Ryan Tudino Mrs. Couchon Biology Honors/ 1A 10 April 2013 Abstract The seeds of summer squash (Cacurbita moschata)‚ beet (Beta vulgaris)‚ and pepper (Capsicum annuum) are all dicot plants‚ which mean that they have two seed leaves inside the seed coat. When they are placed in an environment and are watered with solutions of different acidic and alkaline levels‚ the root growth during germination is affected. The purpose of this experiment was to observe what type of substance‚ acidic or basic

DNA is typically has two strands running in opposite direction and is usually referred to as a double helix. Each on the individual strands consists of a backbone that is formed by sugar molecules linked together in groups. Each individual sugar molecule is covalently linked to one of the following possible bases: Adenine‚ Guanine‚ Cytosine and Thymine. These bases

A less rigid structure: water pressure supports them. 5. Flat leaves on surface plants for flotation. 6. Air sacs for flotation. 7. Smaller roots: water can diffuse directly into leaves. 8. Feathery roots: no need to support the plant. 9. Specialized roots able to take in oxygen. Floating All floating plants

Carnivorous Plants In a world where plants are at the bottom of the food-chain‚ some individual plant species have evolved ways to reverse the order we expect to find in nature. These insectivorous plants‚ as they are sometimes called‚ are the predators ‚ rather than the passive prey. Adaptations such as odiferous lures and trapping mechanisms have made it possible for these photosynthesizers to capture‚ chemically break-down and digest insect prey (and in some cases even small animals.) There

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
