| Fruit | the ripened ovary of a flowering plant |
| Petals | they are the largest and the most noticeable parts of a flower; they are the like-leaves structure of a flower |
| Sepals | they are the green small parts in a flower below the petals |
| Stamens | they are the male reproductive organ in a flower, they are a stem like structure in the center of a flower |
| Anther | it’s a part of the stamen that produces pollen grain |
| Filament | it's another part of the stamen that connects the anther to the plant |
| Pistils | the female reproductive organ in a flower and it's in the center of a flower too |
| Stigma | the top part of the pistils, it's sticky so that it captures the pollen grains that fall on it |
| Style | the middle part of a pistil, it's as tem-like part that connects the stigma to the ovary |
| Ovary | the base part of a pistil and it contains the ovules |
| Ovules | they are inside the ovaries and they contain the egg cell that can develop into seeds if they are fertilized |
| Self-pollination | it occurs by transfer of pollen within the same flower or between different flowers of the same plant |
| Cross-pollination | it occurs by transfer of pollen from the anther of one plant's flower to the stigma of a flower of the same kind of plant |
| Fertilization | the process when the sperm cells from the pollen grains enter the ovules and join the egg cells |
| Nectar | a sweet liquid that is produced by many flowers that some animals use as food, if the flower has a color and/or scent, it's a sign that it has nectar |
| Berry | a type of fruit that has seeds throughout the flesh of a single enlarged ovary, like watermelons, blueberries, and tomatoes |
| Aggregate fruits | it is a type that is made up of many fruitlets, each fruitlet develops from one pistil of a flower of many pistils, Ex strawberry |
| Pome | the type of fruit of which seeds are in its core, the core form from a single flower's parts that surround the ovary, like apples and pears |
| Drupe | it is a kind of fruit that has a single seed with a hard covering, the seed develops from a single pistil of a flower with many pistil, like plums |
| Multiple fruit | it is a type of fruit that is made up of fruitlets that develop from the pistils of several flowers on the same plant, like figs and pineapples |
| Tubers | they are underground stems for some plants that swell (enlarge) to store food, such as potatoes |
| Grafting | it is a form of asexual reproduction that occurs when two parts of two plants are joined to develop a single plant that has the characteristics of both parents |
