Any of a group of green pigments that capture light energy used as the energy source in photosynthesis and that are found in the chloroplasts of plants and other photosynthetic organisms such as cyanobacteria, especially:
a. A waxy blue-black microcrystalline green-plant pigment, C55H72MgN4O5, with a characteristic blue-green alcohol solution. Also called chlorophyll a.
b. A similar green-plant pigment, C55H70MgN4O6, having a brilliant green alcohol solution. Also called chlorophyll b.

Accordingly, lateral buds differentiated in rosette galls of Pisphondylia brasiliensis (Cecidomyiidae) on Guapira opposita (Nyctaginaceae) produce true chlorophyllous leaf primordia (Fleury et al., 2015).
In addition to nutritive tissue formation, structural and physiological alterations, such as decreases in the amount of chlorophyllous tissues, pigment content, gas exchange, and photosynthetic rates, have been detected in gall tissues (Florentine, Raman, & Dhileepan, 2005; Oliveira et al., 2011b; Oliveira, Moreira, Isaias, Martini, & Rezende, 2017).
Calli formed in both protocols were generally milky, friable, and when present, the leaf primordia become chlorophyllous two to five days after light exposure.
Spore germination and viability in pteridophyta: evolutionary significance of chlorophyllous spores.
However, longevity has been related to abiotic and biotic factors, such as spore type, traditionally named as green (chlorophyllous) and non-green (non-chlorophyllous) (LLOYD; KLEKOWSKI JR., 1970), and considered recalcitrant or orthodox, respectively, based on the typical classification used for seeds (ROBERTS, 1973).
The chlorophyllous protocorms underwent morphogenetic changes leading to pseudobulb and leafprimordial formation which subsequently developed into complete seedlings with leaves and roots in 10 weeks (Figure 1(b)).
After elimination of chlorophyllous cuticle, leaves were cut into regular pieces, rinsed with water, dried for 72 h at 50[degrees]C, milled twice to obtain a very fine powder and preserved at -20[degrees] C prior to analysis and extraction.
