Do all vascular plants develop annual rings?
No, they don't.Vascular plants are those which have phloem and xylem structures within them to transport water and nutrients around the plant. Most of the plants you see around you are vascular. Think about grass or herbaceous plants - you won't find growth rings in those if you cut them through the middle, because they do not have cambium in their vascular bundles to initiate secondary growth. Most of the subtropical trees also do not develop annual growth rings although they have cambium because their apical growth never stops.Growth rings occur in plants having cambium and growing in a situation where there is disparity in the seasonal growth. During active growth period, as in spring season, more conduction of raw materials takes place hence the trachieds are broader and during autumn season when the plant prepares for winter, there is lesser conductivity through the xylem elements which makes their trachieds smaller. Thus the rings are caused by differential seasonal growth of xylem elements.----------------------------------In addition, since the tropical climates don't have the large changes in temperature and light hours that the temperate zones have, the vascular, woody plants don't have annual rings. They may form "growth" rings though. If they have a severe dry spell or severe hot or cool spell, or a grass fire, etc., then the tree may develop a pause in active growth and thereby form a "growth" ring. A tree in the tropics could form one growth ring in five years. Then again, it could form five growth rings in one year (that would be a rough year)The term growth ring is a better, more inclusive term than annual ring.Phloem
What would be included as a primary lymphoid tissues?
Primary lymphoid tissue is he place that lymphocytes develop, as opposed to secondary lymphoid tissue where lymphocytes are most active.
What does the cambium do for the plant?
It increases the girth of the stem......................
How does the bark of a tree get food material to survive?
Bark is inactive in a tree but is constantly replaced by the active growth of the vascular cambium- which is just below the bark. Bark is basically a tree's skin on its branches and trunk.Just like damage to skin however, damage to bark (by mowers, scratching, pests, disease) can be very bad for the tree as damage to the vascular cambium could happen.
What are vascular tissues on a plant?
There are 2 types of vascular tissue in plants: xylem & phloem. Xylem is a structurally & functionally complex tissue concerned primarily with water conduction, storage & support. Phloem tissue is also both structurally & functionally complex. Phloem is concerned with the distribution of primarily organic molecules between "sources", that is, photosynthetic or storage tissues, and "sinks", or regions of active growth & metabolism.
