Why do plant species need to promote cross fertilization rather self fertilization?

Becuase when they self fertilize they cannot get the proper amount of sunlight, but when they dont self fertilize they can get the proper amount of sunlight

Why do plant species need to promote cross-fertilization rather than self-fertilizationWhy do plant species need to promote cross-fertilization rather than self-fertilization?
Cross fertilization leads to genetic variability which helps in the process of better adaptability and evolution
Why do plant species need to promote cross-fertilisation rather than self-fertilisation?
Pls replied the question to the answer back and I need the answer by tomorrow.
How does cross fertilization work?
The union of male and female reproductive cells from different individuals of the same species.
Why is the stigma a different height than the anthers?
The anthers and stigma occur at different heights to prevent self fertilization and to encourage cross fertilization.
What is fertilization of egg cells by pollen from a different plant?
Cross-Fertilization!

Self- and Cross-Fertilization in Plants. I. Functional Dimensions, by David G. Lloyd and Daniel J. Schoen © 1992 The University of Chicago Press.AbstractMany functional-ecological, morphological, and physiological-factors affect the occurrence of selffertilization. Six modes of self-pollination are distinguished. These differ in whether they utilize specialized flowers, whether they involve the transfer of pollen within or between flowers, whether they are autonomous or mediated by vectors, and their timing relative to opportunities for outcrossing. The various modes of selfing are subject to different structural constraints. Prepotency, the preferential success of cross-pollen in achieving fertilizations when it competes with self-pollen, influences the frequency of selffertilization in some species. The amount of self-fertilization may depend on environmental conditions and the vector species visiting each flower and may vary among the flowers of one plant. To gain information on the prevalence of autonomous self-pollination, 66 species for which the degrees of selfcompatibility and autofertility (seed set in isolation) have been published were surveyed. Partially selfincompatible species (in which the seed set is lower after self-pollination than after separate outcrosses) have on average lower autofertility than self-compatible species (in which self- and cross-pollinations succeed equally well), but some partially self-incompatible species have considerable autofertility and some self-compatible species have none. A number of features of floral morphology and phenology are associated with high Autofertility Indices.
What is the difference between self fertilization and cross fertilization?
welll because one is a producation but the other one isn't and the growth and how it grow at the botom of all top so it is werid Self-fertilization and cross-fertilization are the same as asexual and sexual reproduction. Self-fertilization uses itself to fertilize, which cross-fertilization takes from another plant to make a new generation of the plant.
What is this process in which the pollen from one plant is used to fertilize another?
cross fertilization
What is the name of the transfer of pollen from the stamina to the pistil?
pollination; if it from the same plant (self-fertilization; self-pollination); pollen from one plant to the stigma of another plant (cross-pollination; cross-fertilization)

cross fertilization
What is the process in which pollen is used from one plant to fertilize another?
cross fertilization
What process in which the pollen from one plant is used to fertilized another?
