List of all cell features and functions:
• Nucleus
• Cytoplasm
• Cell membrane
• Mitochondria
• Ribosomes
• Cell wall (Plant Cell)
• Endoplasmic Reticulum (smooth & rough)
• Lysosome
• Golgi Apparatus/body
• Nucleolus
• Vesicles
A nucleus is like the brain of the cell, it is a large oval which controls the activities of the cell and the nucleus also contains genetic material (DNA). The nucleus also contains hereditary information.

Most chemical processes and reactions, which are controlled by enzymes, occur in the Cytoplasm. It also supports and protects the organelles. The Cytoplasm is a cytosol, a jellylike material and it is also clear and thick. It also holds the cytoskeleton fibres.

A cell membrane controls what substances

They are made up of different types of nerve cells, which all have an axon which is a long stem-like part of the cell which relays potential signals to the following cell. It organises and controls many of the body’s activities. It also helps to stimulate muscle contraction, makes the body aware of its surroundings and environment. It helps with emotion and memory. The cells in the nervous tissues need to be able to communicate with each other by using electrical nerve impulses. The functions of the nervous system are:
• Sensory input
• Integration
• Control of muscles
• Control of glands
• Homeostasis
• Mental activities

Extra information on muscle tissues:
Muscle tissues like the skeletal muscle tissue are often referred to as striated because of its’ exterior, which are made up of dark and light bands that can only be seen through a microscope. A single skeletal muscle cell is long and shaped like a cylinder and it also has many nuclei positioned around the circumference of the cylinder. The cells are long and slim and are known as muscle fibres and most of the time are ordered in layers and are surrounded by connective tissue.

Extra information on connective tissues:
Connective tissues

    Throughout the inside of the nucleus, is a substance called the nucleoplasm, which suspends the nucleus’ structures. The nucleus controls the activities of the cell to maintain life and reproduce. It also regulates the synthesis of protein by sending mRNA to the ribosomes of the cell as a template for protein production. The nucleus contains the genetic material of the cell, deoxyribonucleic acid, or DNA, which is…

    Rough endoplasmic has a surface dotted with proteins and the smooth endoplasmic is made up of tubules which increases surface area. They insure there is more surface area for cell reactions. Also involved in making nuclear membranes during the division of cells. Carbohydrates and proteins are transported to different organelles including lysosomes and plasma membrane. Golgi body- they are only found in eukaryotic cells.…

    These parts are called organelles and every animal cell contains them, like how every living thing contains cells. The nucleus is the main control point of the cell which commands all organelles. The cell membrane is the guard of the cell which is selectively permeable. The cytoplasm surrounds all organelles in the cell and in combination with the cell membrane, provide the cell the structure. The mitochondria provide the cell with power while the vacuoles stores nutrients for the cell.…

    The mammalian nervous system consists of highly specialised cells called neurons, alongside supporting cells. The human brain contains 1010 to 1012 neurons (1). Neurons have a distinct cell shape and range from microns up to a millimeter in length. Neurons’ unique structure allows for rapid and specific transmission of signals along a neuron, and from one neuron to another. Neurons transmit nerve impulses over long and thin axons, and receive information through branches of dendrites.…

    We also have what is known as intracellular organelles which, as per the name, means within the cell. Intracellular organelles include the nucleus, as I discussed previously, is the center of the cell and is the largest organelle and plays the most important biological role. The nucleus of the cell is packaged into what we know as chromosomes. Chromosomes contain DNA and proteins that carry all the genetic information of an organism. The nucleus is also the site for DNA and RNA synthesis.…

    The inner membrane is folded inside to form cristae, which are folded into the matrix. Mitochondria are the organelles of cellular respiration in nearly all cells. Chemical energy called adenosine triphosphate (ATP) is produced by harvesting energy from sugars and other food molecules. Molecules of ATP are used by cells as a direct source of energy for most of their work. Mitochondria and chloroplasts have the ability to provide cellular energy and they contain their own DNA that encodes some of the own proteins.…

    Neurons have the metabolic machinery characteristics to somatic cells of other types. They have a nucleus and all other organs that are needed for a normal cellular life. Neurons are characterized by specialization in intracellular communication. Neurons in the matured CNS involves a secretion of special chemical molecules called neurotransmitters. Neuroglia provide a variety of functions for brain tissue and support the metabolic and signaling functions of the neurons.…

    The inner membrane surrounds the stroma and grana other words known as stacks of thylakoids (NCBI, 2016). Endoplasmic reticulum: Its main function is translation and folding of new proteins across the ER membrane. Its structure is made up of a single membrane system (BSCB, 2016). There are 2 types of endoplasmic reticulum rough endoplasmic and smooth. They appear to be separate however they are sub compartments of the…

    The reticular coating has an erratically connective tissue, blood vessels, different glands, and lamellar corpuscles. On the other hand, the dermis layer is strong because of the collagen fibers all over the dermis. The blood vessels that are a part of the dermis is what preserves the homeostasis in the body temperature. C. Hypodermis- This subcutaneous tissue is near the dermis and holds adipose tissue. The hypodermis is not involved with the skin, but the tissue gives a way to store…

    ER is made of two different types, smooth and rough. Centrosomes are also present and they contain important spindle fibers which develop during the process of cell division. Main Functions: Endoplasmic Reticulum- a network of tubular membranes within the cytoplasm of the cell, occurring either with a smooth surface (smooth endoplasmic reticulum) or studded with ribosomes (rough endoplasmic reticulum) involved in the transport of materials. Nucleus- a dense organelle present in most eukaryotic cells, typically a single rounded structure bounded by a double membrane, containing the genetic material (Contains: nuclear pore, nucleolus, nucleoplasm, and nuclear envelope) Golgi Apparatus- a complex of vesicles and folded membranes within the cytoplasm of most eukaryotic cells, involved in secretion and intracellular…
