Second Quarter
These are organisms that have the ability to produce their own food. Plants are an example of this.
Autotrophs
The process where plants convert water, carbon dioxide, and minerals to food, with the help of sunlight.
Photosynthesis
The term used to describe the process of transferring the pollen grains from the male reproductive structure to the female reproductive structure of a plant.
Pollination
(parts of a flower)
The cup-like structure found under the flower. It connects the flower to the stem and holds the rest of the flower in place.
sepal
(parts of a flower)
A cluster of sepals is called a _________.
calyx
The _____ is the colorful leaf-like structure surrounding the main reproductive structure of a flower.
petal
(parts of a flower)
A group of petals is called _________.
corolla
(parts of a flower)
The male reproductive part of a flower. It is made up of two main parts, the anther and the filament.
stamen
(parts of a flower)
Two main parts of the stamen.
anther and filament
(parts of a flower)
Part of the stamen where pollen is produced.
anther
(parts of a flower)
Part of the stamen which is the stalk that holds the anther in place.
filament
(parts of a flower)
The fine dust or grain that is actually the male gamete or sex cell of the plant.
pollen

The female organ of a flower.
carpel or pistil
The carpel is composed of the ______ and the _______.
stigma and the style
The “eggs” of plants that develop into seeds.
ovules
It is defined as a flower that possesses both the pistil and the stamen.
complete flower
A flower that has either a pistil or a stamen.
incomplete flower
Plants depend on the process of __________ to produce seeds that grow into new plants.
pollination
This is the transfer of the pollen containing the male gamete from the anther to the stigma of a flower.
pollination
Agents of pollination:
- insects
- birds
- humans
- winds
Flowers wither and die when they are not pollinated. Those that have been pollinated produce what?
fruits
Fruits are classified based on their physical characteristics:
- dry (i.e., nuts and grains)
- fleshy (apples, cherries, cucumbers, grapes, tomatoes, and citrus fruits)
Fruits that form from one ovary.
simple fruits
Fruits that come from several ovaries of just one flower.
aggregate fruits
Fruits that come from combined ovaries of separate flowers.
multiple fruits
Fruits that form only from the ovaries are called _______.
true fruits
Fruits that form from other flower parts, namely the petals, sepals, and stamen are called ____________.
accessory fruits
The science that deals with the study of plants.
botany
