Explain why no organelles, such as a nucleus, are seen in the Anabaena. (Please type it out)

Expert Solution

The main difference between prokaryotes and eukaryotes is the presence of the membrane-bound cell organelles. Eukaryotes are named as eukaryotes because of the presence of the true nucleus and other membrane-bound cell organelles like chloroplast, mitochondria. On the other hand, Prokaryotes do not have a nucleus and any other membrane-bound cell organelles.

Bacteria and Archaebacteria are included in the Prokaryotes.

Anabaena is a type of cyanobacteria that does oxygenic photosynthesis but it is not considered as the true algae due to the absence of the nucleus. Anabaena is a filamentous cyanobacterium and acts as the nitrogen-fixing bacteria due to the presence of the specialized cells known as heterocyst. But they are not included in the algae due to the absence of the membrane-bound Cell organelles. They remain as plankton and do the nitrogen fixation. Anabaena is included in the domain Bacteria thus they are Prokaryotes and do not have any membrane-bound cell organelles.

1. We know fungi are eukaryotic (have membrane-bound nucleus and organelles). Explain three unique ways fungi are different from other microbes (algae, protozoans, bacteria and archaea). Compare things like cell walls, cell membranes, morphology, reproduction, life cycles. 2. Algae and protozoans are loosely grouped together as protozoans and are different from plants because they lack certain characteristics of plants. Explain what differentiates algae from plants and two ways they are different from protozoans. Talk about algae being part of our...

Describe the structure and function of each of the following organelles: Nucleus, Endoplasmic reticulum (both rough and smooth), Golgi Apparatus, Lysosomes, Mitochondria, Chloroplasts (Thylakoids), and the components of the endomembrane system (how are the components of the endomembrane system connected to one another). What is a vacuole, what it does and where it comes from. Which organelles contain their own DNA? Where do lysosomes come from?
