Pineberry is a hybrid cross from Fragaria chiloensis and Fragaria virginiana. [1] A pineberry is smaller than a common strawberry, measuring between 15 and 23 mm (0.6 and 0.9 in). When ripe, it is almost completely white, but with red achenes (the seeds). The plant is disease-resistant, and highly priced, although not profitable due to small ...
Little is known about how ctenophores get rid of waste products produced by the cells. The ciliary rosettes in the gastrodermis may help to remove wastes from the mesoglea, and may also help to adjust the animal's buoyancy by pumping water into or out of the mesoglea.
Also called functionalism. The Darwinian view that many or most physiological and behavioral traits of organisms are adaptations that have evolved for specific functions or for specific reasons (as opposed to being byproducts of the evolution of other traits, consequences of biological constraints, or the result of random variation). adaptive radiation The simultaneous or near-simultaneous ...
A female pinecone produces the megaspores of this heterosporic plant.A male pinecone produces the microspores of this heterosporic plant.Heterospory is the production of spores of two different sizes and sexes by the sporophytes of land plants.
A recent study shows that without plant breeding, Europe would have produced 20% fewer arable crops over the last 20 years, consuming an additional 21.6 million hectares (53 million acres) of land and emitting 4 billion tonnes (3.9 × 10 9 long tons; 4.4 × 10 9 short tons) of carbon.
The gametophytes of bryophytes, and less commonly ferns and lycopods can develop a group of cells that grow to look like a sporophyte of the species but with the ploidy level of the gametophyte, a phenomenon known as apogamy. The sporophytes of plants of these groups may also have the ability to form a plant that looks like a gametophyte but ...
F1 hybrid (also known as filial 1 hybrid) is the first filial generation of offspring of distinctly different parental types. [1] F1 hybrids are used in genetics, and in selective breeding, where the term F1 crossbreed may be used. The term is sometimes written with a subscript, as F 1 hybrid. [2] [3] Subsequent generations are called F 2, F 3 ...
Pineberry [35] [36] Pineberries are smaller than a common strawberry, measuring between 15 and 23 mm (0.6 and 0.9 in). When ripe, they are almost completely white, but with red "seeds" . The plant is disease resistant and has small berry size and low yield. [37] [38] It is available in the spring and summer. Pink Panda (see ' Frel ') [2]
