At the very least, one-third of the more than 9,250 vascular plant species native to the country are endemic. [3] There are, however, no plant families endemic to the country. [4] The families of gingers, begonias, gesneriads, orchids, pandans, palms, and dipterocarps are particularly high in endemic species. For example, two-thirds of the 150 ...
Structure of a plant cell. Plant cells are the cells present in green plants, photosynthetic eukaryotes of the kingdom Plantae.Their distinctive features include primary cell walls containing cellulose, hemicelluloses and pectin, the presence of plastids with the capability to perform photosynthesis and store starch, a large vacuole that regulates turgor pressure, the absence of flagella or ...
Palisade cell, or palisade mesophyll cell are plant cells located inside the mesophyll of most green leaves. They are vertically elongated and are stacked side by side, in contrast to the irregular and loosely arranged spongy mesophyll cells beneath them. Palisade cells are responsible for carrying out the majority of the photosynthesis in a ...

An example is Sardinella tawilis, a freshwater sardine found only in Taal Lake. Lake Lanao, in Mindanao, seems to be experiencing the country's most catastrophic extinction event, with nearly all of the lake's endemic fish species now almost certainly extinct, primarily due to the introduction of tilapia for the expansion of the fishing ...
These cells, along with the epidermal guard cells of the stoma, form a system of air spaces and chambers that regulate the exchange of gases. In some works, the cells of the leaf epidermis are regarded as specialised parenchymal cells, [ 4 ] but the modern preference has long been to classify the epidermis as plant dermal tissue , and ...
