Tubular elements - a new structure in blue-green algal cells
Journal of Cell Science
|December 1, 1977
Summary
Researchers discovered novel tubular elements within the blue-green alga Calothrix marchica. These unique cell inclusions, measuring 18-22 nm, appear in approximately 20% of observed cells.
Area of Science:
- * Cell Biology
- * Microbiology
- * Phycology
Background:
- * The blue-green alga Calothrix marchica is a common cyanobacterium.
- * Understanding cellular structures is key to deciphering microbial physiology.
Purpose of the Study:
- * To describe newly identified cell inclusions in Calothrix marchica.
- * To characterize the morphology and prevalence of these novel structures.
Main Methods:
- * Microscopic observation of Calothrix marchica cells.
- * Morphological analysis of newly discovered cell inclusions.
Main Results:
- * Identification of novel intracellular structures termed 'tubular elements'.
- * Tubular elements observed in approximately 20% of cells.
- * Measured diameter of 18-22 nm, with 8-10 subunits per transverse section.
Conclusions:
- * Tubular elements represent a previously undescribed cellular component in Calothrix marchica.
- * Further research is needed to determine the function of these tubular elements.

01:08The Anatomy of Chloroplasts
Green algae and plants, including green stems and unripe fruit, harbor specialized organelles called chloroplasts to carry out photosynthesis. They coordinate both stages of photosynthesis — the light-dependent reactions and the light-independent reactions. The light-dependent reactions use sunlight to release oxygen and produce chemical energy in the form of ATP and NADPH, and the light-independent reactions capture CO2 and use ATP and NADPH to produce sugar.

01:27Cell Inclusions
Prokaryotic cells possess a variety of inclusions that play crucial roles in nutrient storage, metabolic processes, and environmental adaptation. These structures enable bacteria to thrive under fluctuating environmental conditions by storing essential resources and optimizing their metabolic efficiency.Carbon Storage: Poly-β-Hydroxybutyric Acid and Glycogen GranulesBacteria frequently store excess carbon in specialized granules. Poly-β-hydroxybutyric acid (PHB) granules are lipid polymers that...
01:28Overview of Algae
The kingdom Archaeplastida encompasses red and green algae, along with land plants. Unlike other protists with chloroplasts that arose through secondary endosymbiosis, only red and green algae originated from primary endosymbiotic events. This diverse group of eukaryotic organisms contains chlorophyll and performs oxygenic photosynthesis.Algae exist in various forms, from large brown kelp in coastal waters to green scum in puddles and stains on rocks or soil. Some species are responsible for...
01:23Red Algae
Red algae, also known as rhodophytes, are primarily found in marine environments, though some species inhabit freshwater and terrestrial ecosystems. These organisms exist in both unicellular and multicellular forms, with some multicellular varieties reaching macroscopic sizes.As phototrophic organisms, red algae contain chlorophyll a; however, their chloroplasts lack chlorophyll b. Instead, they possess phycobiliproteins, which serve as major light-harvesting pigments, similar to those found in...
01:21Green Algae
Green algae, also referred to as chlorophytes, are different from red algae in having the chloroplasts containing chlorophylls a and b, which give them their distinct green hue. However, they lack phycobiliproteins, preventing them from developing the red or blue-green pigmentation seen in red algae. In terms of photosynthetic pigment composition, green algae closely resemble plants and share a close evolutionary relationship with them. Taxonomically Green algae belong to Phylum Chlorophyta in...
01:19Other Algae
The group Stramenopiles include some phototrophic microorganisms. Members of this group possess flagella covered in numerous short, hairlike extensions, a feature that inspired the group's name, derived from the Latin words for "straw" and "hair." Some of the main categories of Stramenopiles include diatoms, golden algae, and brown algae.Diatoms are unicellular, photosynthetic eukaryotes, with over 200 known genera. They play a key role in the planktonic communities of both marine and...
