Question

2.Fragmentation is the breaking of an organism into one or more pieces, each of which can develop into a new individual, true or false? 3. Karogamy is when: A. Haploid cells fuse their cytoplasms B. Haploid cells go through meiosis and become diploid cells C. Nuclei fuse to become diploid zygotes V coenocytic mycelium polysacharride that also comprise 1, the exoskeleton of crabs and cicadas obtain food from dead organic matter haustoria 2, parasites 3, secrete enzymes for digestion extra cellular digestion outside the body 4. a thin extension taht can penetrate living cells and absorb nutrients septa S. basic structure of a fungus 6. no septa so are multinucleate 7 a mass of hyphae 8. hypha vsepta obtaining energy from other organisms through absorption saprophytes 9. feeding off of and obtaining energy from a living organism crosswalls that separate cytoplasm and nuclei into cells vhypha 10. chitin absorpitive heterotrophs

Explanation / Answer

1. Coenocytic - 6. No septa so are multinucleate

Mycelium - 7. A mass of hyphae

Haustoria - 4. A thin extension that can penetrate living cells

Parasite - 9. feeding off of and obtaining energy from a living organism

Extracellular digestion - 3. Secrete enzymes outside the body

Septa - 10. Crosswalks that separate cytoplasm and nuclei into cells

Hypha - 5. Basic structure of fungus

Saprophytes - 2. Obtain food from dead organic matter

Chitin - 1. Polysaccharide in exoskeleton

Adsorptive heterotrophs - 8. Obtaining energy from other organisms through absorption.

2. True. It occurs in hydra, platform, microstomum etc.

3. C : karogamy is the final step in fusion where nuclei fuse together to form diploid nucleus.
