Haploid and diploid are terms in cell division. The term ploidy refers to the number of chromosomes present in the nucleus of a cell. Haploid cells are cells that have just one set chromosome present in them. They are produced through the process of meiosis. The most common example of haploid cells is the germ cell which this also known as the sex cell. Organisms such as algae also have haploid cells at some point in their life cycle.
Diploid cells are cells that have two sets of chromosomes present in their nucleus. A common example is humans. Somatic cells in humans have 2 sets of chromosomes. Every one of us has two sets of the chromosome with one set from each parent. Normally, a person gets 23 chromosomes from the father and 23 chromosomes from the mother. However, in some chromosomal disorders, these numbers are altered. Hope you find this information helpful.
Many scientists use microscopes, but sometimes a compound microscope is needed. This type of microscope is different because it includes two lenses. The compound microscope is a type of optical microscope and it has an eyepiece lens and an objective lens. It is believed that this microscope uses more light to help pass it through to the object trying to be seen.
Types of compound microscopes include stereo microscope, comparison microscope, inverted microscope and traveling microscope. One difference between a compound microscope and a regular microscope is that a regular microscope has a convex lens whereas the objective lens is located away from the eyepiece lens and is next to the object so more light will be used to see the object.
Cells are the smallest unit in biology. Everyone has cells and there are many of them inside of someone’s body. There are two main types: animal cells and plant cells. These are called the eukaryote and prokaryote. They look different and have a different make-up. If you look inside of each of those cells, they will look different and have different things in them.
For instance, an animal cell has a nucleus in the middle, but a plant cell does not. Animal cells or Eukaryote cells are inside of humans. Other parts of cells include the cell membranes and nucleic acids. For both types of cells, they are the basic unit of life. They also come from pre-existing cells and all living things like animals and plants are made up of cells.
Protoplasm is the entire content of a cell, and it contains both the nucleus and the cytoplasm. This shows that there is no big difference between cytoplasm and protoplasm. The cytoplasm is not a separate entity; it is part of the protoplasm. Protoplasm and cytoplasm are semi-fluid substances, and each has its own contents. While the protoplasm consists of cytoplasm, cell membrane, and the nucleus, the cytoplasm consists of organelles, vesicles, and cytosol. In other words, cytoplasm refers to the contents of a cell without the nucleus.
The cytosol in the cytoplasm consists of salts, water, and other organic materials, and the organelles in the cytoplasm consist of mitochondria, endoplasmic reticulum, Golgi body, ribosomes, etc. The ribosome is the site for protein synthesis. Protoplasm can be described as the living matter of animal cells. There are different types of processes that occur in the protoplasm, and the functionality of the whole body depends on those processes.

The most apparent difference between an egg cell and a sperm cell is that sperm is a reproductive cell from a male while the egg cells are from females. Both egg and sperm cells depend on each other for the reproduction of human life, and they both undergo meiosis. There is a difference in the formation time for both egg and sperm cells. The raw materials for egg cell production are formed while the fetus is still in the uterus.
Every baby girl is born into a world with about 4 million egg cells in her ovaries. These eggs drop into the uterus once every month once she is at the age of sexual maturity. On the other hand, sperm cells are produced continuously. They die, but they also are replenished, and this process usually takes about three weeks. When the sperm cell completes its second lifecycle, it is done, and it cannot develop any further.
Meanwhile, once the egg drops into the uterus, it is halfway through the first and second stage of the lifecycle. It does not complete until sperm comes to fertilize it. The hormones are different, as testosterone is the essential hormone that is responsible for the production of sperm cells, estrogen is the female hormone that promotes the release of luteinizing hormone, which triggers the egg cell released from the ovary.
According to the Cell Theory, cells are called the building blocks of life because each and every living organisms are made up of cells. And cells are the basic and structural unit of life. These cells come from other primitive cells.

This is also known as the endoplasmic reticulum. This type of organelle is usually found in eukaryotic cells. This normally works with the Golgi Apparatus and the other parts of the eukaryotic cells. This is responsible for the transportation of the carbohydrates, proteins, and other organelles. This is also very effective for the formation of the skeletal framework.
The endoplasmic reticulum will also synthesize the various hormones from the cholesterol. This will also be the place where protein folding and modification may take place. Take note that there are different types of endoplasmic reticulum such as the rough and smooth ER. They have different functions from each other.
