Plant structure and function
Let’s delve into more detail about plant structure and function: Plant Structure: Roots: Function: Roots have several essential functions, including anchoring the plant in the soil, absorbing water and minerals, and storing carbohydrates. Types: Taproots: A single, large, central root, typical in dicotyledonous plants. Fibrous roots: A network of fine, slender roots, common in monocotyledonous…
How do plants know when to flower?
Phytochrome, a blue-green pigment, is part of a switching mechanism for phototropic responses to light of red and far-red wavelengths. Its active form, Pfr might trigger the secretion of one or more hormones that induce and inhibit flowering at different times of yeat. The main environmental cue for flowering is the length of night, i.e.…
