What are the similarities between bacteria and algae?

Answer 1

The differences between bacterial and algal cells is encompassed mostly by the differences between prokaryotic and eukaryotic cells.

I'll start by listing characteristics unique to bacteria. These prokaryotic organisms range from 0.2-2.0 micrometers in diameter. They reproduce asexually by binary fission or budding. In limited cases, bacteria can exchange genetic material through a pilus which anchors them together. This is as close to sexual reproduction that bacteria get. Their DNA is circular and often exists in many duplicated forms within the cell. The circular chromosome lies within the cytosol of a bacterial cell. Bacterial cell walls are make of peptidoglycan, a composition unique to the genus. Depending on the thickness of their cell wall, they are classified as either gram positive or gram negative species. Bacteria have appendages that are used for locomotion and attachment to environmental surfaces. These include, flagella, pili, fimbriae and components of their glycocalyces. Some bacteria have photosynthetic capabilities- like algae.

Algae are eukaryotic, phototropic organisms. Their cell walls are composed of components such as cellulose, proteins, agar, carrageenan, silicates, algin, calcium carbonate depending on the species. They also have cell membranes, like all Eukaryotes. Reproduction is sexual in multicellular organisms and follows an alternating pattern of haploid and diploid generations. Unicellular algal species reproduce asexually by fragmentation. In this process, each new fragment becomes a gamete and develops into an entire entity. They have membrane bound organelles within their cytoplasm including photosynthetic pigments. Algae are classified based on the type of pigments they use for photosynthesis, what their cell wall composition is and what by product they create in photosynthesis.

This list includes some of the most general differences between these two cell types. Of course, there are entire books dedicated to each of these cell types, their metabolisms, morphology & more...

Answer 2

Prokaryotes have 70S ribosomes, each consisting of a small (30S) and a large (50S) subunit.

Eukaryotes have 80S ribosomes, each consisting of a small (40S) and large (60S) subunit.

Any many other differences.

Answer 3

Both algae and bacteria are microorganisms. A great number of algae and bacteria are single-celled creatures. They get their food via photosynthesis.

Answer 4

compare and contrast bacteria cells to other cells

Answer 5

the bacterial cell wall is made of peptidoglycan and is different from plant an fungi cell walls that are made of cellulose and chitin

Answer 6

there is no difference

Answer 7

bacteria cells can be good or bad

there are different types of bacteria that live inside your body

compared to other cells:

they can easily get remove from your body

and they can travel
