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 else can I help you with?
Does vascular cambium Increase in thickness of stems over time result from the production of vascular tissue.?
yes it does the pourpose of the cambium is to thicken the plant . I'm not sure if im right, but i think your wrong. Only woody plants have a vascular cambuim. One of the most common woody plant is a tree. If you are talking about a vascular cambium inside a tree, then no, the vascular cambuim does not expand the stem. What it does is make a second layer of bark for the tree in the comming spring.
What type of vascular tissue makes up tree rings?
Tree rings are formed by the growth of two types of vascular tissues: xylem and phloem. Xylem is responsible for transporting water and minerals from the roots to the rest of the plant, while phloem helps transport sugars and other nutrients produced in the leaves to other parts of the tree. The formation of these tissues in a tree's trunk leads to the annual growth rings that can be seen in the cross-section of a tree trunk.
Do blackberry bushes have annual rings?
Blackberries produce canes from the roots each year which only live for two years-- the first year cane, called a primocane, usually doesn't produce fruit. If it survives to the 2nd year, it's called a floricane and produces fruit and then dies, so if there are annual rings, there are only 2 of them.
What distinguishes xylem and phloem from other tissues?
Xylem and phloem are vascular tissues. They are tissues that form tubes in plants. Xylem carries water and minerals contained in water that is drawn up from the ground through the roots. Phloem carries food produced in leaves down and up to other parts of plants. In trees, the phloem is located just inside the bark. It is a fairly narrow region. The part of trees called wood is the xylem. A layer called the vascular cambium is located between the xylem and phloem. It produces xylem to the inside and phloem to the outside. Growth rings in tree trunks are xylem. Plants like mosses, liverworts and horn worts don't have vascular tissues. Water, minerals, and food move around these plants very slowly. The movement is from one cell to another then another, and so on. Nonvascular plants are small and must grow in moist places. Vascular plants are larger because materials can move around in them quickly.
Which life process is responsible for the ringsn tree trunks?
The process responsible for the rings in tree trunks is called annual growth rings. Each year, trees go through periods of growth and rest which results in the formation of a new ring in their trunk. Counting these rings can reveal the age of the tree.
What trait dose not appear in vascular plants?
what causes tree rings to form each year
What specialized structure is found in C4 plants?
C4 plants have concentric rings of mesophyll cells around vascular bundle sheath in the leaves.
Where does the vascular tissue gather in rings that show the age of trees?
In these rings itself the vascular tissue, specially the xylem is gathered in a tree. The phloem remain peripheral to these rings.
Does vascular cambium Increase in thickness of stems over time result from the production of vascular tissue.?

The band of vascular tissue that is formed during each growing season is called?
The band of vascular tissue formed during each growing season is called the growth ring or annual ring. These rings can be seen in the cross-section of a tree trunk and can be used to determine the age of the tree and its growth patterns.
What are annual growth rings most common in?
Annual growth rings are commonly studied in trees.
What type of vascular tissue makes up tree rings?
Tree rings are formed by the growth of two types of vascular tissues: xylem and phloem. Xylem is responsible for transporting water and minerals from the roots to the rest of the plant, while phloem helps transport sugars and other nutrients produced in the leaves to other parts of the tree. The formation of these tissues in a tree's trunk leads to the annual growth rings that can be seen in the cross-section of a tree trunk.
Is a conifer a vascular plant?
Yes, all trees are vascular. The rings inside them are vascular tissue (xylem and phloem) as are the veins in there leaves and roots. Vascular tissue is tubing. All plants are vascular except algae, mosses, liverworts, and hornworts.
What are other word for growth rings?
annual rings
Annual rings provide about a tree?
The annual rings provide the age of the tree, one annual ring equals one year of growth.
14 Annual rings in woody stems are caused by an increase in rings of the?
Annual rings in woody stems are caused by an increase in rings of the secondary xylem. Secondary xylem tissue is produced by vascular cambium. It is also caused by increased and decreased activity of cork cambium during spring and winter, respectively.
How tree rings formed?
EASY EXPLANATION Trees form rings (also known as annual growth rings) because in temperate regions the vascular cambium, a type of lateral meristem that causes growth of secondary xylem, becomes dormant during the winter and later resumes growth in the spring. Because the cells are much smaller right before dormancy compared to the large cells right after dormancy, there is a clear difference, or ring, that is visible. This process occurs periodically every winter (every year), resulting in annual growth rings.SLIGHTLY LESS EASY EXPLANATIONVascular tissues of plants are of two types1. Xylem2. PhloemAnd these 2 tissues are again of 2 types1. Primary2. SecondaryThe primary vascular tissues are present in all vascular plants and are formed from a primary meristem called PROCAMBIUM . The secondary vascular tissues are found only in dicot plants because they develop from a special kind of meristem ( lateral ) called VASCULAR CAMBIUM which is seen only in dicots. The production of secondary vascular tissues is called SECONDARY GROWTH.The vascular cambium produces secondary xylem to its inner side and secondary phloem to its outer side.During spring, there is more activity in the plant due to the formation of new leaves, etc, hence the increased need for more water supply and thus more secondary xylem with large lumen is produced. This wood appears light in colour and is called EARLY WOOD or SPRING WOOD.During autumn all the leaves fall off and there is not much need of xylem and hence the activity of vascular cambium decreases and less xylem with narrow lumen are produced. This wood appears dark and is called LATE WOOD or AUTUMN WOOD.Thus every year two types of wood are formed which appear as a ring called ANNUAL RING or GROWTH RING.
