Most important different is nucleus. Bacteria has not real nucleus. Other different is ribosome bacteria has 70s but other has 80s, bacteria has not organelle but other has. These are most important differences.
Long answere should be written,briefly bacteria are procaryotes and having one circular chromosome and no definite nucleus and no true organells and hence bacteria are separated. To differentiate between fungi and algae, algae are photosynthetic organisms and having plstids in their cytoplasm but fungi not. Many differencies can be made between algae and fungi
Thank you so much for inviting me to this session. Unfortunately this amazing topic is out of my research domain so I can not post a scientific comment.
Fungi (singular Fungus') are organisms and micro-organisms within the fungal kingdom. Fungi are not plants or animals, although they survive and grow by getting nutrients from decaying plants and animals. Unlike plants, fungi do not photosynthesise (how plants get energy from sunlight and grow as a result). Fungi are important as they get nutrients back into the soil, and aid decomposition of plants. Various types of fungi can be eaten, as mushrooms (be careful though as some are poisonous and even deadly), or to make the yeast used in bread and beer. Other types can be used for medicinal reasons penicillin is a type of fungus. Not all fungi is good though, and certain types cause diseases and infections in humans (e.g. ringworm and athlete's foot) and plants.\
Algae (singular Alga') are organisms which are like plants. They are not the same though as they so not have roots, stems and leaves. However, like plants and unlike fungi, they do use photosynthesis (explained above). Algae grow in water, and include seaweed, and other fresh water plants. Algae are important to the ecological systems in water.
Although algae are plants and fungi are not, they do share similarities. They are both important parts of nature one on land, and one in water
The Bacteria [bækˈtɪərɪə] (help·info) (singular: bacterium) are a large group of unicellular microorganisms. Typically a few micrometres in length, bacteria have a wide range of shapes, ranging from spheres to rods and spirals. The name derives from the Greek βακτήριον, baktērion, meaning "small staff".) Bacteria are ubiquitous in every habitat on Earth, growing in soil, acidic hot springs, radioactive waste, water, and deep in the Earth's crust, as well as in organic matter and the live bodies of plants and animals. There are typically 40 million bacterial cells in a gram of soil and a million bacterial cells in a millilitre of fresh water; in all, there are approximately five nonillion (5×1030) bacteria on Earth,forming much of the world's biomass. Bacteria are vital in recycling nutrients, with many important steps in nutrient cycles depending on these organisms, such as the fixation of nitrogen from the atmosphere and putrefaction. However, most bacteria have not been characterized, and only about half of the phyla of bacteria have species that can be cultured in the laboratory. The study of bacteria is known as bacteriology, a branch of microbiology
Dear Dr .What distinguishes bacteria is prokayriotic organism. While Algae and fung are both eukaryotas but algae are able to make their own food by chlorophyll While fungi are not self - feeding. Accept my greetings
