Learn about the structure of a prokaryotic cell with the help of this beautiful animation. This video covers the description of parts of a prokaryotic cell and their functions as well.
meiosis
Meiosis is essential for sexual reproduction, creating genetic diversity by producing four unique haploid cells from a single diploid cell. Learning about meiosis highlights its role in genetic variation and the continuity of life, emphasizing its importance in evolution and biodiversity.
life cycle of bryophytes
Bryophytes are non-vascular plants, including mosses, liverworts, and hornworts. They thrive in moist environments and play a crucial role in ecosystems by retaining water and nutrients, preventing soil erosion, and providing habitat for small organisms. Their simple structure lacks true roots, stems, and leaves.
life cycle of pteridophytes
Pteridophytes are vascular plants, including ferns and horsetails, that reproduce via spores rather than seeds. They possess true roots, stems, and leaves, often forming lush, green fronds. Thriving in moist, shaded environments, pteridophytes play an essential role in forest ecosystems, contributing to soil formation and providing habitat.
root nodule formation
Root nodules are specialized structures in leguminous plants, formed through a symbiotic relationship with nitrogen-fixing bacteria, mainly Rhizobium. The bacteria infect plant roots, prompting nodule formation, where they convert atmospheric nitrogen into a form the plant can use, enhancing soil fertility and reducing the need for synthetic fertilizers.
secondary growth in roots
Secondary growth in roots involves the thickening of roots through the activity of the vascular cambium and cork cambium. This process produces additional xylem and phloem, enhancing water and nutrient transport. It also forms protective outer layers, aiding in root stability and resilience against environmental stress.
WATER MOVEMENTS IN PLANTS
Turgidity occurs when plant cells fill with water, making them firm and rigid due to the pressure of the cell sap against the cell wall. Plasmolysis happens when cells lose water, causing the cell membrane to pull away from the cell wall, leading to wilting.
