The glycocalyx is a type of identifier that the body uses to distinguish between its own healthy cells and transplanted tissues, diseased cells, or invading organisms. Included in the glycocalyx are cell-adhesion molecules that enable cells to adhere to each other and guide the movement of cells during embryonic development. [3]
Chlamydomonas reinhardtii is a single-cell green alga about 10 micrometres in diameter that swims with two flagella.It has a cell wall made of hydroxyproline-rich glycoproteins, a large cup-shaped chloroplast, a large pyrenoid, and an eyespot apparatus that senses light.
The algal cells are commonly found in the soil and water of many regions. Prototheca, especially P. wickerhamii and P. zopfii , can colonize the skin, fingernails, respiratory and digestive tracts. Prototheca algae cells can enter the bloodstream through open wounds, mucous membrane pathways, or the ingestion or inhalation of the cells.
Cyanobacteria (blue-green algae) bloom on Lake Erie (United States) in 2009. These kinds of algae can cause harmful algal bloom. A harmful algal bloom (HAB), or excessive algae growth, is an algal bloom that causes negative impacts to other organisms by production of natural algae-produced toxins, water deoxygenation, mechanical damage to other organisms, or by other means.
[1] [2] Prochlorococcus strains, called ecotypes, have physiological differences enabling them to exploit different ecological niches. [3] Analysis of the genome sequences of Prochlorococcus strains show that 1,273 [4] genes are common to all strains, and the average genome size is about 2,000 genes. [1] In contrast, eukaryotic algae have over ...
Over a 45-years span — between 1975 and 2020 — improvements in cancer screenings and prevention strategies have reduced deaths from five common cancers more than any advances in treatments ...
The chloroplasts of red algae have chlorophylls a and c (often), and phycobilins, while those of green algae have chloroplasts with chlorophyll a and b without phycobilins. Land plants are pigmented similarly to green algae and probably developed from them, thus the Chlorophyta is a sister taxon to the plants; sometimes the Chlorophyta, the ...
But my mom, who is a nurse, noticed that my white blood cell count was concerningly high, which could be a sign of infection or a bone marrow disease. This felt like a red flag, especially because ...
