Deciduous tree leaves fall in autumn due to a breakdown in cells connecting the leaves to stems. The decreased sunlight in autumn produces a chemical that destroys the connecting cells.

Chia Seed Science Projects Ideas
How to Write a Science Project Question An Experimental Science Project is a Cause/Effect investigation. In other words, the change in one thing causes something else to change. The “Cause” part of the investigation is what you will have control over. The “Effect” part of the investigation is what you will be observing to decide […]
Why Dead Leaves Stay Attached to Stems
When a branch or even a stem is cut from a deciduous tree, why do the leaves stay attached to stems? http://en.wikipedia.org/wiki/Abscission Special cells attach deciduous leaves to stems. In autumn, decreased sunlight triggers the production of chemicals that breakdown the walls of the attaching cells. This results in the leaves falling off of the […]

The Fastest Moving Plant
To date, the fastest moving plant is the White Mulberry (Morus alba). The flower of this mulberry tree shoots pollen at speeds around 200 meters per second. The flower is able to shoot pollen so quickly because its stamens work like medieval catapults. How a Catapult Works A catapult is known as a trebuchet, which […]
Chlelate: Chlorophyll
Chlorophyll is an organic molecule. The basic organic molecule is composed of carbon and hydrogen. More complex organic compounds contain carbon, hydrogen, and other elements such as oxygen and nitrogen. A chelate is an organic compound with a central metal ion. Chlorophyll is one of the most important chelates in nature. In the diagram, the […]
