from the aerial parts of plants‚ especially leaves but also stems‚ flowers and roots. Leaf surfaces are dotted with openings called stomates that are bordered by guard cells. Collectively‚ the structures are called stomata.[1] Leaf transpiration occurs through stomata‚ and can be as a necessary "cost" associated with many processes such as the opening of the pistil and allowing the diffusion of carbon dioxide gas from the air for photosynthesis. Transpiration also cools plants and enables mass flow

Plant hormones are specialized chemical substances produced by plants. They are the main internal factors controlling growth and development. Hormones are produced in one part of a plant and transported to others‚ where they are effective in very small amounts. Depending on the target tissue‚ a given hormone may have different effects. Plant hormones play an integral role in controlling the growth and development of plants. A plant hormone is generally described as an organic compound synthesized

PLANT BODY Two Categories of Plant cells: 1.) Meristematic cells – embryonic‚ undifferentiated and capable of cell division • Apical meristem – located at root and shoot ends • Lateral meristem – run parallel to the long axis of roots and stems – where somatic cells undergo mitosis 2.) Differentiated/Permanent Cells – specialized in structure and usually do not divide • Simple Permanent Tissue – dermal tissue system and ground tissue system › Dermal tissue system – outer surfaces of

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

Aquatic plants: Fixed plants Fixed plants are held in place by their roots which grow in the water-bed. The Water Lily and Lotus are such plants. Their stems are long‚ hollow and light. These stems reach the surface of the water. The leaves and flowers‚ which grow from the top end of the stems‚ float upon the water. The leaves are broad with stomata on the top surface so that the water does not block them. Lotus The roots of lotus are planted in the soil of the pond or river bottom‚ while

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
