Chloroplasts
The Phloem
Spongy mesophyll cells are not packed so tightly together, which allows carbon dioxide and oxygen to reach the palisade cells where they are needed in photosynthesis. Spongy mesophyll cells and guard cells (see below) also get some photosynthetic action.
No, xylem cells are "dead" cells and therefore do not undergo cell division.
xylem cells are *~!BLUE!~* because of the presence of lignin
A layer of cambium cells separates the xylem and phloem tubes.
In the middle of the leaf, in line with the xylem cells (under the palisade cells but above the stomata)
The Phloem
they are the objects inside a cross-section of a leaf which are loosley packed cells that give the leaf a spongy appearence.

yes the xylem is one of the plant tissues the others are phloem and the palisade layer. the plant organs are the stem, leaf and roots.
a) xylem and phloem b) cambrium and epidermis c) chloroplasts and guard cells d) palisade and spongy layers ?
Waxy cuticle, Palisade cells, spongy mesophyll, vascular bundle (xylem, phloem). Plant cell : Nucleus, vacuole, cytoplasm, centriole, lysosomes, cell membrane, cell wall. etc etc.
Cuticle
No, xylem cells are "dead" cells and therefore do not undergo cell division.
the xylem transports water and the phloem transports organic substances.
The nutrients and water are in the soil, the root hair cells which are in the roots help absorb them, then they travel up the xylem and into the palisade layer of the leaf which is where chlorophyll and chloroplasts are and it is also the location of photosynthesis
