Plants are Produces Jinny, Terry, and Cindys X-File of 2.2
Do you like Science? Plants: Plants are living organisms belonging to the kingdom Plantae Procedure: A procedure is a series of actions or operations which have to be executed in the same manner in order to always obtain the same result under the same circumstances.
Contents Plants capture energy from the Sun Producing Sugars Storing and Releasing Energy Plants are adapted to different environments Plants Respond to their environment Gravity Touch Light Plants respond to seasonal changes
Key words Key Words Photosythesis: the process in which plants capture energy from sunlight and convert it to chemical energy Autothroph: another name for plant. It means self-feeder.
Producing Sugar/X-File X-File 1: Plans capture energy from sunlight and convert it to chemical energy through the process of photosynthesis X-File 2: Plants are referred to as producers because they produce energy-rich carbon compounds using the Suns energy.
Producing Sugar/X-File X-File 3: The cells, tissues, and organ systems in a plant work together to supply materials needed for photosynthesis. X-File 4: The leaves take in carbon dioxide from the air, and the stems support the leaves. The roots anchor the stem and supply water.
Producing Sugar/X-File X-File 5: Plants do not require food from other organisms X-File 6: Plants will grow if they have energy from the Sun, carbon dioxide from the air, and water and nutrients from the soil.
Key Words Cellular respiration: the process by which a cell uses oxygen to break down sugars to release the energy they hold.
Restoring and Releasing Energy/X- File X-File 1: Plants are not the only organism that capture energy through photosynthesis. However, plants are from single-celled producers. X-File 2: Only part of the energy captured by a plant is used as fuel for cellular process
Restoring and Releasing Energy/X- File X-File 3: Starches, energy rich compound made of many sugars can store a lot of chemical energy X-File 4: When a plant needs energy, the starches are broken back down into sugars and energy is released.
Plants are adapted to different environments/X-File X-File 1:Just as there are man different types of land environments, there are man different types of plants that have adopted to these environments. X-File 2: A coniferous tree, such as a pine tree, does well in colder climates, while a deciduous tree, such as a maple, loses its leaves when the temperature turns cold.

Key Point Stimulus: something that produces a response from an organism
Gravity/X-File X-File 1: Gravity is the force that keeps us bound to earth and gives us a sense of up and down. X-File 2: All plants respond to gravity; the roots grow down and the stems grow up
Touch/X-File X-File 1: Many plants also respond to touch as a stimulus. X-File 2: Peas, morning glories, tropical vines, and other climbing plants have special stems called tendrils, which is respond to the touch of a nearby object. X-File 3: The twining of tendrils around a fence or another plant helps raise a plant into the sunlight.
Light/X-File X-File 1: Light is a powerful stimulus for plants, (you can see that stems and leaves grow toward light by placing an indoor plant near a window). X-File 2: Plants respond to light with the help of hormone (a chemical substance that is produced in one part of an organism and travels to a different part where it produces a reaction.)
Light/X-File X-File 3: Auxin, a plant hormone that stimulates cell growth, is produced at the tip of a plant stem. X-File 4: Auxin moves away from light. X-File 5: As a result, the cells on the darker side of a plant stem contain more auxin than those on the lighter side.
