Plant Cell is a basic block of the plant structure. The plant cell diagram below displays various parts of the cell including nucleus, cytoskeleton, cell wall, membrane, centrosome, central vacuole, chloroplast and others. Lets explain what each component is responsible for:
The nucleus is the commanding center of the cell controlling various functions of the cell and containing DNA. The nucleus is covered by the nuclear membrane. This is different from the cell membrane, which is a protein layer on the inside of the cell wall. The cell wall is a thick membrane that allows for passing of the nutrients and forms the structure of the plant together with other cells. The jelly material outside of the nucleus is called cytoplasm.
The key difference between plant cells and animals cells is the process of photosynthesis. Plant cells are able to convert sunlight, water and carbon dioxide into sugars (energy), oxygen and water. Photosynthesis takes place in the chloroplasts, which contains chlorophyll. Chlorophyll is a molecule responsible for this process and is usually green in color. The central vacuole stores sugars and water for cell’s use.
Plant cell diagram below lists various cell parts and explains some of their functionality.
Smiley Faces – Smiley icons – Smiley Symbols – Smiley Face Symbols – Smilies, smiles, emotions, emoticon and happy smile face icons. The classic image was originally developed in 1963 and included a yellow circle with two black dots for eyes and an arc representing the mouth. Yellow Smiley Symbols are widely used emoticons as signs of happy faces and one’s positive and other emotions.
Human heart is a key organ in the circulatory system responsible for pumping blood through blood vessels. The heart is found slightly to the left of the center of the chest. As shown in the below diagram, it consists of four chambers: left atrium, right atrium, left ventricle and right ventricle. Multiple valves found in the heart ensure that blood flows only one way through the heart. The lining of the heart consists of three layers: endocardium, myocardium and epicardium.
The blood low in oxygen flows into the right atrium from the superior and inferior vena cavae and further flows into the right ventricle. From here it is pumped into lungs where it releases carbon dioxide and absorbs oxygen. Blood high in oxygen content flows back to the left atrium and then passes through the left ventricle. It is then pumped out via the aorta. Aorta and other arteries transport blood away from the heart. The blood also carries nutrients and waste between the digestive system and various body organs.
The heart is essentially a muscle that contracts at a resting rate of ~72 beats per minute. The lower the heart rate when resting, the better for the health and individual’s longevity. The heart rate may increase during exercising. However, regular exercises ensure that the rate slows down in the longer term.
The heart diagram below lists key parts of the heart.

Eye Colors: the colors of a human eye are dependent on the two main characteristics. The first characteristic that determines eye color is the pigmentation of the eye’s iris, the second is the frequency of light scattering in the stroma of the iris. Iris varies from light brown to black, the blue and green pigments are not found in the human iris, rather these colours are a product of lighting conditions.
The eye colors are based on genetics: blue, grey, amber, hazel, brown, green, black. Blue, grey and green eyes are rare; most of world’s population has brown eyes. The eye color chart below depicts various types of eyes. Many now use contact lenses of different colours to alter their appearance.
Cell diagram: Human cell as most other animal cells make up the structure of the body. Cell diagram below is representative of a typical human cell responsible for carrying out various bodily functions and processing nutrients into energy used to sustain itself. The diagram shows the following elements: nucleus, membrane, ribosomes, lysosome, cytoplasm and others. Now lets explain what each of the cell parts is responsible for.
Cytoplasm is a part of the cell filled with cytosol liquid surrounding the nucleus. The nucleus is the center of the cell and acts as its control unit responsible for cell growth, division and maturity. Nuclear envelope is the membrane that surrounds the nucleus protecting the DNA from the rest of the cell.
The outside of the cell is protected by the plasma membrane. This membrane allows for passing of the nutrients and waste. An organ that ensures energy from nutrients can be consumed by the cell is called Mitochondria. The Golgi apparatus ensures molecules processed by the endoplasmic reticulum can be passed through the cell.
Peroxisomes and Lysosomes are responsible fore recycling of the worn-out cell parts while also breaking down bacteria and toxins. The cell diagram below lists various cell parts.
