What is Sapwood? Sapwood is the outermost layer of wood found in a tree. It is located just beneath the bark and is responsible for transporting water and nutrients from the roots to the leaves of the tree. Sapwood is typically lighter in color than heartwood and is more susceptible to decay and insect damage. … Read more
I. What is Photoperiodism? Photoperiodism is a biological response in organisms, particularly plants, to changes in day length. It refers to the ability of an organism to detect and respond to the length of daylight in its environment. This phenomenon plays a crucial role in regulating various physiological processes in plants, including flowering, growth, and … Read more
What is a Cormophyte? Cormophytes are a group of plants that possess a well-developed vascular system, allowing them to grow tall and compete for sunlight. This group includes ferns, gymnosperms, and angiosperms, which are the most diverse and advanced group of plants on Earth. Cormophytes are characterized by having true roots, stems, and leaves, as … Read more
What are Growth Rings? Growth rings, also known as annual rings or tree rings, are concentric circles found in the cross-section of a tree trunk or branch. These rings represent the growth of the tree over time, with each ring corresponding to one year of growth. By counting the number of rings, scientists can determine … Read more
What is the cortex in plants? The cortex is a vital tissue found in the stems and roots of plants. It is located between the epidermis and the vascular tissues, serving as a protective layer that surrounds the central cylinder of the plant. The cortex plays a crucial role in supporting the plant’s structure and … Read more
I. What is Bark Inclusion? Bark inclusion is a common tree defect that occurs when a branch or stem grows too closely to the main trunk of a tree, causing the bark to become trapped between the two. This results in a weak connection between the branch and the trunk, which can lead to structural … Read more
I. What is a Cotyledon? A cotyledon is a seed leaf found in the embryo of a seed plant. It is the first leaf or pair of leaves that emerge from a seed during germination. Cotyledons are essential for the early growth and development of a plant as they provide the necessary nutrients for the … Read more
What is a gametophyte? A gametophyte is a stage in the life cycle of plants and algae that produces gametes, which are reproductive cells. Gametophytes are haploid, meaning they have only one set of chromosomes. This is in contrast to sporophytes, which are diploid and have two sets of chromosomes. Gametophytes are typically smaller and … Read more
What is an internodal? An internodal is the section of a plant stem that lies between two nodes. Nodes are the points on a stem where leaves, branches, or flowers emerge. Internodes are typically longer than nodes and play a crucial role in the growth and development of plants. What is the function of internodes … Read more
What is Turgor Pressure? Turgor pressure is the pressure exerted by the fluid (usually water) inside the central vacuole of a plant cell against the cell wall. This pressure is essential for maintaining the rigidity and shape of plant cells, allowing them to stand upright and support the weight of leaves, flowers, and fruits. Turgor … Read more
