In aquatic plants, parenchyma tissue plays a crucial role in buoyancy and gas exchange. Specialized parenchyma known as aerenchyma is formed in these plants. Aerenchyma consists of loosely arranged parenchyma cells with large intercellular air spaces. This tissue provides buoyancy to keep the plant afloat in water, aiding in the efficient exchange of gases, particularly oxygen and carbon dioxide, between the submerged parts of the plant and the surrounding water. Aerenchyma facilitates oxygen transport to submerged roots and other tissues, preventing oxygen deficiency, and is an adaptation to the unique challenges faced by plants in aquatic environments.
Besides food storage, parenchyma tissue is involved in various processes in plants. It plays a key role in photosynthesis, containing chloroplasts that capture sunlight and convert it into energy. Parenchyma cells are also crucial for gas exchange, allowing the movement of gases like oxygen and carbRead more
Besides food storage, parenchyma tissue is involved in various processes in plants. It plays a key role in photosynthesis, containing chloroplasts that capture sunlight and convert it into energy. Parenchyma cells are also crucial for gas exchange, allowing the movement of gases like oxygen and carbon dioxide. In addition, parenchyma participates in wound healing and tissue regeneration. Its versatility extends to functions such as secretion, supporting plant growth and adaptation. Overall, parenchyma tissue serves diverse physiological roles, contributing to the plant’s structural integrity, metabolism, and response to environmental stimuli.
Meristematic tissues are classified into three categories based on their locations in plants: 1. Apical Meristem: Found at the tips of roots and shoots, apical meristems are responsible for primary growth, lengthening the plant body. 2. Lateral (or Axillary) Meristem: Present in the lateral buds, laRead more
Meristematic tissues are classified into three categories based on their locations in plants:
1. Apical Meristem: Found at the tips of roots and shoots, apical meristems are responsible for primary growth, lengthening the plant body.
2. Lateral (or Axillary) Meristem: Present in the lateral buds, lateral meristems contribute to secondary growth by increasing the girth or thickness of stems and roots. The vascular cambium and cork cambium are examples of lateral meristems.
3. Intercalary Meristem: Located at the base of leaves or internodes, intercalary meristems promote growth in specific regions. They play a role in regenerating tissues, particularly in grasses and certain herbaceous plants.
The apical meristem in plants serves a crucial function in primary growth by promoting elongation of the plant body. Located at the tips of roots and shoots, it is responsible for the lengthening of these structures. The apical meristem produces new cells through rapid cell division, contributing toRead more
The apical meristem in plants serves a crucial function in primary growth by promoting elongation of the plant body. Located at the tips of roots and shoots, it is responsible for the lengthening of these structures. The apical meristem produces new cells through rapid cell division, contributing to the formation of primary tissues. In roots, apical meristems aid in downward growth, facilitating nutrient and water absorption. In shoots, they promote upward growth, aiding in the development of leaves and branches. The continuous activity of apical meristems ensures the primary growth and structural development necessary for the plant’s adaptation and survival.
Lateral meristems contribute to the growth of plant stems and roots through secondary growth, increasing the girth or thickness of these structures. The two main types of lateral meristems are vascular cambium and cork cambium. The vascular cambium produces secondary xylem and phloem, adding layersRead more
Lateral meristems contribute to the growth of plant stems and roots through secondary growth, increasing the girth or thickness of these structures. The two main types of lateral meristems are vascular cambium and cork cambium. The vascular cambium produces secondary xylem and phloem, adding layers to the stem’s interior. This results in increased structural support and efficient water and nutrient transport. Cork cambium produces cork cells, forming the protective outer bark of the stem. Together, these lateral meristems contribute to the development of woody tissues, enhancing the overall strength and resilience of plant stems and roots, a process vital for perennial plants and trees.
