Microspores vs Megaspores Microspores and megaspores are sexual spores produced by vascular plants (some Pteridophytes and all Gymnosperms and Angiosperms) for sexual reproduction. Both microspores and megaspores on germination produce the respective gametophytic generations. The gametophytes on maturation produce sex organs and gametes to establish the fertilization and thus to […]

Difference between Phase Contrast Microscopy and Differential Interference Contrast Microscopy
Phase Contrast vs DIC Phase Contrast and Differential Contrast Microscopes Phase contrast microscopy and Differential Interference Contrast (DIC) microscopy are two advanced optical light microscopy techniques to produce high contrast images of unstained and living cells. Both the microscopes utilize various contrast enhancing techniques to produce high contrast images. Phase […]

Heterospory and Seed Habit in Pteridophytes
Heterospory is the production of two or more types of spores. It is a condition of the production of more than one types (usually two) of spores in a single plant. These two types of spore differ in their formation, structure and most importantly its functions and sexuality. In Pteridophytes, these […]

Nodal Anatomy of Angiosperms: Unilacunar, Trilacunar and Multilacunar Node
Nodal anatomy refers to the study of the structure and function of nodes of plants, which are the points on a stem where leaves, branches, and buds arise. This includes the examination of the internal and external features of nodes, such as the vascular tissue, meristems, leaf gaps and leaf […]

Anatomical Difference between Dicot (Dorsiventral) Leaf and Monocot (Isobilateral) Leaf – Comparison Table
Dicot Leaf vs Monocot Leaf (Difference between Dorsiventral and Isobilateral Leaf) Dicot leaves are also called as dorsiventral leaves because they possess distinct dorsal and ventral sides. Monocot leaves are called isobilateral leaves since both the sides of monocot leaves are more or less similar. Dicot and monocot leaves show […]
