to west (side to side) along the globe, but that measure distances
north and south of the equator |
leaf
|

usually green, growing laterally from the stem or twig of a plant:
it usually consists of a broad blade, a petiole, or stalk, and
stipules and is involved in the processes of photosynthesis and
transpiration |
longitude

of a leaf that connects it to a branch of a tree or bush |
photosynthesis
|
1) the biological synthesis of chemical
compounds in the presence of light. 2) the production of organic
substances, especially sugars, from carbon dioxide and water
occurring in green plant cells supplied with enought light to
allow chlorohhyll to aid in the transformation of the rediant
energy into a chemical form |
pinnate
|
1) resembling a feather 2) bot. with
leaflets on each side of a common axis in a featherlike arrangement |
plant
|
a living organism that, unlike an animal,
cannot move voluntarily, has the ability to synthesize food from

in the sky in the morning from a particular location |
sunset
