have to find a way to get the sunlight they require‚ some live in an aquatic environments where there is an abundance of water‚ and some live in desert environments where it is dry and very hot. These plants have different adaptations such as leaf size‚ leaf surface‚ stem size‚ and their stress level. In this lab‚ we will be discussing plants from 3 different regions; forest‚ aquatic‚ and desert‚ and describe some of their adaptations that allows them to live and prosper. Evenezer Tekie [pic][pic]

Water Transport in Plants Introduction In this lab experiment‚ we set out to examine the different transpiration rates of a plant system in certain environments. Water is transported in a plant by the process of transpiration‚ which is the loss of water through evaporation from the surface of leaves. The stomata in leaves are responsible for the diffusion of water vapor. Transpiration brings water upward through the xylem in the plant. There are certain factors that can affect transpiration

Adaptations of Savanna vegetation. Savanna vegetation must adapt to survive. Many problems must be overcome‚ such as lack of water‚ very seasonal rainfall‚ poor soil quality‚ grazing animals‚ very high temperatures and fire. 1. Define the following terms: Xerophytic = A plant adapted to living in a dry arid habitat; a desert plant Pyrophytic = plants adapted to tolerate fire Deciduous = Loss of leaves seasonally Perennial = lives more than 2 years Dormant = A condition of significantly

Premium Leaf Pollution Photosynthesis
(Leafed cuttings) These cuttings are prepared from soft‚ woody plants just as they are about to reach full maturity. Shoots are most suitable for making softwood cutting when they can be snapped easily when bent and when they still have a gradation of leaf size. For most woody plants this stage mainly occurs during the period May-July. The soft shoots are usually handled with care and must be kept away from drying out. 75-125mm long with two nodes or more. Semi-Hardwood Cuttings These cuttings are

photosynthesis to take place. The stomata is the way in which these gases are exchanged‚ as well as the transpiration of water from the xylem‚ either by the apoplast or symplast pathway. Palisade cells are positioned towards the upper surface of the leaf and contain the largest number of chloroplasts per cell in plants. This makes them the primary site of photosynthesis in a plant’s leaves. They have a very large surface area in order for them to absorb more light during photosynthesis. This makes

Premium Plant Seed Agriculture
TOMATO PLANT 1) Seed: Tomato seeds are small‚ flat and disk shaped and about 1/8 inch wide. They contain two energy storage organs called cotyledons and an embryo encased in a hard outer shell called the seed coat. The seed is the dormant or resting stage of the plant life cycle. When young tomato plants are damaged‚ they tend to go into a dormant‚ survival stage in which plant growth is delayed for a while. Frost damage is something to look out for when planting tomatoes early on in the season
