Characteristics that uniquely identify plants: they are autotrophic‚ non-motile‚ they are photosynthetic‚ contain chloroplast‚ perform alternation of generations‚ plants are deciduous or evergreen‚ and the type of leaf and stem structure they have (http://wiki.answers.com/Q/What_characteristics_do_all_plants_share). Most plants are autotrophic‚ meaning they are capable of producing their own food and nutrients themselves‚ synthesizing their own food from inorganic substances‚ by using light or

Today photosynthesis is widely known across the globe‚ and with all of its reactions. It is often broken into two steps: the “light” reactions and the “dark” reactions. Both of these reactions are fundamental to the process of photosynthesis‚ and photosynthesis is vital for plants to survive. Because plants are the main energy source for organisms on Earth‚ and without them‚ we could not survive‚ photosynthesis is extremely important in the study of life‚ biology. Without Melvin Calvin‚ however‚

For example‚ rose bushes and humans are highly complex organisms‚ made up of cells that are specialized in their form and function. For example‚ rose bushes contain cells that house chloroplasts. Without chloroplasts‚ the rose bush would not be able to synthesize its own food. Humans‚ on the other hand‚ have cells that carry oxygen‚ produce special chemicals (such as insulin)‚ and protect our bodies from invaders. Although different cells perform

Chromatography Biology 1107L Introduction All living organisms require energy for their chemical processes. The ultimate source of this energy is the sun. Plants convert light energy into the chemical energy of sugars. During photosynthesis pigments are used to capture light energy. Pigments of green plants can easily be separated and identified using a technique called paper chromatography. The purpose of this experiment is to separate the pigments using paper chromatography.

[pic] Cells and Their Organelles The cell is the basic unit of life. The following is a glossary of animal cell terms. All cells are surrounded by a cell membrane. The cell membrane is semipermeable‚ allowing some substances to pass into the cell and blocking others. It is composed of a double layer of phospholipids and embedded proteins. Color and label the cell membrane tan. Plant cells have an additional layer surrounding them called the cell wall. The cell wall is made of nonliving

is known as photosynthesis and is the basis for sustaining the life processes of all plants. Since animals and humans obtain their food supply by eating plants‚ photosynthesis can be said to be the source of our life also. As the chlorophyll in leaves decays in the autumn‚ the green color fades and is replaced by the oranges and reds of carotenoids. Xanthophyll is the yellow pigment in plants that‚ like chlorophyll‚ is responsible for the production of carbohydrates by photosynthesis. Chromatography
