FC: Katelyn's Scrapbook on Plant Organelles | Per.7th | biology
1: Encloses the contents of the cell and serves as a semi-porous barrier to the outside environment. The plasma membrane is permeable to specific molecules. | Plasma Membrane
2: Mitochondria is considered to be the power generators of the cell, converting oxygen and nutrients into adenosine triphosphate. | Mitochondria
3: Golgi Apparatus | A Golgi Apparatus is typically comprised of a series of five to eight cup-shaped, membrane-covered sacs. | It modifies proteins and lipids that have been built in the endoplasmic reticulum and prepares them for export outside of the cell or for transport to other locations in the cell.
4: Photosynthesis occurs in almost all plant species and is carried out in specialized organelles known as chloroplasts. | Chloroplasts
5: Cytosol | Soup like substances where all the organelles stay in. Cytosol is mostly water but also contains protein.
6: Nuclear Membrane/Pore | The pores regulate the passage of molecules between the nucleus and cytoplasm, permitting some to pass through the membrane, but not others.
7: Nucleus | The nucleus is a highly specialized organelle that serves as the information processing and administrative center of the cell. This organelle has two major functions: it stores the cell's hereditary material, or DNA, and it coordinates the cell's activities, which include growth, intermediary metabolism, protein synthesis, and reproduction .
8: Ribosome | Ribosomes are tiny organelles composed of approximately 60 percent ribosomal RNA and 40 percent protein. These organelles serve as the protein production machinery for the cell.
9: Lysosome | The main function of these organelles is to serve as digestion compartments for cellular materials that have exceeded their lifetime or are otherwise no longer useful.
10: Cell Wall | The plant cell wall serves a variety of functions. Along with protecting the intracellular contents, the structure bestows rigidity to the plant, provides a porous medium for the circulation and distribution of water, minerals, and other nutrients, and houses specialized molecules that regulate growth and protect the plant from disease.
11: DNA | Deoxyribonucleic acid (DNA) is composed of genetic material. DNA is a nucleic acid present in the chromosomes of cells and many viruses. DNA is found in the nucleolus of a cell.
12: SmoothER | Smooth ER lack ribosomes. Its functions include lipid synthesis, carbohydrate metabolism, calcium concentration, drug detoxification, and attachment of receptors on cell membrane proteins.
13: Nucleolus | Nucleolus manufactures the subunits that combine to form ribosomes, the cell's protein-producing factories. Using types of RNA, along with telomeres and proteins, this organelle constructs both subunits of the ribosome.
14: Rough ER | The surface of the rough endoplasmic reticulum is studded with protein-manufacturing ribosomes giving it a "rough" appearance. Rough ER synthesize proteins.
15: Vacuole | vacuoles tend to be very large and are extremely important in providing structural support, as well as serving functions such as storage, waste disposal, protection, and growth.
16: Cytoskeleton | Cytoskeleton maintains cell shape, protects the cell, enables cellular motion, plays an important role in intracellular transport, and is very important in cell division.
