Lesson 1

• The structure of plants includes the parts of the leaf, which can be classified into leaf classifications such as leaf stem, roots, and flower.
• The structure of plants includes the parts of the leaf, such as the petiole, lamina, and venation.
• Parts of the leaf include the petiole, lamina, and venation.
• Leaf an essential life process, where photosynthesis occurs
• Photosynthesis the process of using sunlight, water, and carbon dioxide to make sugar.
• Blade (lamina), a flat, broad section and largest part of the leaves. That contains cell that perform photosynthesis.
• Veins, a tubelike structure which carry water, minerals and sugar throughout the blades
• Monocot a leaf veins are usually parallel
• Dicot leaf veins are usually branched
• Petiole, a short stalk that connects the leaf to the stem
• Midrib, travels the length of the leaf and branches to each side to produce veins of vascular tissue
• Margin, edge of the leaf
• Simple, a leaf with an undivided blade
• Compound leaf, a leaf where the blade is divided, formong leaflets
• Palmately compound leaf, a leaf that has its leaflets radiating outwards from the end of the petiole
• Pinnately compound leaf, a leaf where the leaflets are arranged along the middle vein
• Stem, support system for the plants that act as delivery agents for the nutrients and water stored in the roots and transferring them to the other plant parts in the form of glucose
• Roots, responsible for transferring the necessary nutrients to the plant
• Taproot, single large central root with much smaller side roots branching out from it
• Fibrous root, form of a clump short, threadlike divisions
• Flower, reproductive organ of flowering plant that are not only involved in reproduction, but are also a source of food for other living organisms
• seed, reproductive structure consisting of a plant embryo and its stored food
• fruit, house and protect seeds and many also help disperse from to new locations
