Cells and Tissues
Here you can find all the information and products involving Cells and Tissues!
The cell is the most basic functional unit of life forms, though aspects may vary greatly, at their most basic form, they contain a cytoplasm enclosed within a membrane as well as biomolecules such as DNA (deoxyribose nucleic acid), RNA (ribonucleic acid) as well as other proteins. Tissues are a biological organisation of these cells to form a complete organ that can carry out a range of functions. Without these incredibly complex building blocks, life would not exist and with an estimated 37 trillion cells in the human body, research on this topic is invaluable as we strive to have a greater understanding of these intricate components.
Table 1 - Differences between Prokaryotes and Eukaryotes
Prokaryotes | Eukaryotes | |
Typical Organisms | Bacteria, Archaea | Protists, Fungi, Plants, Animals |
Typical Size | 1-5μm | 10-100μm |
Type of nucleus | Nucleoid region; no true nucleus | True nucleus with double membrane |
DNA | Often circular | Linear molecules (chromosomes) with histone proteins |
Ribosomes | 50S and 30S | 60S and 40S |
Cytoplasmic structure | Very few structures | Highly structured by endomembranes and a cytoskeleton |
Cell Movement | Flagella made of flagellin | Flagella and cilia containing microtubules; lamellipodia and a cytoskeleton |
Mitochondria | None | One to several thousand |
Chloroplasts | None | Present in algae and plants |
Organization | Often single cells | Single cells, colonies, higher multicellular organisms with specialized cells |
Cell division | Binary fission (simple division) | Mitosis (fission or budding) Meiosis |
Chromosomes | Single chromosome | Many chromosomes |
Cells can be broken into 2 groups, these are prokaryotic, containing a nucleus and eukaryotic, not containing a nucleus, this is detailed in figure 1. The most discernible difference is the presence of compartmentalisation, or more simply put, the presence of membrane bound organelles since these are only present in eukaryotic cells. Organelles are small, complex structures within the cell that carry out a range of processes that vary depending on the cell, but all eukaryotes contain a DNA nucleus that maintains all cell activity, a cell membrane that protects the cell by providing separation between the outside of the cell and the organelles within and the cell membrane, and the cytoplasm, the area within the cell membrane where organelles are located.
Eukaryotic cells covers plants, animals, fungi, protozoa, algae and slime moulds. They are generally much larger than their nucleus lacking counterparts ranging between 10-100μm whereas procaryotes typically fall between the 1-5μm range. Eukaryotes additionally contain a true (surrounded by a membrane) nucleus, containing the bulk of genome as well as carrying out RNA transcription. Please see table 1 for a general comparison of these two types of cells.
Similar to cells, there are an incredible number of tissues that both animals and plants utilise to take advantage of the surrounding environment and available energy to carry out a process. One of the most noteworthy of these functions is photosynthesis in plants, this is carried out by an organ, such as leaves, of which the palisade layer, the tissue contains a large quantity of chloroplasts which carry out the function, converting sunlight into chemical energy. This concept applies to animals, though with an extensive number of facets that come into play to extract nutrients and energy from the
An example of this is in animal epithelial tissue which not only have a range of functions including elimination of waste and lining of cell free surfaces and also multiple classifications of epithelial cell including transitional epithelium, cuboidal epithelium and columnar epithelium.
