What are Guard Cells? Guard cells are specialized cells found in the epidermis of plant leaves and stems. They are responsible for regulating the exchange of gases, such as carbon dioxide and oxygen, as well as water vapor, between the plant and its environment. Guard cells are unique in that they have the ability to … Read more
I. What is Scarification? Scarification is a process used in botany to break or soften the seed coat of certain seeds to promote germination. The seed coat is the protective outer covering of a seed that can sometimes be too hard or impermeable for water and air to penetrate, hindering germination. Scarification helps to overcome … Read more
What is Somatic Embryogenesis? Somatic embryogenesis is a process in plant tissue culture where somatic cells, or non-reproductive cells, are induced to develop into embryos. This process involves the regeneration of plants from a single cell or a group of cells that are not part of the reproductive organs. Somatic embryogenesis is a powerful tool … Read more
What is a Clonal Colony? A clonal colony is a group of genetically identical individuals that are connected by a network of underground stems, known as rhizomes or stolons. These individuals, also referred to as ramets, are produced asexually through vegetative reproduction. Clonal colonies are commonly found in plants, but can also occur in some … Read more
What is Dendrology? Dendrology is the scientific study of trees and woody plants. It involves the identification, classification, and study of the structure, growth patterns, reproduction, and distribution of trees. Dendrology is a branch of botany that focuses specifically on trees and shrubs, as opposed to herbaceous plants. It is an important field of study … Read more
I. What is Phloem? Phloem is a complex tissue found in vascular plants that is responsible for transporting nutrients, primarily sugars, from the leaves to other parts of the plant. It is one of the two types of vascular tissue in plants, the other being xylem. Phloem is essential for the growth and development of … Read more
What is a whorl in botany? In botany, a whorl refers to a circular arrangement of three or more leaves, flowers, or other plant parts that radiate from a single point on the stem. Whorls are a common structural feature in plants and play a crucial role in plant identification and classification. How are whorls … Read more
What is an understory? The understory is the layer of vegetation that grows beneath the canopy of taller trees in a forest or woodland ecosystem. It is characterized by lower light levels and competition for resources from the larger trees above. The understory plays a crucial role in the overall health and diversity of the … Read more
What is Tissue Culture? Tissue culture is a technique used in botany to propagate plants from small tissue samples under sterile conditions. This method involves growing plant cells, tissues, or organs in a nutrient-rich medium in a controlled environment. By providing the necessary nutrients and hormones, plant cells can divide and differentiate to form new … Read more
What is Photosynthesis? Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy, usually from the sun, into chemical energy stored in glucose molecules. This process is essential for the survival of plants and other organisms that depend on them for food. How does Photosynthesis work? Photosynthesis occurs in the … Read more
