Chloroplasts,her plastids, such as etioplasts, leucoplasts, amyloplasts, and chromoplasts, develop either by division of an existing plastid or from proplastids. It is generally accepted that plastids are derived from a single endosymbiotic event in the ancestor of glaucophytes, red, and green algae (which was t

The Endoplasmic Reticulum, Golgi Apparatuses, and Endocytic Organelles,roteins and lipids or the Golgi apparatus for polysaccharides and terminates at the cell surface or lytic/vacuolar compartments. In addition to the exocytic pathway, the endocytic pathway is also a vesicular transport system. The ER is a network of membrane-bound flattened sacs and tubules which man

Cytoskeletons,t appear to be very active when compared to animal cells. However, the skeletal feature of the cytoskeleton function is only one component of its reality. When a plant cell forms and alters its shape, the cytoskeleton is intimately involved. Additionally, plant cells actively relocate some cellular

Typical cell walls in land plants are composed predominantly of polysaccharides, mainly cellulose microfibrils, which are embedded in a matrix of pectin and hemicellulose. Cellulos

Generative Cells,on, the mode of mating has changed from isogamy to unisogamy, and, finally, to oogamy. In parallel, the mating process has become progressively less dependent on the presence of external water. In algae, bryophytes, and pteridophytes, male gametes are flagellated sperms which move to eggs by swimmin
