How are plantae protists and stramenopila (diatom) different and similar?
Diatoms: are a major group of eukaryotic algae (single celled algae), and are one of the most common types of phytoplankton. Most diatoms are unicellular and some are colonial algae, live in water, both heterotroph and autotroph, yellow brown chloroplast, they are sessile (don't have flagella however move by water stream as they float), reproduce by cell division. they are not considered to be plants because they are unicellular.
similarity: both are producers (bottom of food chain), photosynthetic
difference: plants are multicellular, diatoms are unicellular, plants reproduce by meiosis where as diatoms by cell division, most plants live on land where as diatoms strictly live in wet environment. plants are more complex and larger whereas diatoms are smaller (microscopic), there are out layer differences: plants have cell wall made of cellulose where as diatoms have cell wall made of silica, plants don't form colonies where as diatoms can form colonies, also there is chlorophyll (pigment) differences: plants usually have green chlorophyll whereas diatoms have yellow and brown pigments, some diatoms are capable of movement where as plants can move, and some diatoms are heterotrophic where as plants are strictly autotrophic. diatoms have different life cycles (alteration of generation), diatoms reproduce asexually by mitosis. diatoms fossilize when they die as rocks at the bottom of water, plants normally get eaten by decomposers. diatoms are more closely related to bacteria where as plants are more closely related to Eukaryote
