Complete Flowers - have all four parts of the flower present:  sepals, petals, pistil, and stamens   *complete flowers are "perfect flowers"......but not all "perfect flowers" are complete flowers   *if the petals, or sepals are missing, the flower may still be perfect if the pistil and stamens are present   *but if the petals or sepals are missing.......the flower is not considered a complete flower

The calyx is the part of the flower has sepals. They are usually green and their purpose is to protect the flower bud until it is ready to bloom. Flowers have different numbers of sepals just as they can have different numbers of petals. When flowers produce sepals and other flower parts in threes or multiples of three, they are monocots. When the flower produces in fours and fives or multiples of four and five, they are called dicots.

The corolla is the collective term for the petals of a flower. Together, the sepals and corolla are called the perianth. Since neither part is directly used in reproduction, they are considered accessory parts. Meanwhile, the petals of a flower may look very much like sepals. If so, the sepals and petals are called tepals. A large and showy corolla is a sign that the flower uses creatures instead of wind to help it pollinate and thereby reproduce. The color can even help tell you what kinds of creatures the flower is trying to entice with its petal display. Bees, for instance, are attracted to yellow and bright blue.

Androecium- The androecium is the male part of a plant and is made up of stamens. In turn, stamens are made up of an anther and a supporting filament, which looks like thin stems within the flower. The filament carries nourishment up to the anther, which has sacs that make the pollen. The anther may be lobed or singular. The filament may be attached to the anther at its base or between the lobes. In flowers that are wind-pollinated, the anthers tend to produce a lot of pollen.

The middle whorl at the inside of a complete flower is the gynoecium, the female reproductive component. Carpels make up the gynoecium, these united to form a singular pistil or sections of pistils. The pistil looks similar to a wine bottle, with the bottom containing the ovary and ovules, which, when fertilized, eventually make seeds. The ovaries can become fruit that contain seeds. Moving up the pistil from the bottom, you find the style, this supporting a stigma. When pollen finds the stigma, pollination occurs.

Four parts of a flower -> arranged in rings inside each other.

Sepal - Protected the flower when it was in bud. The sepal is often green.

Stamen - The male part of the plant which produces the pollen (yellow, dust like). (anthers -> tops of stamen, filaments -> bottom part)

Petals - Brightly coloured in insect pollinated plants. Small (or non-existent) in wind pollinated plants.

Carpel -The female part of the plant which produce fruit once pollination has taken place. The fruit contains seeds. (Carpels. stigma -> top where it gets pollen, style -> pollen travels down, ovary -> where fruit is formed)

Bisexual flower showing all 4 characteristic parts which are technically modified leaves: Sepal, petal, stamen & pistil. This flower is referred to as complete (with all 4 parts) and perfect (with "male" stamens and "female" pistil). The ovary ripens into a fruit and the ovules inside develop into seeds. Most flowers contain several to many ovules. Incomplete flowers are lacking one or more of the 4 main parts. Imperfect (unisexual) flowers contain a pistil or stamens, but not both. Species populations with male and female flowers borne on separate male and female individuals are termed dioecious. Species populations with separate male on female flowers borne on the same individuals are termed monoecious.

FLOWER TYPES BASED ON PARTS PRESENT complete - contains all floral parts, i.e. sepals, petals, stamens and pistils incomplete - lacks one or more of the floral parts perfect  - contains both pistils and stamens (may or may not have sepals or petals) imperfect   - lacks either pistils or stamens (may or may not have sepals or petals) pistillate - contains only pistils (may or may not have sepals or petals) staminate -contains only stamens (may or may not have sepals or petals) sterile    - both stamens and pistils are absent, or are non-functional
