue- serves as site for photosynthesis
• parenchyma- thin walled, food storage, able to divide
• collenchyma- thick walled, support the plant, with pectin and cellulose
• sclerenchyma- dead cells, support to mature plants, with lignin
• lignin- organic substance that is responsible for the hard and tough cell wall of the plant
• sclerenchyma divided two structure- fiber and sclereids
• fiber- elongated
• sclereids- irregular shape
• xylem- transport water
• phloem- solid transport, downward and upward movement
