What is the difference between the arrangement of vascular tissue in the stems of dicots and monocots?
In young dicot and monocot stems do not increase in thickness. Xylem and phloem are arranged in vascular bundles in the cortex. In older stems and all woody stems, the vascular tissues form a cylinder between the cortex and the pith. The vascular bundles in a monocot are scattered throughout the stem.
What is the different internal structure of stem?
Stems typically have three main internal structures: dermal tissue (outer protective covering), vascular tissue (transport system for water and nutrients), and ground tissue (storage and support). These structures work together to provide structural support, transport water and nutrients, and store reserves for the plant. The arrangement and organization of these tissues vary among different plant species.
What is the difference between vascular cambium and cork cambium?
The vascular cambium adds to secondary xylem and secondary phloem while the cork cambium gives rise to cork and secondary cortex. The vascular cambium is a remnant of the apical meristem while the cork cambium is a true secondary meristem which develops outside the vascular tissues.
What is the correct definition of periosteum?
The periosteum is a dense layer of vascular connective tissue that covers the outer surface of bones. It plays a vital role in bone growth, repair, and nutrition by providing a site for muscle attachment and containing bone-forming cells. Additionally, the periosteum is involved in the sensation of pain and regulates bone thickness.
What componenet of the plasma membrane forms most of the cell's outer boundary?
The human cell has three principal parts which are the plasma membrane, cytoplasm, and the nucleus. The outer boundary is the plasma membrane.
What are amphivasal vascular bundles?
When xylem is surrounded by phloem from outer as well as inner sides, the vascular bundles are called amphivasal
What is the difference between the arrangement of vascular tissue in the stems of dicots and monocots?
In young dicot and monocot stems do not increase in thickness. Xylem and phloem are arranged in vascular bundles in the cortex. In older stems and all woody stems, the vascular tissues form a cylinder between the cortex and the pith. The vascular bundles in a monocot are scattered throughout the stem.
What would the pattern of vascular tissue would you expect if you cut the plants stem if it had five petals?
The vascular bundles would be arranged in a ring around the pith. The flower would be a dicot, because the four characteristics of dicots are: ~flower parts in fours or fives ~two cotyledons (embryonic leaves) ~veins in leaves branch out ~vascular bundles are arranged in a ring
What is separated from the vascular cylinder?
The endodermis forms a barrier around the vascular cylinder, separating it from the outer cortex in the root. This layer helps control the movement of water and nutrients into the vascular tissue.
How are vascular tissue arranged in dicot stems?
They form a ring where phloem forms an outer ring around the xylem.
How does the outer core help the earth?
In more complex diagrams they show that we have an outer core. actually we do have but not for any chemical properties but for the slight difference in temperature. It helps in forming the magnetic sphere around us.
Grafting palm tree?
Generally speaking, monocots (such as palm) can not be grafted since the vascular cambium is distributed in discrete bundles throughout the stem instead of on the outer ring like dicots (such as apple tree)---so you can't "line up the plumbing" and the plant can't get nutrients across the graft so it dies :(
Is a leaf made of a cells?
A typical leaf has an outer (epidermal) layer, pores (stomato) surrounded by a pair of guard cells, middle tissue (mesophyll) where photosynthesis occurs and a vascular system that carries water and nutrients.
How did the ring form around the moon on new years?
Ice crystals formed out in outer-space forming an optical halo around the moon. It's actually more common than you think.
What is the different internal structure of stem?

What are your teeth coated with?
The outer layer of the tooth is the enamel, a material composed of calcium carbonate, magnesium carbonate, proteins, etc. Bacteria then form an outer biofilm around this called plaque, if not removed the plaque mineralizes forming what is called calculus or tartar.
How do nonmetals fill their outer shells when forming bonds with metal?
The positive and negative are attracted
