atmosphere and remove oxygen produced in photosynthesis. During photosynthesis the chloroplasts in the leaf cells synthesize as a result of exposure to light‚ while oxygen is produced as a by-product. As the outer leafs are exposed to higher light levels the stomatal density has to be high and because the inner leaves are exposed to lower light levels they will so have a lower stomatal density than the outer leafs. This is known as an adaptation‚ (leaves in the centre of a shrub are exposed to small amounts

branched‚ smooth‚ succulent herb‚ 0.4 to 1.4 meters in height. Leaves are simple or pinnately compound‚ with the leaflets elliptic‚ usually about 10 centimeters long‚ thick‚ succulent‚ and scalloped margins. Plantlets grow along the notches of the leaf margins which can develop while still attached to the plant or when detached‚ a fascinating characteristic that earns its name. Flowers are cylindric‚ and pendulous in a large‚ terminal panicle. Calyx is tubular‚ cylindric‚ inflated‚ brownish or purplish

Variagated Leaves Total absence of plastid pigments causes a sector of a leaf or stem to have white patches. This condition is termed variegation (Metrosideros). Variegation is produced when there is a cell mutation (cytological chimera)‚ and all cells produced from that mutant mother cell lack the pigments‚ either because plastids are not present or the plastid cannot complete the manufacture of the pigment apparatus. White‚ therefore‚ is where color is missing. The zones where chloroplasts are

have one cotyledon in seed while dicots have two. Xylems and Phloem are in circular shape in dicots‚ while monocots’ are scattered. Monocots have the multiples of 3 petals while dicots can have 4/5 petals. Monocots have parallel leaf veins while dicots have branched leaf veins. Safety Precautions: 1. Use care when cutting the seeds with scalpel 2. Exercise extreme care‚ scalpel are extremely sharp. 3. Inform the teacher if the investigator has a food allergy 4. Wash hands thoroughly

The stylistic analysis of the text “The last leaf” by O.Henry. I would like to tell you a story “The last leaf” written by O. Henry. William Sydney Porter (September 11‚ 1862 – June 5‚ 1910)‚ known by his pen name O. Henry‚ was an American writer. O. Henry’s short stories are known for their wit‚ wordplay‚ warm characterization and clever twist endings. None of his stories can leave the reader cold blooded. All the stories have deep sense‚ make you debate a matter in your mind and have a lot of

together in tissues. A tissue can be simple or complex depending upon whether it is composed of one or more than one type of cell. Tissues are further arranged or combined into organs that carry out life functions of the organism. Plant organs include the leaf‚ stem‚ root‚ and reproductive structures. The first three are sometimes called the vegetative organs and are the subject of exploration in this chapter. Reproductive organs will be covered in Chapter 5. The relationships of the organs within a plant
