The pistil is the female reproductive part of the flower, consisting of the ovary, style, and stigma.

The pistil is the female reproductive part of the flower, consisting of the stigma, style, and ovary.

The fertilized egg is called a zygote, which is the initial stage of development before it becomes an embryo.

Speciation is the process through which new species arise from existing species due to evolutionary changes.

Speciation is the evolutionary process by which new biological species arise.

Fertilization is the process where the male gamete (sperm) fuses with the female gamete (egg) to form a zygote.

Fertilization is the process where the male and female gametes fuse to form a zygote.

Fertilization is the term used for the fusion of sperm and egg, leading to the formation of a zygote.

The genetic makeup of an organism is referred to as its genotype.

Mutation refers to random changes in DNA that can lead to genetic variation within a population, which is a key factor in evolution.

Succession refers to the process of change in the species structure of an ecological community over time.

Evolution refers to the gradual change in species over time, driven by mechanisms such as natural selection and genetic drift.

Global warming refers specifically to the long-term rise in Earth's average surface temperature due to human activities.

Global warming refers specifically to the gradual increase in Earth's average temperature due to human activities.

Global warming refers specifically to the long-term rise in the average temperature of the Earth's atmosphere due to human activities.

Succession is the process of change in the species structure of an ecological community over time.

Succession refers to the process of change in the species structure of an ecological community over time.

Extirpation refers to the loss of a species from a particular habitat, while extinction refers to the loss of a species globally.

Habitat fragmentation leads to the loss of biodiversity as it divides ecosystems and isolates species.

Genetic erosion refers to the loss of genetic diversity within a species, which can threaten its survival.

Transpiration is the process of water vapor loss from the aerial parts of plants, mainly through stomata.

Transpiration is the process of water vapor loss from the aerial parts of the plant, mainly through stomata.

The male gamete in flowering plants is contained within the pollen grain.

The stamen is the male reproductive part of the flower, consisting of the anther and filament.

Carrying capacity is the maximum number of individuals of a particular species that an environment can support sustainably.

Osmosis is the movement of water across a semi-permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Transpiration refers to the process of water movement through a plant and its evaporation from aerial parts, which helps in moving water against gravity.

Translocation refers to the movement of water and nutrients through the plant, specifically from roots to leaves.

Phenotype refers to the observable characteristics of an organism, influenced by its genotype and environment.

The calyx is the outermost whorl of a flower, made up of sepals that protect the flower bud.
