Prokaryotic cells are generally small, with a simple internal structure (lacking organelles), where as the eukaryotic cell is generally larger a nd contains many internal organelles within the cytoplasm

What Is The Process Of Bulk Transport In The Body And Where Does It Take Place? Biology The movement of large materials into or out of cell is called as bulk transport
Cell Structures and Organelles - High School Biology
Possible Answers: rRNA proteins mRNA tRNA Correct answer: proteins Explanation: Remember that all three types of RNA are synthesized from DNA molecules. Messenger RNA (mRNA), on the other hand, can exit the nucleus and enter the cytosol, where it can bind to ribosomes and undergo translation; therefore, statement III is false
What are the similarities between photosynthesis and cellular respiration
The whole process involves plants using water, sunlight, and carbon dioxide to create oxygen and glucose, which is a form of sugar and serves as an energy source for the plant.Almost every part of the plant has evolved specifically to make the process of photosynthesis easier; therefore, almost every part of the plant is involved in photosynthesis. To understand photosynthesis is to build a foundation for examining the entire field of biology.Examine one of the many photosynthesis cycle diagrams to gain a better understanding of how the process works and continues over time
The cyclical nature of the two processes can be constructed visually, and the photosynthesis and respiration equations can be balanced in a descriptive and numerical format
Cell Types and Organelles
Prokaryotic Cell Prokaryotic cells are very small and mostly do not have organelles, the only exceptions being the cell membrane, cytoplasm, and ribosomes. The ribosomes are often found attached to the Rough Endoplasmic reticulum because after protein chains are assembled in the ribosome, they are taken to the rough ER for further assembly
Interactive Eukaryotic Cell Model
Smooth ER plays different functions depending on the specific cell type including lipid and steroid hormone synthesis, breakdown of lipid-soluble toxins in liver cells, and control of calcium release in muscle cell contraction. Smooth Endoplasmic Reticulum: Throughout the eukaryotic cell, especially those responsible for the production of hormones and other secretory products, is a vast network of membrane-bound vesicles and tubules called the endoplasmic reticulum, or ER for short
Widgets are generally produced in small shops around the city, these small shops can be built by the carpenter's union (whose headquarters are in town hall). The town hall has the instructions for widget making, widgets come in all shapes and sizes and any citizen of Grant can get the instructions and begin making their own widgets
Though unicellular, amoebas have a nucleolus but not a nucleus and all the cell organelles except mitochondria, therefore fulfilling the characteristics of eukaryotes. The three stages of cellular respiration are glycolysis, Krebs cycle, and the electron transport chain only when oxygen is present since electron transport requires the oxygen directly
Cells and Organelles
They are both surrounded by two bilayer membranes suggesting one membrane originated from the plasma membrane of the cell and one from the plasma membrane of the hypothetical invader. This is the endoplasmic reticulum (ER for short) and its central space or lumen is a continuation of the lumen between the membranes of the nuclear envelope
A series of metabolic pathways (the Krebs cycle and others) in the mitochondria result in the further breaking of chemical bonds and the liberation of ATP. Immediately after exposure to 14CO2, the plant's photosynthetic tissue is killed by immersing it in boiling alcohol, and all of the biochemical reactions cease
Cellular Respiration
Because there are a number of enzymes and steps involved in forming porphyrin rings, there are a number of possible points in the process where genetic defects could occur. Out of many possible types of fermentation processes, two of the most common types are lactic acid fermentation and alcohol fermentation (other types of fermentation such as methanol fermentation and acetone fermentation also exist)
Cellular Respiration:
In some ways similar to the chloroplast, the mitochondria also has two main sites for the reactions: The matrix, a liquidy part of the mitochondrion, and the christae, the folded membranes in the mitochondrion. In our cells, anaerobic respiration results in the production of lactic acid, the molecule that builds up when you 'feel the burn' during or after strenuous exercise
bacteriology - How do prokaryotes perform cellular respiration without membrane-bound organelles? - Biology Stack Exchange
This points you to the answer: bacteria produce ATPs the same way mitochondria do, with the oxidation machinery place in their plasma membrane (analogous to the mitochondrial membrane)
They are also involved in the digestion of food particles brought into the cell through infoldings in the plasma membrane Structure A membrane bound sac lysosomes are a small vacuoles or vesicles in the cytoplasm filled with digestive enzymes. Structure Each cilia (or flagella) is a circular series of 9 pairs of microtubules (often containing an additional central pair of tubules) surrounded by a long slender sheath of plasma membrane
In higher plants such as grains, trees, shrubs, red, brown and yellow algae and even some bacteria such as the blue-green cyanobacterias, photosynthesis involves chlorophyll a. Each part is made up of several chemical reactions -- some that occur in daylight, called light reactions, and others that occur in the absence of light, called dark reactions
Where Does Plant Respiration Take Place? Does Cell Respiration Only Take Place in Plant Cells? Cellular respiration is a metabolic process essential to the functioning of all cells. The cell makes a tiny amount of ATP during glycosis, but the primary reason for this step is the creation of intermediary chemical substances from glucose
