Irene C Silfa Dr. Brian MettsBiology 1108 7 February 2014 Effect of Temperature on Seed Germination The reproductive cycle of a plant is a process of constant development. It begins with gamete formation‚ and after several other steps leads into germination. During germination a mature seeds beings the formation of a seedling (Freeman 2011). However‚ before germination the seed is in a state of dormancy‚ therefore the seed must have a favorable environment to disrupt the dormancy (Freeman 2011)

effects that one plant has on another plant by the release of chemicals. Allelopathy studies the interactions among plants‚ fungi‚ algae and bacteria with the organisms living in a certain ecosystem‚ interactions that are mediated by the secondary metabolites produced and exuded into the environment (Francisco A Macías‚ José MG Molinillo‚ Rosa M Varela‚ Juan CG Galindo 2007). The plants use allelotoxins‚ which are an allelochemical produced by one plant that is toxic to another plant‚ to help them

Childhood happened like a blur‚ some instances standing out more than others. There is one place which definitely stands out from my childhood; it is in the woods‚ barely a mile away from my house – the place where I used to spend entire days with my friends. I lived on the border of my town‚ all I needed to get to the woods was to cross the narrow road‚ jump off the black old fence which was too short to hold anything in – or out and walk‚ feet shuffling through detritus along the curved path

Some of the most bizarre and fascinating plants in the natural world are undoubtedly carnivorous plants. Carnivory‚ defined as the consumption of animal tissue‚ is often only associated with the animal kingdom. However the existence of carnivory is widespread and diverse in the plant and fungi kingdoms as well. Specifically carnivorous plants‚ which originally descended from exclusively photosynthetic plants‚ have evolved elaborate‚ efficient‚ and diverse methods to capture‚ digest‚ and metabolize

increase rate of growth and increase number of leaves. Materials and Methods The materials used included seeds of Wisconsin fast plants Brassica rapa‚ Styrofoam planting quads‚ potting soil‚ 14- 14- 14- NPK fertilizer beads‚ labeling tape‚ quad wicks‚ plastic water container with wick cloth‚ and anti-algal squares. To construct two different planters for our fast plants we used two Styrofoam planting quads. Each planter and squares inside of the planter were labeled. Each square was filled about half

Plant Transport Plants are mostly made up of water. Lettuce is about 94% water and a potato is about 77% water. Plants need water for three main purposes: ------photosynthesis‚ -support -transport of chemicals Water is a raw material for photosynthesis. If water is in short supply‚ the rate of photosynthesis will be limited. Plants need water for support‚ otherwise they wilt. Water is needed to transport many chemicals within plants. Chemicals‚ such as mineral salts‚ dissolve in water and

"Baby" refers to the embryo‚ or immature plant‚ that will grow and develop into the seedling and ultimately the mature plant. The "suitcase" is the seed coat that surrounds the seeds and "lunch" refers to the nutritive source for the germinating

PLANT CELL Introduction Plant cell is the basic unit of structure and function in nearly all plants. The range of specialization and the character of association of plant cells are very wide. In the simplest plant forms a single cell constitutes a whole organism and carries out all the life functions. In just slightly more complex forms‚ cells are associated structurally‚ but each cell appears to carry out the fundamental life functions‚ although certain ones may be specialized
