Chloroplasts are the food producers of the cell. The organelles are only found in plant cells and some protists such as algae.Animal cells do not have chloroplasts. ... The entire process is called photosynthesis and it all depends on the little green chlorophyll molecules in each chloroplast....
Where do amoeba and paramecium live? Do plant, animal, amoeba, and bacteria cells have DNA? How are amoebas helpful to humans? Can amoebas feel pain? Do amoeba euglena paramecium volvox have chlorophyll? How does single-celled amoeba breathe?
The presence of nuclear vacuoles during meiotic prophase has been shown in both animal (Rasmussen, 1976) and plant cells, including ferns (Sheffield and Bell, 1979; Sheffield, Laird and Bell, 1983), gymnosperms and angiosperms (Sheffield et al., 1979; Karasawa and Ueda, 1983a; Karasawa and...
Do plant cells have cell walls? Plant cells have certain distinguishing features, including chloroplasts,cell walls, and intracellular vacuoles. Photosynthesis takes place in chloroplasts; cell walls allow plants to have strong, upright structures; and vacuoles help regulate how cells handle water and s...
virus transport INTRODUCTION Like any other eukaryotic cells, plant cells are characterized by an elaborated secretory pathway composed of a complex network of organelles including the endoplasmic reticulum (ER), the Golgi apparatus, the trans-Golgi network (TGN), various end...

Because plant cells do not break down glucose by-products using oxygen, they do not have or need mitochondria. Instead, plants possess chloroplasts, which in effect convert light energy to chemical energy. Each plant cell has anywhere from 15 or 20 to about 100 chloroplasts, which, like mitoch...
Carrier effects of extracellular vesicles (EV) like exosomes refer to properties of the vesicles that contribute to the transferred biologic effects of their contents to targeted cells. This can pertain to ingested small amounts of xenogeneic plant miRNAs and oral administration of immunosuppressive exos...
B. Cells carry out active transport in three main ways Couple the uphill transport of one solute across membrane to the downhill transport of another. Couple uphill transport to the hydrolysis of ATP. Mainly in bacteria, couple uphill transport to an input of energy from light. ...
Except conserved proteinase domain, typical plant aspartic proteinases have a specific insert only in plant. After the separation of plant and animal, the gene family of aspartic proteinases has expanded largely ;these proteinases play important role in whole progress of plant growth and development, ...
