ORGANELLE
DIAGRAM FORM FUNCTION
Nucleolus
• The nucleolus is a darker staining region of the nucleus. It is non-membrane bound structure composed of ribonucleic acids (RNA) and proteins. It makes ribosomes inside the nucleus and contains all the DNA of the cell. It is also used for cellular reproduction and it is often referred to as the brain of the cell as it controls what goes on.
Golgi apparatus
A group of fluid-filled flattened membrane bound sacs located close to the nucleus. Vesicles are regularly seen at the sacs' edges. It is stack of layer bound, flattened sacs, which gets protein from the ER and adjusts them.
Golgi apparatus …show more content…
A membrane surrounds the lysosomes and it keeps the enzymes enclosed within it. Lysosomes contain powerful digestive enzymes, which helps to break down the material e.g. white blood cells.
Ribosomes 3) Ribosomes are non-membrane- bounded particles that float free in the cytoplasm or it is usually attached to the rough endoplasmic reticulum (ER). It is made of RNA, protein and is site for protein synthesis.
Vesicles Vacuole is a small fluid filled sac present in the cytoplasm and it is always surrounded by a membrane. It transports substance in and out of the cell through plasma membrane. Some vacuoles are formed by Golgi apparatus and ER, while others are formed at the cell surface.
Cytoplasm
The Cytoplasm is a jelly- like liquid present in a cell. It is a colourless substance and generally alluded as cytosol (means substance of the cell). It encompasses the cell membrane, nucleus and cellular organelles.1 Its main function is the movement of cellular organelles inside the cell. It also provides shape to the cell.
Nucleus
Large organelle encompassed by a nuclear envelope. Winch has pores. The nucleus is made up of chromatins and DNA. Control all the activities performed by the …show more content…
These tissues produce neurotransmitters. It is specialised to respond to stimuli and to conduct impulses to different organs in the body. Nerve tissues are all composed of a particular nerve cell called neurons. It has three types’ neurones, which are sensory neuron, motor neuron and inter neurons. It conducts impulses to and from body organs via neurons. They are located in the brain, spinal cord and nerves. They help transmit electrical impulses from the brain to whatever is left the rest of the body forward and backward. They are wide and star-like and have legs that can spread starting with one place to another. It contains one nucleus that is found right in the
