Animal Cell - Structure, Function, Diagram and Types
We are aware of the fact that the cell animal cell essay the structural and fundamental unit of life. It is also the smallest and the most basic biological unit of living organisms. On the basis of animal cell essay cellular organization, animal cell essay, cells are further classified as eukaryotic and prokaryotic. Plant cells and animal cells fall under the eukaryotic category. Let us have a detailed overview of the animal cell, its types, diagram and structure, animal cell essay. Animal cells range in size from a few microscopic microns to a few millimetres. The largest known animal cell is the ostrich egg, which can stretch over 5.
This is in stark contrast to the neuron in the human body, which is just microns across. The shape of animal cells also varies, with some being flat, others oval or rod-shaped. There are also more intriguing shapes such as curved, spherical, animal cell essay, concave and rectangular. Most of the cells are microscopic in size and can only animal cell essay seen under the microscope. As stated before, animal cells are animal cell essay cells with a membrane-bound nucleus. Furthermore, these cells exhibit the presence of DNA inside the nucleus. They also comprise other membrane-bound organelles and cellular structures which carry out specific functions necessary for a cell to function properly, animal cell essay.
The diagram given below depicts the structural organization of the animal cell. The various cell organelles present in an animal cell are clearly marked in the animal cell diagram provided below. Animal cell diagram detailing the various organelles. Though this animal cell diagram is not representative of any one particular type of cell, animal cell essay, it provides insight into the primary organelles and the intricate internal structure of most animal cells. Furthermore, it is easy to distinguish between a plant and animal cell diagram just by inspecting the presence or absence of a cell wall. Animal cells are generally smaller than plant cells.
Another defining characteristic is its irregular shape. Animal cell essay is due to the absence of a cell wall. But animal cells share other cellular organelles with plant cells as both have evolved from eukaryotic cells. A thin semipermeable membrane layer of lipids and proteins surrounding the cell. Its primary role is to protect the cell from its surrounding, animal cell essay. Also, it controls the entry and exit of nutrients and other microscopic entities into the cell. For this reason, cell membranes are known as semi-permeable or selectively permeable membranes, animal cell essay. It is an organelle that contains several other animal cell essay such as nucleolus, nucleosomes and chromatins, animal cell essay. It also contains DNA and other genetic materials.
It is a double-membrane structure that surrounds the nucleus. It is also referred to as the nuclear envelope. It is a small organelle found near the nucleus, which has a thick centre with radiating tubules. The centrosomes are where microtubules are produced. They are round organelles surrounded by a membrane and comprising digestive enzymes which help in digestion, excretion and in the cell renewal process. A jelly-like material which contains all the cell organelles, enclosed within the cell membrane. The substance found within the cell nucleus, contained by the nuclear membrane is called the nucleoplasm. A flat, smooth layered, sac-like organelle which is located near the nucleus and involved in manufacturing, storing, packing and transporting the particles throughout the cell. Detailed Reading: Golgi Apparatus.
They are spherical or rod-shaped organelles with a double membrane. They are the powerhouse of a cell as they play an important role in releasing energy. They are small organelles made up of RNA-rich cytoplasmic granules, and they are the sites of protein synthesis. This cellular organelle is composed of a thin, winding network of membranous sacs originating from the nucleus. A membrane-bound organelle present inside a cell involved in maintaining shape and storing water, food, wastes, etc. They animal cell essay tiny holes present in the nuclear membrane which are involved in the movement of nucleic acids and proteins across the nuclear membrane.
There are numerous types of animal cells, animal cell essay, each designed to serve specific functions. The most common types of animal cells are:. Melanocytes, keratinocytes, Merkel cells and Animal cell essay cells. The cell is the structural and functional unit of life. These cells differ in their shapes, sizes and their structure as they have to fulfil specific functions. Plant cells and animal cells share some common features as both are eukaryotic cells. However, they differ as animals need to adapt to a more active and non-sedentary lifestyle. Furthermore, animals need to acquire their own food, therefore, they do not possess any of the specialized cell organelles such as chloroplasts. Animal Cell is a fundamental topic taught in class 9 and higher.
As the name implies, an animal cell is a type of cell that is seen specifically in animal tissues. It is characterized by the absence of a cell wall, with cell organelles enclosed within the cell membrane. An animal cell is usually irregular and round in shape. This is primarily due to the absence of the cell wall, which is a characteristic feature of plant cells. Furthermore, animal cells do not have plastids as animals are not autotrophs. Put your understanding of this concept to test by answering a few MCQs. hi, may I say your calculations and reasoning is wrong animal cells are generally smaller than plant cells?
In humans, the body releases hormones such as adrenaline and cortisol during times of stress or anger. These hormones are called stress hormones. Great I think I have fallen love with the byjusAfter seeing this detailed notes of animal cells. Are the cells of grooved brain corals diploria labyrinthiformis any different from normal animal cells? Grooved brain corals are marine invertebrates, hence, they share common characteristic features with animal cells. However, these organisms have symbiotic algae living within their cells, providing energy from photosynthesis.
Why spontaneous generation was previously considered as a plausible explanation on how life animal cell essay originate from an organic matter? Many toxins work by hindering specific functions of the animal cell essay. For instance, cyanide disrupts the mitochondrial electron transport chain within cells — rendering the body unable to derive energy. Prokaryotic organisms are always unicellular. Regardless, they are not classified as multicellular. Hahaha this animal cell discovered by theodor schwann and i think animal cells are related in the abiogenesis theory because cells are come from all living things. In sentences, differentiate the sebaceous from sweat glands in terms of structure, distribution, function, and secretion.
If the organisation of a cell is destroyed due to some physical or chemical influence, what will happen? Cells dying in large numbers are never good for the body. For example, if a pathogen enters the body and starts producing toxins that destroy the red blood cells, then the number of RBCs to transport oxygen decreases. This can then hamper other vital functions of the body. Cells are the basic unit of life because all living organisms animal cell essay made up of cells. Cells are the structural and functional unit of life. Most plants and animals cells are very small in size, around µm, hence, cannot be seen with the naked eye.
No, paramecium is a unicellular, cilliated protozoan and is heterotroph. It belongs to the kingdom Protista. ATP was discovered by Karl Lohmann. The role of ATP in energy metabolism was discovered by Fritz Albert Lipmann. Your Mobile number and Email id will not be published, animal cell essay. Request OTP on Voice Call. Post Comment.
