Distinguish between bacteria, protozoa, and fungi based on the following characteristics: cell size and internal/external structures (organelles), arrangements of cells, cell wall composition, motility.
Answer =
Distinguish between bacteria, protozoa, and fungi as follows:
Bacteria | protozoa | Fungi | |
cell size | They are small in size .about 0.5 to 5.0micrometer in length. | size is between 10 to 100 micrometer in diameter. | size is 2 to 10 micrometer. |
internal organelles | Chromosomes and ribosomes. | Golgi apparatus,mitochondria ,lysosome, food vacuoles. | mitochondria,endoplasmic reticulum and golgi apparatus. |
External organelles | Flagella, pilli, capsule, cell wall | pseudopodia, cilia and flagella. | Hypae, mycelium. |
arrangements of cells | Diplo,staphylo, strepto,tetrad and sarcina. | - | arrangement is called as coenocytic hypae. |
cell wall composition | peptidoglycan or murein | They lack cell wall. | chitin, glucans and glycoproteins. |
motility | motile.gliding type of motility due to flagella. | motile due to flagella, cilia. | Usually non motile. |
based on the following characteristics: cell size and internal/external structures (organelles), arrangements of cells, cell wall composition, motility.
