One gets together with another and it happens then a child comes
California is home to the largest, tallest, and oldest trees on earth, all of which are gymnosperms.
Gymnosperms are plants that have seeds and are usually coniferous trees. Given that those largest, tallest, and oldest trees are sequoias, this seems to be the correct answer.
Nonvascular plants are quite small. Seedless vascular plants is also incorrect, because sequoias have seeds. Angiosperms are flowers.
There are three stages in the life cycle of a spider : - the first is embryonic stage, then the larval stage and finally nympho- imginal stage.
Answer: The correct statements are 1 and 2:
1.Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant.
2.Cross-pollination is the transfer of pollen from the anther of one flower to the stigma of another flower on a different individual of the same species.
Explanation:
Pollination is the transfer of pollen grains from an anthers to a receptive stigma. In most species of flowering plants, external agents bring about pollination. Also, flowers have evolved special structures and mechanisms to ensure successful pollination.
There are two types of pollination
--> Self pollination: This takes place when mature pollen grains from the anther of a flower fall on the stigma of the same flower or that of another flower on the same plant. This type of pollination brings the male gametes and egg cells of the same plant together. The resultant offspring show very little genetic variation.
--> Cross pollination: This occurs when mature pollen grains of a flower are transferred to the stigma of a flower of another plant of the same or closely related species. This brings the male gametes and egg cells of two different parent plants together. Therefore, there is greater genetic variation among the offspring.
Answer:
Among the choices the statement that best describes the relationship of photosynthesis and energy is letter A, the process of photosynthesis is energy-storing because the process converts light energy into chemical energy, which is stored in the bonds of glucose.
