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 …show more content…
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.
