Cell Quizzes Online & Trivia

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.

The correct order of a typical reflex arc is shown below: Sensory Receptor: A typical reflex starts with a sensory receptor to receive stimulus from the outside world to initiate the impulse in a sensory neuron. Sensory Neuron: It receives the impulse from the receptor and sends it to intermediary neuron. Intermediary Neuron: It carries information towards a motor neuron by communicating with the brain. A Motor Neuron: It sends messages either to the muscle or gland. The Effector: It is the last process of a typical reflex arc which reacts by contracting.  

Cell wallThe centriole is ONLY in animal cells. It helps in cell division. The nucleus is found in all Eukaryotic cells. Plants and animals are eukaryotic. The plasma membrane is found in all cells.

Cell membrane , cell wall ,nucleus, cytoplasm, chloroplast by isobel wright

1. NucleusProkaryotic cell, by definition, is a cell WITH OUT a nucleus. Example: Bacteria. Prokaryotic cells will ALL contain cell membrane and cytoplasm. In addition bacteria do have cell walls.

The correct answer is not listed in the answers. It’s 32 cells total. It’s not a lot, but that is a lot for the small amount of time that five divisions would take. Six cell divisions would get you the final answer - 64 cells total. When a cell divides, it becomes two cells. First, the DNA replicates. Then, the cell organelles duplicate, and the cell swells as the cytoplasm increases too. The final thing to happen is the cell membrane grows between the old organelles and the new ones. Once that’s done, the two cells separate as much as they can, and voila. They have two cells where there had been one. The cycle starts again, and continues indefinitely in some 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.

Which part of the cell is responsible for breaking down and essentially “digesting” substances?

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.

True because active transport requires energy to take place while diffusion doesn't require energy

It would be A: Ribosomes because its made out of small structures. amio acids are assembled to make protiens. Which is why its given the nickname "Protien factory". But is found in both animal and cell.

The answer to this is letter A. What are prokaryotic cells anyway? Prokaryotes are known to be organisms that are unicellular. This means that they do not have organelles. They also do not have internal membrane-bound structures. They just have one chromosome that is located in the nucleoid. It should be remembered that bacteria is a prime example of a prokaryote. For instance, E.Coli that is well known for causing diarrhea is a prokaryote. The main difference of a prokaryote with a eukaryote is the eukaryote comes with a nucleus while the prokaryote does not have a nucleus. It is obvious that their overall structures are different too.
