Step by step
Solved in 3 steps
- Explain structural adaptations necessary for the invasion of dry plants and also state which adaptations are possessed by nonvascular plants, ferns and by gymnosperm and angiosperm.Identify three major functions of roots. Describe two types of specialized stems. What is each type of stem specialized for? Discuss the main parts of an angiosperm leaf. Predict how the stem of a desert plant might be specialized for its environment. Contrast a taproot system with a fibrous root system. Relate leaf variation to environmental variation.Compare and contrast the germination of a typical monocot and eudicot seed by addressing the following:a. Explain the anatomy of a monocot and eudicot seed by naming and defining their various parts.
- Label the internal parts of the following cross sections of monocot and eudicot plants:Examine the shoot system of a mature plant (Coleus blumei). Identify the shoot tip, nodes, internodes, leaves, and axillary buds. Each unit of stem that consists of a leaf, axillary bud and internode is referred to as a phytomere. Note that axillary buds always occur above a leaf. Axillary buds give rise to branch shoots. Thus, branching in a shoot system is exogenous (of external origin). How does this compare to branching in a root system?Identify what plant group contains the following characteristic: 1. Leaves that resemble palms, and with cones in the center 2. Leaves that resemble a needle, and with cones at the branch 3. Possess strobilus that are club-like 4. Have xylem and phloem for nutrient transport 5. Have gemmae in the thallus 6. Don't have leaves in the stem and appears as whisk-like 7. Have sporophyte that resembles horns 8. Have flowers
- Describe the tissue hierarchical organization and structure of a bamboo. Describe or draw examples of each level.Sketch a seed of a gymnosperm and of a monocot. Label the embryo, seed coat, and nutritive tissue (giving its specific name). Indicate the ploidy of each structure (haploid, diploid, or triploid).Provide a picture and label a diagram that illustrates the following features: holdfast (a root-like structure that attaches the seaweed to the bottom), stipe (a stem like structure, but not a true stem because it lacks vascular tissues), blades (leaf-like structures, but not true leaves because they lack veins), and pneumatocyst (an air-filled float).
- Examine the winter twig in the picture below of a Horse Chestnut tree, Aesculus hippocastanum. w.m. Draw a sketch of this twig and label all the following structures: terminal bud, lateral bud, terminal bud scale scars (show several sets of terminal bud scars that are visible on the main stem), leaf scars, vascular bundle scarsExamine an image of longitudinal section through a Coleus stem tip. Draw the apical meristem, leaf primordia (developing leaf), bud primordia (developing axillary buds), nodes, and internodes. How many phytomeres are present in this preparation? Beginning with the apical meristem, follow the development of shoot tissues. Label protoderm, procambium, and ground meristem, pith, and cortex. You will not be able to identify any mature cells or tissues in this slide (keep in mind the size of the shoot tip).What are the mature tissues that each of these primary meristems become?Identify the anatomical structures of a woody twig.
