Vascular Bundles
They are found irregularly scattered in the ground tissue. Towards the periphery, the bundles are smaller in size while towards the centre, they are larger in size. The smaller bundles are younger, while the larger ones are older. Hence, the arrangement is described as centrifu..
Vascular bundles
Vascular bundles are radial in arrangement. There are eight bundles each of xylem and phloem. Hence, the condition is described as polyarch. Xylem is described as exarc..
Conjoint Bundle
In conjoint bundle xylem and phloem occur in the same bundle along the same radius. The conjoint bundle is of two types: Collateral where, the vascular bundle consists of only one set of xylem and one set of phloem. The collateral bundle..
Diagnostic Feature of an isobilateral leaf
Presence of two epidermal layers. Presence of cuticle and trichomes in both the layers. Amphistomatic condition. Presence of motor cells in the upper epidermis. Presence of undifferentiated mesophyll. Vascular bundles parallely arranged. Presence of a bu..
Diagnostic Features of a Monocot Stem

Anatomy of a typical Dorsi-Ventral Leaf
. These cells contain very few chloroplasts. Veins represent the vascular bundles. They are found irregularly scattered in the mesophyll due to reticulate venation. The largest and the oldest vein is found in the centre. It is known as midrib vei..

(PEP). PEP reacts with CO 2 to form oxaloacetic acid which is reduced by NADPH to form malic acid. The malic acid then reacts with RUBP to form pyruvic acid and PGA. The pyruvic acid is then phosphorylated by ATP to regenerate PEP while PGA is converted to triose phosphate as far as C 3 plants. The..

Tutor has given me a lot of good advise for my study. They has the package to be the best and the best teachers! they are not just have the teaching skills and understanding the subject matters as well. Thank you.
This tutor is a very good explainer, there is nothing wrong with the person. It just was slow and I understood alot so what i wanted took a very long time to get to. Nice person.
The tutor made sure i was learning and made sure i was paying attention, superbbbb session. Thank u
Terific helped showed how to apply formulas i will study these examples to go further--much gratitude--will come back again ThankYou
