Adisadvantage of the morphospecies concept is that it cannot be applied to: extinct organisms (e. g., fossils). polymorphic species and cryptic species. polymorphic species (species with more than one morphology). cryptic species (species that are very similar in appearance). none of the answer options is accurate.

Cryptic species (species that are very similar in appearance).

Explanation:

The concept of morphological species characterizes a species on the basis of structural features and body shape. It is applied to sexual as well as asexual organisms. It is an useful approach when the information about the gene flow is unknown. It is subjective approach.

The disadvantage associated with the morphological species concept is that the concept cannot distinguish between the Cryptic Species, those that have species actually have differences other than the morphological ones.

a. seed plant structure. 1. the three main plant organs are roots, stems, and leaves. a fourth kind of tissue, meristematic tissue, is responsible for plant growth. meristematic tissue is the only plant tissue that produces new cells by mitosis. plants can lose water out of their leaves as they exchange gases with the air

explanation:

cells use diffusion to get substances in and out of themselves. that diffusion will occur across the cell membrane or the outer covering of the cell. because we are talking about the surface of the cell, surface area and volume are  important factors here. as a cell increases in size, its surface area and volume increase as well.  we call that the surface area to volume ratio (sa: vol).  but the catch is that  volume increases at a greater rate than surface  area. in other words, as a cell gets bigger, the sa: vol gets smaller. so a really small cell like bacteria is mostly cell membrane (surface) with very little contents (volume). a really big cell like an egg, is mostly insides with a super thin membrane. so what ends up happening is that the cell cannot efficiently diffuse all of the stuff it needs in/out to survive. therefore cell size is limited to about 100mm. so how do we make organisms bigger than 100mm? cells divide! by dividing and becoming multicellular, organisms are able to grow!   check out the diagrams i attached to see the effect of sa: vol. i hope this ! good luck!
