Types of Inflorescence
Racemose Inflorescence
In racemose inflorescence, the main axis continues to grow and produces flowers at its tip. This type of inflorescence can be further categorized into:
- Indeterminate: The main axis continues to grow, and the flowers are arranged in an acropetal manner, i.e., the younger flowers are towards the tip.
- Determinate: The main axis terminates in a flower, and the growth ceases. The flowers are arranged in a basipetal manner, i.e., the younger flowers are towards the base.
Cymose Inflorescence
In cymose inflorescence, the main axis terminates in a flower, and the lateral branches also terminate in flowers. This type of inflorescence can be further categorized into:
- Monochasial: The main axis produces only one lateral branch, and the process continues.
- Dichasial: The main axis produces two lateral branches, and the process continues.
Functions of Inflorescence
Inflorescence serves several important functions in plants:
- Reproduction: Inflorescence allows for the production of flowers, which are essential for sexual reproduction in plants.
- Attracting Pollinators: The arrangement and display of flowers in inflorescence help attract pollinators such as bees, butterflies, and birds, facilitating pollination.
- Seed Dispersal: After fertilization, the flowers develop into fruits, which contain seeds. The arrangement of flowers in inflorescence can aid in the dispersal of these seeds.
Study Guide
When studying inflorescence, it is important to focus on the following key points:
- Understanding the different types of inflorescence, including racemose and cymose inflorescence, and their subcategories.
- Identifying the characteristics of each type of inflorescence and being able to differentiate between them.
- Exploring the functions of inflorescence in the reproductive cycle of plants and its role in attracting pollinators and facilitating seed dispersal.
Additionally, it is helpful to study specific examples of plants exhibiting different types of inflorescence and to observe real-life examples of inflorescence in different plant species.

PHYSICAL SCIENCE
Motion and Stability: Forces and Interactions
Explore objects that can be manipulated in order to determine cause-and-effect relationships (e.g., distance between objects affecting strength of a force, orientation of magnets affecting direction of a magnetic force) of electric interactions between two objects not in contact with one another (e.g., force on hair from an electrically charged balloon, electrical forces between a charged rod and pieces of paper) or magnetic interactions between two objects not in contact with one another (e.g., force between two permanent magnets or between an electromagnet and steel paperclips, force exerted by one magnet versus the force exerted by two magnets).
Apply scientific ideas about magnets to solve a problem through an engineering design project (e.g., constructing a latch to keep a door shut, creating a device to keep two moving objects from touching each other such as a maglev system).
