Hint: In Latin, the word flora means "Goddess of the Flower." Flora is a collective term used in a specific area for a community of plant life. By this name, the entire plant kingdom is represented. Based on several variables, flora is graded and distinguished. The region in which they grow or are found is the best one among them.Some are found in hilly areas in desert regions or in water, while some are endemic to a particular geographic location.
Complete answer:
Note: For human life, flora and fauna are very crucial. For breathing activities, the flora releases oxygen that is absorbed by the fauna. In exchange, fauna releases the carbon dioxide that flora consumes for photosynthesis.
Through its medicinal and food offerings, flora and fauna support humanity enormously.
Complete answer:
| Red algae | Brown algae |
| Under the class Rhodophyceae, red algae are grouped. | Under the class Phaeophyceae, brown algae are grouped. |
| As stored food, they produce Floridean starch. | As stored food, they contain mannitol or laminarin. |
| They include chlorophyll a and d, photosynthetic pigments, and phycoerythrin. | They include chlorophyll a and c, and fucoxanthin, the photosynthetic pigments. |
| Cellulose, pectin, and phycocolloids comprise their cell walls. | Their cell walls are made of alginate and cellulose. |
| Flagella is absent | There are two flagella present |
| Liverworts | Moss |
| They have rhizoids that are unicellular. | They have rhizoids that are multicellular. |
| Scales are also frequently present, | Scales are missing |
| Generally, with dichotomous branching, they are thalloid. | With lateral branching, they are foliage. |
| Gemma cups are available, | Gemma cups are absent |
| There is very little photosynthetic tissue in sporophyte, | The photosynthetic tissue of sporophyte is abundant |
| Homosporous pteridophyte | Heterosporous pteridophyte |
| They bear spores which are of the same nature. | Two kinds of spores are borne by them: microspores and megaspores. |
| Bisexual gametophytes are formed by them. | They generate gametophytes that are unisexual. |
| Syngamy | Triple fusion |
| It is the method of fusion of an angiosperm with the egg of the male gamete. | It is the method of fusion of the male gamete in an angiosperm with the diploid secondary nucleus. |
| As a result of syngamy, a diploid Zygote is formed. | As a result of triple fusion, a triploid primary endosperm is formed. |
Note: For human life, flora and fauna are very crucial. For breathing activities, the flora releases oxygen that is absorbed by the fauna. In exchange, fauna releases the carbon dioxide that flora consumes for photosynthesis.
