After fertilization in a plant occurs, other changes may occur. An embryo - which is the future plant - is formed, endosperm cells become the embryo's source of nutrition, the ovule of the plant is now the seed, the ovary becomes the fruit of the plant, and the petals and sepals will fall off of the plant.
After fertilization, the ovule develops into a seed. The zygote formed after fertilization undergoes multiple rounds of cell division to form an embryo inside the seed. Surrounding the embryo, the ovule's integuments develop into the seed coat, providing protection. Nutrients accumulate in the seed to support the growing embryo, allowing it to survive and germinate when conditions are favorable.

What does microangiopathic changes mean?
Microangiopathic changes refer to pathological changes that occur in small blood vessels, leading to vessel damage and dysfunction. This can include thickening of vessel walls, narrowing of the vessels, and formation of microthrombi. These changes can impair blood flow to tissues and organs, leading to various complications.
Describe three changes in appearance which show that a chemical reaction is taking place?
Change in color: If the reactants and products have different colors, a visible color change can indicate a chemical reaction. Formation of a gas: Production of bubbles, froth, or fizzing can indicate a gas is being released during a chemical reaction. Formation of a precipitate: If a solid substance forms in a solution, it can indicate that a chemical reaction has occurred leading to the formation of an insoluble product.
What is the disease that involves changes in the nerves and chemicals of the brain leading to memory loss personality changes and complete dependency?
Alzheimer's disease is a neurodegenerative disorder that causes changes in the brain's nerve cells and chemicals, leading to symptoms like memory loss, personality changes, and eventual complete dependency on others for care.
Is formation of clouds is chemical?
The formation of clouds is a physical process, not a chemical one. It involves the condensation of water vapor in the atmosphere as it cools, leading to the tiny droplets that make up clouds. While there are chemical processes at play in the atmosphere, the initial formation of clouds is primarily a result of physical changes in temperature and pressure.
Which physical processes result in the formation of metamorphic rocks?
Metamorphic rocks form when existing rocks undergo changes in temperature and pressure due to processes such as tectonic plate movement, burial deep within the Earth's crust, or contact with hot intrusions. These changes cause the minerals in the existing rocks to recrystallize and reorganize, leading to the formation of metamorphic rocks.
Describe how temperature changes can make cracks form in rocks?
Temperature changes cause rocks to expand and contract, leading to stress within the rock. Over time, repeated expansion and contraction can weaken the rock and lead to the formation of cracks. Additionally, differential rates of expansion and contraction in different parts of the rock can cause internal forces that contribute to crack formation.

What term is used to describe changes in variable that are associated with the relationship of an individual to others?
The term used to describe changes in variables associated with an individual's relationship to others is "social dynamics." This concept encompasses how individuals interact, influence, and are influenced by the people around them, leading to changes in behavior, attitudes, and emotions.
Process of new species formation does this scenario describe?
This scenario describes allopatric speciation, where a population becomes geographically isolated and subsequently diverges genetically and reproductively from the original population, leading to the formation of a new species over time.
What words describe the reaction of an acid and a alkali?
Neutralization reaction occurs when an acid and an alkali react, resulting in the formation of water and a salt. This reaction typically involves the transfer of protons from the acid to the alkali, leading to the formation of a neutral solution.
Which process of new species formation does this scenario describe?
The scenario most likely describes allopatric speciation, where a population is divided by a physical barrier, leading to reproductive isolation and the formation of new species due to genetic divergence over time.
What is the disease that involves changes in the nerves and chemicals of the brain leading to memory loss personality changes and complete dependency?
Alzheimer's disease is a neurodegenerative disorder that causes changes in the brain's nerve cells and chemicals, leading to symptoms like memory loss, personality changes, and eventual complete dependency on others for care.
What is Frontal in Geography?
In geography, "frontal" refers to the boundary between two air masses with different temperatures and moisture levels. When a warm air mass meets a cold air mass, a frontal boundary is formed, leading to changes in weather conditions such as the formation of clouds, precipitation, and changes in wind direction.
Scientist break down evolution into which two catorgories?
Scientists typically break down evolution into microevolution, which involves small changes within a population over generations, and macroevolution, which involves larger scale changes leading to the formation of new species.
