Biology Unit Test #1 Review

• This is a parenchyma cell. They are the thickest cells with the thinnest cell wall and they perform most of the metabolic function of the plant (photosynthesis). They also store organic produce (glucose). They have primary walls (single cell wall)

  
• This is a collenchyma cell. They support young parts of the plant shoot and elongate as well as strengthen. They are shaped as a cylinder and have primary walls (single cell wall)

  
• This is a sclerenchyma cell. Its main function is to support elements in the plants. It contains large amounts of lignin (indigestible strengthening polymer). It has 2 cell walls (primary and secondary)
