Answer:
The chromosomes become visible under a light microscope during prophase stage of mitosis
Explanation:
Propohase -
The first phase of mitosis , in which the chromosomes becomes visible , as a distinct structure , the nuclear envelope breaks down and the spindle formation takes place .
Hence , this stage is visible under the light microscope.
The next phase is the metaphase , in which the chromosomes line up in middle of cell .
In the third phase , i.e. , the anaphase , the chromosomes moves towards the opposite sides of the vcell .
In the fourth phase , i.e. , the telophase , the two nuclei are formed .
In the last stage , i.e. , cytokinesis , the cell finally divides into two daughter cells .
Answer:
Sexual reproduction just means combining genetic material from two parents. Asexual reproduction produces offspring genetically identical to the one parent.
Cell membranes are important because they protect the cell and control the materials that flow in and out of it. Lipids are needed in order to create the membranes in the cell.
The cell membrane is semipermeable (or selectively permeable). It is made of a phospholipid bilayer, along with other various lipids, proteins, and carbohydrates.
Answer:
Plants produce oxygen gas and glucose molecule during the process of photosynthesis by absorbing radiation of the sun.
Explanation:
Photosynthesis is a process in which glucose and oxygen are produced by the combination of carbondioxide and water in the presence of sunlight. Carbondioxode is taken in the leaves through stomata and water is absorbed by the plant from the soil. When these two substances combine in the presence of sunlight produces glucose and oxygen.
