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.
