Sorry, I cannot see a statement to choose from.
Answer:
Testa, Protect, Desiccation, Feezer, Two, Cotyledons, Embryo , Plumule, Radicle
Explanation:
Seed germination is defined as the process of growing of a seed that involves causing a seed to sprout.
There are three primary parts seeds embryo, endosperm and seed coat. The outer covering of seed is called Testa which is seed coat that protects the seed from desiccation and external harmfull condition of environment.
The seed are stored in freezer that keeps it dry and cool. A temperature between 32° and 41°F is ideal for storing seeds.
Seeds are dvided into two halves called cotyledons. The new plant germinating is called an embryo which has two parts named plumule and radicle. Plumule grows into stem while radicle grow sinto root under favuorable conditions.
Hence, the correct answer in the blanks are Testa, Protect, Desiccation, Feezer, Two, Cotyledons, Embryo , Plumule, Radicle.

Answer:
In bryophytes, the sporophyte is minute and dependent on the relatively prominent and nutritionally independent gametophyte for resources. The moss gametophyte looks like a miniature herb, with tiny leaf-like photosynthetic organs. The gametophyte generation begins as a dormant spore, which germinates under appropriate conditions to produce filamentous and branching protonemal tissues. These form multicellular bud-like structures, each of which develops into a leafy shoot. The mature gametophytes produce male and female sexual organs, the antheridia and archegonia, respectively. The gametophyte is often sexually distinct, and plants are either male or female.
Each antheridium has an outer layer that encloses and protects thousands of motile sperm, which swim through available external water layer to the egg. Fertilization at the base of the cylindrical archegonium produces a diploid zygote which develops into an unbranched sporophyte. The sporophyte consists of a thin stalk attached to the gametophyte, and a capsule that encloses the sporophytic meiotic cells.
In recent years, the mosses Physcomitrella patens and Funaria hygrometrica have emerged as attractive model systems for studying gene function in non-vascular plants because of the relative ease of molecular manipulation by homologous recombination. Mutants affecting gametophyte development have been isolated and their analysis should provide insights into the molecular basis of gametophyte development in mosses.
