FC: MIxbook of cells by: Brian Swet Aaron Makselan
1: The first person who ever discovered the cell and used the term cell was Robert Hooke. Although he was not the first to view these tiny unicellular organism Antonie Van Leeuwenhoek.
2: The nucleus contains most of the cell's genetic information. The nucleus is an enclosed membrane in the eukaryotic cell. Its the control center of the cell.
3: mitochondria is a membrane-enclosed organelle found in most eukaryotic cells. Its job is to supply energy through the generatation most of the cell's supply of adenosine triphosphate
4: DNA is a nucleic acid that contains the genetic instructions used in the development and functioning of all known living organisms with the exception of some viruses. The main role of DNA molecules is the long-term storage of information.
5: chromosome is an organized structure of DNA and protein that is found in cells. It is a single piece of coiled DNA containing many genes, regulatory elements and other nucleotide sequences. Chromosomes also contain DNA-bound proteins, which serve to package the DNA and control its functions.
6: cell membrane is a biological membrane that separates the interior of all cells from the outside environment. The cell membrane is selectively-permeable to ions and organic molecules and controls the movement of substances in and out of cells.
7: cell wall is the tough, usually flexible but sometimes fairly rigid layer that surrounds some types of cells. It is located outside the cell membrane and provides these cells with structural support and protection, and also acts as a filtering mechanism. It is found in a plant cell
8: flagella is a tail-like projection that protrudes from the cell body of certain prokaryotic and eukaryotic cells, and functions in locomotion.
9: cilia is an organelle found in eukaryotic cells. Cilia are slender protuberances that project from the much larger cell body.There are two types of cilia: motile cilia and non-motile, or primary cilia, which typically serve as sensory organelles.
10: chloroplast are organelles found in plant cells and other eukaryotic organisms that conduct photosynthesis. Chloroplasts capture light energy. They are responsible for the plants color of green.
11: centrioles is a barrel-shaped cell structure found in most animal eukaryotic cells, though absent in higher plants and most fungi.
12: endoplasmic reticulum is an eukaryotic organelle that forms an interconnected network of tubules, vesicles, and cisternae within cells. Rough endoplasmic reticulua synthesize proteins, while smooth endoplasmic reticulua synthesize lipids and steroids, metabolize carbohydrates and steroids, and regulate calcium concentration, drug detoxification, and attachment of receptors on cell membrane proteins. Sarcoplasmic reticulua solely regulate calcium levels.
13: vacuole is a membrane bound organelle which is present in all plant and fungal cells and some protist, animal and bacterial cells.
14: cytoskeleton is a cellular skeleton" contained within the cytoplasm and is made out of protein. The cytoskeleton is present in all cells; it was once thought to be unique to eukaryotes
15: cytoplasm whrere all contents of the cells of prokaryote organisms (which lack a cell nucleus) are contained within the cytoplasm. Within the cells of eukaryote organisms the contents of the cell nucleus are separated from the cytoplasm, and are there called the nucleoplasm.
16: lysosome are cellular organelles which contain acid hydrolase enzymes to break up waste materials and cellular debris. Lysosomes digest old or worn out organelles in a cell.
17: golgi apparatus is an organelle found in most eukaryotic cells. The primary function of the Golgi apparatus is to process and package macromolecules, such as proteins and lipids, after their synthesis and before they make their way to their destination; it is particularly important in the processing of proteins for secretion. The Golgi apparatus forms a part of the cellular endomembrane system.
18: ribosomes are the components of cells that make proteins from all amino acids. One of the central tenets of biology, often referred to as the "central dogma," is that DNA is used to make RNA, which, in turn, is used to make protein.
19: Similarities between plant and animal cells: Both are Eukaryotic Cells. Every cell has a nucleus and chromosomes DNA Cytoplasm
20: This is an Animal Cell. The main differences between a plant cell and and animal cell are that plant cells have... A cell wall and Chloroplasts. *
21: Here is a plant cell.
