What would be the likely function of a plant cell that contains many chloroplasts?
What would be the likely function of a plant cell that contains many chloroplasts?
Chloroplasts work to convert light energy of the Sun into sugars that can be used by cells. The entire process is called photosynthesis and it all depends on the little green chlorophyll molecules in each chloroplast. Plants are the basis of all life on Earth.
What is mitochondria short answer?
Mitochondria (sing. mitochondrion) are organelles, or parts of a eukaryote cell. They are in the cytoplasm, not the nucleus. They make most of the cell’s supply of adenosine triphosphate (ATP), a molecule that cells use as a source of energy. This means mitochondria are known as “the powerhouse of the cell”.
Why do mitochondria appear to have different shapes?
Mitochondria vary in shape from bean-like units to a lattice-like form, so when thin sections of a cell are made for microscopy, they will show different orientations. Fission and fusion continually occur in healthy cells. The shapes can change with the presence of free radicals and when cells are dying.
What organelles do thyroid cells likely have a lot of?
During estrus, the thyroid gland is composed of small and medium follicles. The follicular cells contain mitochondria with lamellar cristae, well developed rough endoplasmic reticulum and Golgi complex and large number of dense bodies.
What organelles would you expect to see in higher concentrations in pancreatic cells?
Pancreatic gland cells produce and secrete large amounts of digestive enzymes. Which organelles would you expect to be present in higher than normal amounts in such cells? Rough E.R. are responsible for the assembly of protiens (enzymes are proteins) and the Golgi Apparatus is responsible for the delivery of proteins.
How many ribosomes are in a pancreatic cell?
several million ribosomes
Why would you expect to find a large number of ribosomes in pancreatic cells?
Amino acids are the building blocks of proteins. Ribosomes are particularly abundant in cells that synthesize large amounts of protein. For example, the pancreas is responsible for creating several digestive enzymes and the cells that produce these enzymes contain many ribosomes.
Do ribosomes need energy?
Ribosomes are the cellular structures responsible for protein synthesis. Protein from your diet is broken down into individual amino acids which are reassembled by your ribosomes into proteins that your cells need. Ribosomes do not produce energy.
Why can’t you see ribosomes in a light microscope?
Explanation: Some cell parts, including ribosomes, the endoplasmic reticulum, lysosomes, centrioles, and Golgi bodies, cannot be seen with light microscopes because these microscopes cannot achieve a magnification high enough to see these relatively tiny organelles
