Answer #1

Anther is the male reproductive organ of an angiosperm. It is present in flowers. It is a part of androecium or stamen. It is a bilobed tetrasporangiate structure which contains the microspore mother cell. These are diploid cells which undergo meiosis to form pollen grains.

There will be pairs of chromosome present in cells inside anther. These cells will be undergoing meiosis to form pollen grains.

Experiment 3: The Importance of Cell Cycle Control Some environmental factors can cause genetic mutations that result in a lack of proper cell cycle control (mitosis). When this happens, the possibility for uncontrolled cell growth occurs. In some instances, uncontrolled growth can lead to tumors, which are often associated with cancer, or other biological diseases. In this experiment, you will review some of the karyotypic differences that can be observed when comparing normal, controlled cell growth and abnormal, uncontrolled cell...
