- The plastid (Greek: πλαστός; plastós: formed, molded – plural plastids) is a major double-membrane organelle found in the cells of plants, algae, and some other eukaryotic organisms. Plastids were discovered and named by Ernst Haeckel, but A. F. W. Schimper was the first to grant them a clear definition. Plastids are the site of manufacture and storage of important chemical compounds used by the cell.

- Thylakoids (Menke,1961) are membrane lined flattened sacs which run throughout the stroma or matrix of the chloroplast. The word thylakoid come via Latin from Greek thylakos meaning sac or pouch. Thus, thylakoid means sac-like or pouch-like. Since, they take part in photosynthesis, they are also called photosynthetic thylakoids. They are thus the structural elements of the chloroplast.

Definitions &Translations Lipids are a group of naturally occurring molecules that include fats, waxes, sterols, fat-soluble vitamins (such as vitamins A, D, E, and K), monoglycerides, diglycerides, triglycerides, phospholipids, and others.ipids may be broadly defined as hydrophobic or amphiphilic small molecules; the amphiphilic nature of some lipids allows them to form structures such as vesicles, multilamellar/ unilamellar liposomes, or membranes in an aqueous environment.

Chloroplast Function in Photosynthesis A chloroplast is a type of plant cell organelle known as a plastid. Plastids assist in storing and harvesting needed substances for energy production. A chloroplast contains a green pigment called chlorophyll, which absorbs light energy for photosynthesis.Hence, the name chloroplast indicates that these structures are chlorophyll containing plastids.Like mitochondria, chloroplasts have their own DNA, are responsible for energy production, and reproduce independently from the rest of the cell through a division process similar to bacterial binary fission. chloroplast contains a green pigment called chlorophyll, which absorbs light energy for photosynthesis. Hence, the name chloroplast indicates that these structures are chlorophyll containing plastids.

Plant Cell Plastids are cell organelles that store specific things found only in plant cell but absent in animal cells. In plant cell they are found in the cytoplasm. Plastids are spherical or ovoid in shape. They are involved in manufacture and storage of certain important chemical compounds.

What are Lipids? What are Lipids? Lipids are molecules that contain hydrocarbons and make up the building blocks of the structure and function of living cells. Examples of lipids include fats, oils, waxes, certain vitamins, hormones and most of the non-protein membrane of cells. Lipids are not soluble in water.

Definitions &Translations Chloroplasts are organelles found in plant cells and some other eukaryotic organisms. As well as conducting photosynthesis, they carry out almost all fatty acid synthesis in plants, and are involved in a plant's immune response. A chloroplast is a type of plastid which specializes in photosynthesis.

- The Apicomplexa (also called Apicomplexia) are a large phylum of parasitic protists. Most of them possess a unique form of organelle that comprises a type of plastid called an apicoplast, and an apical complex structure. The organelle is an adaptation that the organism applies in penetration of a host cell.

Lipids - Definition and Examples Lipid Definition. Lipids are class of naturally-occurring organic compounds that you may know by their common names: fats and oils. A key characteristic of this group of compounds is that they are not soluble in water. Here's a look at the function, structure, and physical properties of lipids.

- Chloroplasts is a major organelle. The green pigments that make plants green. They are often called plastids, though plastids and chloroplasts are not exactly the same thing—a chloroplast is a special kind of plastid that photosynthesizes. Chloroplasts do lots of things, but their main function is photosynthesis.

- Very few animals can synthesize carotenoids, but, when ingested, these pigments do affect the color of various animal tissues such as egg yolk and body fat, lending them yellow and orange colorations. Note: The word chromoplast is sometimes used to refer to any pigmented plastid, even a chloroplast.hromoplasts (/KROME-ə-plasts/) are plastids, other than chloroplasts, that produce and store pigments. Found in flowers, leaves, roots and ripe fruits, they contain carotenoids (lipid-soluble pigments ranging from yellow to red in color), which lend color to the plant tissues containing them.
