What are the unicellular organisms that resemble a bacterial cell and are found in fresh and sea water?
The unicellular organisms that resemble bacterial cells and are found in fresh and saltwater environments are called cyanobacteria. These organisms are photosynthetic, often forming blue-green blooms in water bodies, and play important roles in aquatic ecosystems as primary producers. They are also known for their ability to fix nitrogen from the atmosphere.
What are the main difference between mitochondrial and chloroplast DNA's?
The ribosomes of chloroplasts closely resemble bacterial ribosomes, while mitochondrial ribosomes show both similarities and differences that make their origin more difficult to trace.
What is the description of a chloroplast?
Chloroplasts occur in a variety of shapes and sizes, such as corkscrewlike ribbons or bracelet-shapes found in certain green algae. The chloroplasts of higher plants, however, tend to be shaped somewhat like two frisbees glued together along their edges, and when they are sliced in median section they resemble the outline of a football. Chloroplasts may be from 2 to 10 micrometers in diameter, and each is bounded by an envelope consisting of two delicate unit membranes . The outer membrane apparently is derived from endoplasmic reticulum whereas the inner membrane is believed to have orginated from the cell membrane of a blue-green bacterium. Within is a colorless, fluid, enzyme-containing matrix, called the stroma. Grana (singular: granum), which are stacks of coin-shaped double membranes called thylakoids are suspended in the stroma. The membranes of the thylakoids contain green chlorophyll and other pigments. Theses "coin-stacks" of grana, are vital to life as we know it on our planet today, for it is within the thylakoids that the first steps of the all-important process of photosynthesis occurs.
What does chloroplast DNA resemble?
Chloroplast DNA (cpDNA) resembles bacterial DNA in terms of size, structure, and gene content. This is because chloroplasts are believed to have originated from an ancient endosymbiotic event where a photosynthetic bacterium was engulfed by a eukaryotic cell.
Proteinoid microspheres are tiny bubbles that resemble cells because they?
are formed from small organic molecules that can self-assemble into spherical structures. These microspheres have a lipid bilayer-like structure, similar to cell membranes, which allows them to encapsulate other molecules and exhibit some basic cell-like properties. They are thought to be important stepping stones in the study of the origin of life on Earth.
The chloroplasts in eukaryotes closely resemble?
The chloroplasts in eukaryotes closely resemble cyanobacteria, as first noted by French scientist Andreas Schimper. Cyanobacteria are bacteria that produce energy for themselves through photosynthesis.
Where is granum located and what does it look like?
Granum is located within the chloroplasts of plant cells. It consists of stacks of thylakoid membranes, which are flat, disc-like structures that contain chlorophyll and other pigments. These stacks resemble a pile of coins or pancakes and are essential for the process of photosynthesis, as they facilitate the light-dependent reactions. The arrangement maximizes surface area for capturing light energy.
What alga does a trypanosome superficially resemble?
Trypanosomes superficially resemble spirulina, a type of filamentous cyanobacteria, due to their elongated and slender shape. Both spirulina and trypanosomes are unicellular organisms that are long and thread-like in appearance.
What is the process when bone forms directly within mesenchyme arranged in sheetlike layers that resemble membranes?
Intramembranous ossification process
The stongest evidence for the endosymbiotic origin of eukaryotic orgelles is the homology between extant prokaryotes and?
...eukaryotic organelles, such as mitochondria and chloroplasts. These organelles have their own DNA, ribosomes, and are similar in size to prokaryotes like bacteria. Additionally, the double membrane structures of mitochondria and chloroplasts resemble what is seen in prokaryotic cells.
