Funaria is a moss you’ll often find thriving in damp, shady areas like forest floors or along stream banks. Unlike typical plants, it lacks true roots, stems, or leaves, absorbing water and nutrients directly through its surface. If you take a closer look, you’ll spot its vibrant green tufts topped with tiny, capsule-like structures—these hold … Read more

Curious about gymnosperms and their role in the plant kingdom? Whether you’re wondering, “Is a pine tree a gymnosperm?” or “What’s the difference between gymnosperms and angiosperms?”, this guide unlocks the answers. Gymnosperms (from the Greek for “naked seeds”) are a group of seed-producing plants that include conifers, cycads, and ginkgos. Unlike angiosperms (flowering plants like the petunia, which is an angiosperm), gymnosperms do not produce … Read more

What are Tissues? Definition of Tissues Tissues are groups of similar cells that work together to perform specific functions in an organism. They serve as the structural and functional units that form organs, playing critical roles in various biological processes. Characteristics of Tissues Location of Tissues Formation of Tissues The formation of tissues, known as … Read more

Pollen-pistil interaction is a critical phase in plant reproduction, acting as a sophisticated biological dialogue between male pollen grains and the female reproductive structure, the pistil. When pollen lands on the stigma—the sticky tip of the pistil—it doesn’t immediately guarantee fertilization. Instead, the pistil initiates a series of biochemical checks to assess compatibility. These interactions … Read more

What is Microsporogenesis? Definition of microsporogenesis Microsporogenesis is the process in which diploid microspore mother cells undergo meiosis to form haploid microspores, which eventually develop into pollen grains in plants. Where does microsporogenesis occur? Structure of Stamen Structure of microsporangium Process of Microsporogenesis in Plants In flowering plants, microsporogenesis is the process by which precursors … Read more

What are Plant Tissues? Plant tissues are organized cell groups within a plant that collectively enable essential life functions, like growth, protection, and nutrient transport. There are two main categories of plant tissues: meristematic and permanent. Meristematic tissues contain actively dividing cells that promote growth. Found in regions like root and shoot tips, these cells … Read more

What is Transpiration? Types of Transpiration Transpiration in plants occurs through several distinct pathways, each playing a specific role in water movement and evaporation. These pathways are classified into four primary types: stomatal, cuticular, lenticular, and bark transpiration. Factors affecting Transpiration Transpiration is influenced by a variety of factors that can be classified into two … Read more

Wha is Stomata? Definition of Stomata Stomata are tiny pores located on the epidermis of plant leaves and stems that regulate gas exchange, allowing carbon dioxide, oxygen, and water vapor to enter and exit the plant. Each stoma is flanked by guard cells that control its opening and closing, facilitating processes such as photosynthesis and … Read more
