Angiosperm Embryo Sac Types – Three Main Embryo Sac Types and Its Variations

Angiosperm Embryo Sac Types

Angiosperm Embryo Sac Types – Monosporic Embryo Sac, Bisporic Embryo Sac, Tetrasporic Embryo Sac Angiosperm embryo sac mainly are of three types. The first one is monosporic embryo sac; the second one is known as bisporic embryo sac and the last one is called tetrasporic embryo sac. We previously studied development of female gametophyte, which is a Normal Type 8 – nucleate monosporic embryo ...

Process of Photosynthesis Step by Step

Process of Photosynthesis

Process of photosynthesis is utilized by autotrophic organisms such as green plants, algae and cyanobacteria (photosynthetic bacteria). They use the photosynthesis process step by step in order to make their own organic nutrients from simple inorganic nutrients (water, carbon dioxide and minerals) and radiant energy. The radiant energy is converted into chemical energy of specific organic compounds, mainly sugars and ...

Ovule Development – Megasporogenesis, Types of Embryo Sac, Female Gametophyte

Ovule Development

Ovule Development In Angiosperms – Megasporogenesis in Angiosperms, Embryo Sac Types, Female Gametophyte In Angiosperms Ovule development takes place by appearance of primordium as a protuberance on the surface of the placenta. It grows into a conical structure with rounded tip. This is the Nucellus or Megasporangium Proper. From the base of the nucellus, one or two layers of tissue develop, which ...
