If a seed is exposed to these vital needs, it goes through a process called germination. According to the Wise Geek article, “What is Germination?”, “Germination is a process in which a seed or spore awakens from dormancy and starts to sprout.” (“What is Germination?”). The writer of Botany Projects for Young Scientists says, “The seed usually goes through a dormant, or resting period after it has left the parent plant. During this time, it can endure cold or dry conditions.” they later go on to say, “When warmth and moisture become available, the seed germinates and forms a new plant.” (Bleifeld 60). In laboratory settings, germination tests are conducted to see how long it takes seeds to germinate.

Quadrat: - Another special equipment used in this experiment, which helps identify and clarify the sizes of classified trees and grass. Meter Ruler: - Suggest roughly the sizes of the trees branches and the measurements of its thickness. Method ====== In a group of 5, we decided to find a clear spot were the Quadrat could be thrown, in order to analyse our leaves and plants. After we threw the Quadrat three times, we managed to identify the individual plants which consisted of smaller grass and more/less bugs. We then used the compass to direct us towards a tree in a certain area.
The three species of trees are the radermachera, geranium and Osman thus. After that, I put the leaf samples in the plastic bags that labelled with the position and tree species. Then I traced each leaf on a piece of graph paper. I counted the number of squares that occupied by the leaves to figure out the area of the leaf samples and record them on the data table (see the table below).
Kent and Cooker (1992) stated that identification of plant through special characteristic and physiological structure that the taxonomic nomenclature has applied in botanical flora. A quadrat surveys conducted surrounding the University of Greenwich at Medway, which focused to identify the plant in a grassland area and invertebrate. Grassland is relatively simple in soil structured in contrast with the complexity of woodland and more likely to have greater dispersed organic matter intensities than in forest soils (Curry, 1994). The objective of this study is to classify the plant characteristics, the vegetation types, and the dynamic environment for the plant. Furthermore, some of the characteristics of invertebrate populations and the causes of presence will addressed as well.
The growing tip of the root will emerge from the seed, and the root will begin to grow. (The Columbia Encyclopedia, 6th ed., 2008) All vascular plants have roots, which are multicellular organs used to secure the plant in the soil and absorb water and nutrients. (Campbell, Reece, Urry, Cain, Qasserman, Minorsky & Jackson, 2008) The root also stores carbohydrates, which is a product used in photosynthesis. (Whiting, D., 2011) The root has a root cap at the tip of the root to protect the apical meristem, which is a tissue in control of the root’s growth. Although it is not visible to the naked eye, the root cap benefits the root greatly.

He also include that the plant can be maintained and monitored in the regulated environment like greenhouse so that the reduction in crops production cause by the seasonal change can be avoided. Plant tissue culture is referring to the “aseptic culture of cells, tissue, organs, and their components under defined physical and chemical conditions in vitro” (Thorpe, 2006, p.9). According to Odutayo, Amusa, Okutade and Ogunsanwo (2007), single pieces of plant from the stem tip, node, meristem, embryo and seed can be used for the multiplication of plant and induces in the sterile medium for its growth. As elaborated by Reed (n.d), there are three important steps involved in plant tissue culture namely preparation of explant, multiplication and transplanting (refer to Figure 1 in Appendix 1). The first step is preparation of explant.
