if you are provided with microscopic preparation of transverse
section of a meristematic tissue and permanent tissue, how would
you distinguish them?
meristematic
tissues
permanent tissues


1 meristematic tissues have the capacity
to divide
1 permanent tissues do not have the
capacity to divide


2 they have thin cellulose wall and do
not have intercellular spaces
2 they have thick cellulose wall and they
do have closely packed or small intercellular spaces


3 they contain dense cytoplasm with
prominent nucleus
3 they contain thin cytoplasm with normal
nucleus


4 they contain many small vacuoles in
their cytoplasm
4 they contain a single large vacuole in
their cytoplasm
different cells in the body have different instructions or marching orders as to how they are to grow and function. sometimes clumps of cells with diverse marching orders form a tumor and mature into very different types of tissue. one type is called a dermoid cyst. these can contain a variety of different tissues including hair. see more... two pink colored flowers on crossing resulted in 1 red, 2 pink and 1 white flower progeny. the nature of the cross will be cross fertilization. cross fertilization is transfer of pollen grains from one plant to the stigma of flower borne of different plant of same species. a) the megasporogenesis occurs in the nucellus (towards the micropylar end).

the process of formation of megaspores from the megaspore mother cell is called megasporogenesis. ovules generally differentiate a single megaspore mother cell (mmc) in the micropylar region. of the nucellus. it is a large cell containing dense cytoplasm and a prominent nucleus. the mmc undergoes meiotic division. meiosis results in the production of four megaspores. in a majority of flowering plants, one of the megaspores is functional while the other three degenerate.

b)



the three celled male gametophytes has one vegetative cell and two male gametes and no generative cell. Good morning, thanks for asking at HealthReplies.com. Tracheostomy is one of the health procedures performed to overcome problems in the respiratory system. This procedure is done by forming a hole as another way for air to get in and out because the normal respiratory path does not allow for the process of breathing normally.



  

After the extraction, it is normal for the hole formed by this procedure to close by itself and no sewing is carried out because it can actually lead to other complications. As long as it has not closed naturally, the hole will be minimally covered by gauze to ensure no impurities will enter.



  

As for your case, with a fairly long time span, our advice should you go back to the doctor who used to handle you to see firsthand the condition, what if the cause of your recovery is hampered. It should be seen if you have diabetes or other medical conditions that must be treated first so that the hole can close. If in the end it cannot close, other treatments will be considered more permanent in your case. If for one reason or another you cannot see the same doctor, at least look for another surgeon in the same hospital, or at least a fellow surgeon. In essence, the conditions that you experience will be treated differently depending on your current situation, and it really requires a direct examination by a competent doctor. So, hopefully answering your question. it is wonderful that you have been able to get past the drugs & each day forward will help your system rebuild. some tissues that are irritated or injured by the exposure will repair over weeks, months & years but some effects are lasting. the central nervous system, nerves & heart muscle have little ability to repair if affected. see more... if you're really concerned for a stroke or tia - you might want to discuss s mri with and without contrast as well as an mra. hope that helps! vertical and horizontal no. reticulate venation parallel venation 1. in reticulate venation, veins and veinlets form a network. in parallel venation, veins run almost parallel to one another. 2. it is found in dicotyledonous plants. it is found in monocotyledonous plants. 3. e.g. mango, peepal, etc. e.g. banana, grasses, etc. the nerves would be different for the hands and feet. see more... a uterine septum is a form of a congenital malformation where the uterine cavity is partitioned by a longitudinal septum; the outside of the uterus has a normal typical shape. for report ask ur pathologist
