  1. Specialized cells are cells that perform a particular function, such as growth or absorbing water. A tissue is a group of specialized cells that perform a similar task. Demonstrate the difference between a plant cell and plant tissue by making five basic plant cell models, using the previous procedure. Put the lid on each box. Place two of the cell model boxes on top of two others to create two stacks, each two cells high. Place the fifth box near the two stacks. Fold 2 index cards in half. Label one card Plant Tissue and stand it in front of the two stacks. Label the other card Plant Cell and stand it in front of the fifth box. Display the boxes and photograph them. Use the photographs to prepare a poster to represent the difference between a plant cell and plant tissue.
  2. Organs are structures consisting of different tissues grouped together to perform a specific function or functions. Plants have several organs. Leaves are special plant organs for manufacturing food. Roots and stems are special plant organs for absorbing (taking in) and transporting (carrying from one place to another) water, food, and minerals throughout the plant. Some plants have flowers, which contain organs for producing more plants. Find out more about these and other plant organs. Create and display a chart showing the different plant organs.
