Consider the terms egg, sperm, and sporophyte. Which term links egg and sperm directly to sporophyte?
NARA [144]

Answer:

Explanation:

La fecundación es el proceso por el cual dos gametos (masculino y femenino) se fusionan durante la reproducción sexual para crear un cigoto con un genoma derivado de ambos progenitores. Los dos fines principales de la fecundación son la combinación de genes derivados de ambos progenitores y la generación de un cigoto.

En el caso de las plantas con semillas pros, hay que diferenciar el fenómeno de la fecundación propiamente dicho (unión íntima de dos células sexuales hasta confundirse sus núcleos respectivos y, en mayor o menor grado, sus citoplasmas),1​ del proceso biológico que lo antecede: la polinización, en el que los granos de polen, desarrollados en las tecas que contiene cada antera de un estambre (hoja reproductora masculina), son transportados por el viento o los insectos a los estigmas, donde germinan emitiendo un tubo polínico que crece hacia el ovario. En este caso no se trata de gametos, sino de esporas, pues cada grano de polen contiene dos gametos o células reproductoras masculinas

How do the laws of thermodynamics relate to the transformation of energy in organisms? Use the terms autotroph and heterotroph w
yarga [219]

Answer:

he organisms that can fix energy from inorganic sources into organic molecules are called autotrophs. Organisms that cannot make their food from inorganic sources but depend on energy rich organic molecules synthesized by autotrophs for their energy needs are called heterotrophs.

The only source of energy for all the ecosystems of the earth is the sun. Light falling on the plants is trapped by the producers or autotrophs in the presence of chlorophyll and is used in synthesizing the organic food called glucose by the process of photosynthesis. By photosynthesis radiant energy of sunlight is transformed into potential energy of food. A part of this energy is trapped by the producers while the rest of the energy is dissipated. The remaining part of energy which is used in the synthesis of plant biomass is called photosynthate which is then available to the next trophic level in the food chain that is the consumers or heterotrophs. In an ecosystem there is a unidirectional flow of energy.
