Science Test Tomorrow

All science information is reviewed thoroughly in class. This study guide will help you to do well tomorrow on the vascular plants test.

 ·         Know how to read a table and interpret data like in our celery experiment

·         Understand that the control vial of water lets us know how much water was lost due to evaporation.

·         Know that celery with leaves soaks up more water than celery without leaves.

·         Be able to ask questions and make a hypothesis about an experiment regarding celery with and without leaves.

·         Be able to compare and contrast the circulatory systems in animals and plants: Both systems transport food and water to cells. However, in animals blood is transported around and around the body. In a plant, there are 2 one way systems that transport water and food. Xylem transports water and minerals up, and the phloem transports sugar down and to all the cells in the plant.

·         Be able to label pinnate, palmate, and parallel leaf veins. If a plant has the same veins, the same shape, and the same leaf margins then it could have come from the same plant.

·         Leaves that come from the same plant have to have the same type of veins AND leaf margins.

·         Be able to describe how water in the ground travels to the leaves in the top of a tree: Water enters the tree through the roots. The water flows up the roots and tree in the xylem tubes. The xylem tubes carry the water all the way to the leaves at the top of the tree. Excess water is evaporated.

·         When we used red dye in the celery experiment then cut it, it showed a cross section of xylem tubes. The xylem tubes were dyed red to show how the stalk took up water. The xylem tubes transport water through the stalk to the leaves.
