Bacteria are prokaryotic cells, meaning that they do not have a membrane-enclosed nucleus. Eukaryotes have cells with am enclosed nucleus. Where in these types of cells can DNA be found? Prokaryotic cells, with no nucleus or membranous organelles, are found in what? A) ...
What kind of cells has viruses that can infect them? What are chronic diseases? What are microbes? What are viruses? What type of cell is responsible for the most dangerous form of skin cancer? Which is the major virus involved in the development of cervical cancer?
The cells of plants, bacteria, algae, and fungi have an extra layer of protection over their cell membrane—the cell wall. This is usually made to be hard and tough, which is one reason plants are so sturdy. The Inner City – The Cytoplasm Moving inside the cell, we come to the cytop...
Tardigrades don't live in or on humans, and they are not dangerous to us. What do tardigrades eat? Most tardigrades suck fluids from cells in plants, algae and fungus. They use needle-like structures in their mouths to pierce cell walls and vacuum up the liquid inside. However, some...
Algae (singular alga) are a large group of diverse organisms that use photosynthesis to produce food. Although some forms are large and multicellular, they differ from plants in that their cells are not clearly organized into different types of tissue with different functions. This group includes ...
Environmental conditions such as the amount of oxygen and water flow will determine the extent to which the biofilm colony can grow (how many layers it will be made up of). Clumps of microorganisms can break away from the colony together or individual cells will burst out to move on and se...
moist soils etc. They are one of the earliest colonizers. They can be unicellular, filamentous or occur in colonies. The filament has mucin covering. There are no flagella for locomotion of bacteria. Their cells are larger than normal bacterial cells. Their cell wall is multi layered. It incl...
Docosahexaenoic acid, or DHA is a type of omega-3 fatty acid that's found in certain foods and supplements, including many types of fish and algae. Omega-3 acids are important parts that form all sorts of cells in your body, especially in the eyes and brain. Why Is DHA so Important ...
Plants move, for example in response to light, and aggregate colonies of plant cells, for example, in the case of volvox algae, move toward the light, but these movements are not initiated by the plant, they are metabolic processes. Animals have the possibility to initiate their own action,...
Cyanobacteria, also known as blue-green algae, are microscopic, photosynthetic bacteria. They are prokaryotic, meaning their cellular structure is simple, without a defined nucleus. Algae, on the other hand, are primarily eukaryotic, which means they have complex cells with a defined nucleus and or...
