## What is isomorphic alternation?

In an isomorphic alternation of generations (found in some algae, for example) the sporophyte and gametophyte are morphologically similar or identical; in a heteromorphic alternation of generations they are dissimilar (e.g. in mosses the gametophyte is the dominant and conspicuous generation, whereas in higher plants …

**Why does Ulva have isomorphic alternation of generation?**

In ulva the haploid zoospores give rise to the gametophytes. Both kinds of plants are morphologically identical and therefore ulva shows an isomorphic alternation of generations.

**What is isomorphic and heteromorphic alternation of generation?**

Species with heteromorphic life cycle have a large multicellular body in one generation but have a microscopic body in the other generation of a year. In contrast, isomorphic species have both diploid and haploid life forms with very similar morphology, having more than two generations in a year.

### What is the difference between isomorphic and Heteromorphic?

In biology|lang=en terms the difference between isomorphic and heteromorphic. is that isomorphic is (biology) having a similar structure or function to something that is not related genetically or through evolution while heteromorphic is (biology) having different forms in different stages of the life cycle.

**What is isomorphic life cycle?**

Isomorphic type: In this type, there are two exactly similar (morphologically identical) somatic phases (plants) showing alternation of generations. Here the one phase is diploid (sporophyte 2n) while the other haploid (gametophyte n). Among Chlorophyceae, this is found in Ulvaceae, Chaetophoraceae and Cladophoraceae.

**What is the life cycle of Ulva?**

Like many algae with complex life cycles, Ulva has a biphasic life cycle consisting of an alternation between two free-living forms, a haploid phase (1N, gametophyte) and a diploid phase (2N, sporophyte; Figure 1).

#### What is the difference between gametophytes and Sporophytes?

The plant’s haploid phase is called gametophyte and the diploid phase is called the sporophyte….

Difference Between Gametophyte and Sporophyte | |
---|---|

Sporophytes | Gametophytes |

Sporophytes have two sets of chromosomes | Gametophytes have a single set of chromosomes |

Sporophytes reproduce asexually | Gametophytes produce sexaully |

**What is isomorphic type of life cycle?**

Isomorphic type: In this type there are two exactly similar somatic phases (morphologically identical plants) showing alernaion of generations. Here the one phase is diploid (sporophyte 2n) while the other haploid (gametophyte n).

**What is isomorphic alternation of generation explain it by the life cycle of Ectocarpus?**

An alternation of generations occurs in the life cycle of Ectocarpus siliculosus growing in the region of Woods Hole. 2. The diploid asexual plants bear unilocular and plurilocular sporangia on separate individuals or simultaneously on the same individual. The zygotes develop into diploid asexual plants.

## What does the word Heteromorphic mean?

Definition of heteromorphic 1 : deviating from the usual form. 2 : exhibiting diversity of form or forms heteromorphic pairs of chromosomes.

**What is Diplobiontic?**

diplobiontic (not comparable) (botany) Describing a plant or fungus where both the haploid and diploid phases are represented by a multicellular phase. All embryophytes are diplobiontic.

**What is the difference between isomorphic and heteromorphic alternation of generation?**

Isomorphic alternation of generation – The diploid (2n) sporophyte and the haploid (n) gametophyte are not different in morphological structure. Heteromorphic alternation of generation – The diploid (2n) sporophyte and the haploid (n) gametophyte are clearly different in morphological structure.

### Is there a continuous deformation for two spaces to be homeomorphic?

But there need not be a continuous deformation for two spaces to be homeomorphic — only a continuous mapping with a continuous inverse function. In the mathematical field of topology, a homeomorphism, topological isomorphism, or bicontinuous function is a continuous function between topological spaces that has a continuous inverse function.

**What is the difference between self-homeomorphism andare homeomorphic?**

are homeomorphic. A self-homeomorphism is a homeomorphism from a topological space onto itself. “Being homeomorphic” is an equivalence relation on topological spaces. Its equivalence classes are called homeomorphism classes .

**What is homeomorphism in topology?**

In the mathematical field of topology, a homeomorphism, topological isomorphism, or bicontinuous function is a continuous function between topological spaces that has a continuous inverse function.
