2 diploid cells that are genetically identical to the parent cells
homeostasis is done throughout the whole body not particular parts or organs so when the body temperature rises the sweat glands all-over the body secretes sweat to lower down the temperature of the body
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.
Explanation:
Answer:
Anabolic reactions use ATP and small substrates as building blocks to synthesize larger molecules.
Explanation:
Anabolic reactions are part of metabolic pathways that occur inside the living cells. Anabolic reactions always form complex molecules from simpler substances. The formation of glucose from relatively simpler CO2 and H2O during the Calvin cycle is an example of the anabolic pathway. During anabolic pathways, the metabolic energy of ATP hydrolysis drives the endergonic reactions. Therefore, anabolic reactions consume ATP. Calvin cycle uses the ATP produced during light reactions of photosynthesis.
