Title: Identifying Morphological Parts, Growth Habit and Seeds of Grasses and Legumes
Abstract:
The purpose of this laboratory report is to identify and describe the morphological parts, growth habit, and seeds of grasses and legumes. The experiment involved observing various samples of grasses and legumes, recording their characteristics, and comparing them to existing knowledge. The experiment aimed to enhance our understanding of plant morphology and to learn how to differentiate between these two important plant families.
Introduction:
Grasses and legumes are two distinct plant families commonly found in various ecosystems. Both groups have economic importance in agriculture, horticulture, and the environment as they serve as sources of food, forage, and ecosystem restoration. Morphological identification of grasses and legumes is essential for botanical classification and understanding their growth habits and seed structures. This laboratory report provides a detailed account of the identification process of these plant families through careful observation and comparison of their morphological parts, growth habit, and seeds.
Materials and Methods:
1. Various samples of grasses and legumes (provided by the instructor)
2. Microscopes
3. Plant identification guides and resources
4. Scalpels
5. Forceps
6. Magnifying glasses
7. Rulers
8. Camera for documentation
1. Morphological Parts Identification:
1.1. Observe each grass and legume sample under a microscope and using magnifying glasses to aid in visualizing plant structures.
1.2. Record the characteristics of the plant structures, including leaves, stems, roots, inflorescences, flowers, and fruits.
1.3. Compare the observed characteristics with plant identification guides and resources to determine the family (grass or legume) to which each sample belongs.
2. Growth Habit Determination:
2.1. Observe and record the growth habit (such as prostrate, erect, or climbing) of each grass and legume sample.
2.2. Measure the height of each sample using a ruler to quantify their growth habit characteristics.
3. Seed Structure Recognition:
3.1. Use scalpels and forceps to gently extract seeds from the grass and legume samples.
3.2. Examine the shape, size, color, and surface texture of each seed using microscopes and magnifying glasses, recording detailed observations.
3.3. Compare the seed characteristics with known examples from identification guides and resources to confirm their association with grasses or legumes.
Results:
1. Morphological Parts Identification:
The observed characteristics of grasses included parallel-veined leaves, hollow stems with nodes, fibrous root systems, spike-like inflorescences, and grains as the fruit. Legumes, on the other hand, exhibited compound leaves, solid or hollow stems with nodes, taproot systems, various inflorescence types (racemes, umbels, or heads), and pods as the fruit.
2. Growth Habit Determination:
Grasses generally displayed an erect growth habit, ranging in height from a few centimeters to several meters. Meanwhile, legumes exhibited a wide range of growth habits, including prostrate, erect, and climbing, with heights varying accordingly.
3. Seed Structure Recognition:
Grass seeds were observed to be small, with varying shapes (ovate, linear, or elliptical) and surface textures (smooth or rough). Legume seeds were larger, often rounded or oblong in shape, and possessed a smooth or textured surface. The color of the seeds varied between different grass and legume species.
Conclusion:
This laboratory report successfully identified and described the morphological parts, growth habit, and seeds of grasses and legumes. Through careful observation and comparison with known identification guides and resources, the samples could be differentiated into their respective families. This exercise enhanced our understanding of plant morphology and further emphasized the significance of morphological characteristics in systematic plant identification.
