fy`llon leaf: cf. F. chlorophylle.]
1. (Bot.) Literally, leaf green; a green granular matter
formed in the cells of the leaves (and other parts exposed
to light) of plants, to which they owe their green color,
and through which all ordinary assimilation of plant food
takes place. Similar chlorophyll granules have been found
in the tissues of the lower animals. [Written also
chlorophyl.]
[1913 Webster]
2. any of a group of green pigments found in photosynthetic
organisms. Chlorophyll a and chlorophyll b are found
in higher plants and green algae; chlorophyll c is found
in certain types of marine algae. Chemically, it has a
porphyrin ring with a magnesium ion bound to the four
central nitrogens, and has a phytyl side chain. It is
essential for photosynthesis in most plants. {Chlorophyll
a} has formula C55H72N4O5Mg.

layer 4
X.214
X.224
(Or "host-host layer") The middle layer in the
OSI seven layer model. The transport layer determines how
to use the network layer to provide a virtual error-free,
point to point connection so that host A can send messages to
host B and they will arrive un-corrupted and in the correct
order. It establishes and dissolves connections between
hosts. It is used by the session layer.
An example transport layer protocol is {Transmission Control
Protocol} (TCP).
