Fungi are important decomposers in most ecosystems Most fungi are multicellular Fungi have cell walls made of chitin Fungi cannot run or fly in search of food Most fungi are autotrophs. Which one of the following structures is found in angiosperms but not gymnosperms. fruits spores seeds seed coat a tube that grows from the pollen to deliver spermExplanation / Answer
6. Fruits, vegetables, corn, rice and wheat are examples of D) Angiosperms.
These are the type of vascular plants that make up the spermatophytes (plants that produce seeds). They make flower and have seeds contained within a fruit. This is the most common type of plant, they make up over 80% of all plant species, and also they are the most diverse land plants.
7. Threadlike fungal filaments are called B) Hyphae.
Mycelia is the vegetative part of a fungus, made up of a network of fine white filaments known as hyphae. Hyphae’s are the main mode of vegetative growth, collectively called a mycelium. An exception is Yeasts, these are unicellular fungi that do not grow as hyphae.
8. The term a close association between two or more species is D) Colonialism.
Colonial organisms are present in close association in colonies composed of many physically connected, interdependent individuals. For example: Volvox, a unicellular algae.
9. Lichens: These are the composite organism arising from algae or cyanobacteria living among filaments or hyphae of fungi in symbiotic association. These are the indicator organisms in the environment and for centuries they are being used as sensitive bio indicators of air quality.
The false statement is option A.
10. Which one of the following statement is false: Statement E) most fungi are autotrophs, as we know that Fungi have a saprophytic mode of nutrition. They such nutrients from dead and decaying organic matter also they lack chlorophyll, so they cannot make their own food like autotrophs.
11. The difference in Angiosperm and gymnosperm is, A. Fruit, D) Seed coat, E) A tube that grows from the pollen to deliver sperm. Angiosperms are real fruit bearing plants, they possess seeds with covering, also they have ovaries but gymnosperms have no ovary.
