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
How do you tell the age of a tree by the rings on the trunk?
You could tell the age of the tree by the rings by counting the rings.The ring equal one year. example: If 500 rings are in the trunk then it will be 500 years.
What is the basic structure of a steroid?
You think probable to the four rings.
What happens when xylem dries up and dies in phloem?
The rings of the tree die or form new rings
What type of vascular tissue makes up tree rings?
In these rings itself the vascular tissue, specially the xylem is gathered in a tree. The phloem remain peripheral to these rings.
What are the rings around the plants made of?
I'm assuming you mean the rings around the planetsinstead of the plants. They are made of dust, rock, and occasionally ice.
Do all the outer plants have rings?
Yes they do
How many plants make up the new Olympic rings at the Royal Botanic Gardens in west London?
The rings are 50m long, made up of 20000 plants
What planet doesn't have rings?
The four inner [terrestrial] planets: Mercury, Venus, Earth and Mars.
Can growth rings be found in plants and animals?
Do your homework and you would know.
What causes annual rings in wood?
The xylem.
What specialized structure is found in C4 plants?
C4 plants have concentric rings of mesophyll cells around vascular bundle sheath in the leaves.
What trait dose not appear in vascular plants?
what causes tree rings to form each year
Which characteristics is common to the four outer plants in our solar system?
They are all gaseous planets with rings systems and many moons.
What are two things uranus Jupiter Neptune and Saturn have that other plants don't?
They have RINGS that surround the Planet, and are 'Gas Giants' without a solid surface.
How is Saturn and uranus similar?
1. Both gas giants 2. they are Jovian planets 3. Both have rings 4. Are both outer plants
