Study Notes

Ovary Positions in Flowers

Ovary positions referred to as 'superior' (above attachment of other floral parts) and 'inferior' (below attachment of other floral parts).

Flower Symmetry

Radial symmetry in flowers is also known as 'actinomorphic symmetry'.
Bilateral symmetry in flowers is referred to as 'zygomorphic symmetry'.

Types of Flowers

Complete flowers contain all four main parts: sepals, petals, stamens, and pistils.
Incomplete flowers lack one or more of the sepals, petals, stamens, or pistils.
Perfect flowers contain both male (stamens) and female (pistils) reproductive structures.
Imperfect flowers contain either male or female reproductive structures, but not both.

Plant Types

Monoecious plants have both male and female flowers on the same plant.
Dioecious plants have male flowers on one plant and female flowers on another.

Pollination

Hermaphroditic plants possess flowers that contain both male and female parts.
Pollination can be facilitated by various vectors including wind, water, and animals.

Flower Structure

Flower parts include the calyx (sepals), corolla (petals), stamens (male), and pistils (female).
The collective noun for the corolla and calyx is 'perianth'.
The collective noun for all the stamens is 'androecium'.
The three parts that make up a pistil are the ovary, style, and stigma.

Placentation

Placentation refers to the arrangement of ovules within the ovary.
Axile placentation occurs when ovules are attached to the central column of the ovary.
Basal placentation occurs when ovules are attached at the base of the ovary.

Floral Terms

Connation is the fusion of similar floral parts (e.g., petals).
Adnation is the fusion of different floral parts (e.g., stamens with petals).
Connation differs from adnation in that it involves similar parts while adnation involves different parts.
