Leaves are the organs of the shoot system adapted for photosynthesis. They often consist of a petiole and a blade. Leaves differ with respect to their arrangement on the venation, and shape.
In this chapter we will discuss the form and anatomy of leaves, describe their development, and note the modifications that help plants deal with environmental challenges. The leaves of dicot and monocot plants (defined in Chapter 5) have similar functions, but their basic designs differ.
standard set of terms for describing leaf form and venation, particularly of dicots. This manual also provides a template and set of instructions that show how descriptive information can be entered into a standardized database of fossil and extant leaves. The Leaf Architecture Working
Describe a range of modifications in plant structure and relate these to their function. Describe the structure and function of flowers, fruit and seed. Describe the differences between monocotyledon and dicotyledon plant structure. Relate plant morphology and structures to management practices.
learn about plant structure, to introduce the use of a field guide to the common woody plants on campus. Plants are photosynthetic autotrophs which are also structurally complex. The tissues of higher plants are organized into roots, stems, and leaves which are the organs of the plant body. The leaf and the stem, together, make up the shoot.
the plant. The third tissue system, the ground tissue system, is important for photosynthesis and storage. Tissue systems in turn create the stems, leaves, roots and reproductive organs of plants. This book was created to support teaching of an introductory unit on plant environmental physiology at Charles Darwin University. It makes use of various
17 gru 2021 · The arrangement of leaves on a stem is known as phyllotaxy. The number and placement of a plant’s leaves will vary depending on the species, with each species exhibiting a characteristic leaf arrangement. Leaves are classified as either alternate, spiral, opposite, or whorled.
