LEAF ADAPTATION The main function of the leaf is in the processes of photosynthesis and transpiration. Apart from these functions, leaf is sometimes adapted to perform other functions. Examples of leaf adaptations are for: a) Support, which could be seen by the presence of tendrils b) Catching insects, by having cup-liked shape of hairs sensitive to touch c) Reproduction, by having meristematic cells able to produce new shoots that will go on to become new individual plants d) Food and water storage, especially found in plants living in dry areas where water is scarce (for example succulent plants, having leaf storing food and water) e) Floatation, for plants living on the water surface, their leaves in general will have air openings on tissues (used for floating) usually found on leaf petiole f) Protection, by having leaves completely or partially modified as thorns Instruction: a) 1.

- 1. Examine the shoot system of a mature plant. Identify the shoot tip, nodes, internodes,leaves, and axillary buds. Note that axillary buds always occur above a leaf. Axillary buds giverise to branch shoots. Thus, branching in a shoot system is exogenous (of external origin).How does this compare to branching in a root system?2. Examine a longitudinal section through a Coleus stem tip. Identify the apical meristem, leafprimordia (developing leaf), bud primordia (developing axillary buds), nodes, and internodes.Beginning with the apical meristem, follow the development of shoot tissues. Identify protoderm, procambium, and ground meristem, pith, and cortex. A) You will not be able to identify any mature cells or tissues in this slide (keep in mind thesize of theshoot tip). What are the mature tissues that each of these primary meristems become?B) Can you find a node (where procambium diverges in to the leaf primordium)? These areasare also commonly called Aleaf gaps@. However, because…arrow_forwardOPE Examining a flower50 1. Flowers are borne on stalks or pedicels in the axils of modified leaves called bracts. As mentioned previously, flowers may occur singly or in a cluster. Examine at least one of the flowering shoots provided and determine the floral arrangement. (Write the answer in #7.) 2. Using a pair of forceps, remove the outer green sepals of a single flower. Record the number. 3. Remove and record the number of petals. (If more than 12, put numerous.) 4. Remove and record the number of stamens. 5. The structure remaining is the pistil. 6. Use a sharp scalpel to cut a horizontal slice from the ovary. Place this on a slide and observe the cut surface with the stereomicroscope. Observe the ovules. Record the number of compartments or carpels in the ovary. 7. Take another of the same flower. Hold it upside down between the first finger and thumb. Carefully cut it with a scalpel into two halves along the plane of symmetry.
