1. Actinomorphic flower and zygomorphic flower:
- Actinomorphic flower: A flower that can be divided into equal halves in any plane, typically with radial symmetry. The floral parts are arranged in a circular or star-like pattern.
- Zygomorphic flower: A flower that can only be divided into equal halves in one specific plane, typically with bilateral symmetry. The floral parts are arranged asymmetrically.
2. Flowering plants and Non-flowering plants:
- Flowering plants: Plants that produce flowers for reproduction. They belong to the group Angiosperms and have seeds enclosed within a fruit.
- Non-flowering plants: Plants that do not produce flowers for reproduction. They include groups such as ferns, mosses, and algae.
3. Bilateral symmetry and radial symmetry:
- Bilateral symmetry: An organism or structure that can be divided into two equal halves along only one plane, resulting in two mirror-image halves. This type of symmetry is commonly found in animals with a distinct front and back, such as insects and mammals.
- Radial symmetry: An organism or structure that can be divided into equal halves in multiple planes, typically with a central axis. This type of symmetry is commonly found in organisms like jellyfish and sea anemones.

1. Actinomorphic Flower vs. Zygomorphic Flower
- Actinomorphic (Radial) Flower:
- Exhibits radial symmetry, with multiple identical planes of symmetry
- Parts are arranged in concentric circles or whorls
- Example: Roses
- Zygomorphic (Bilateral) Flower:
- Exhibits bilateral symmetry, with only one plane of symmetry
- Parts are arranged in mirror-image halves
- Example: Orchids
2. Flowering Plants (Angiosperms) vs. Non-Flowering Plants (Gymnosperms)
- Flowering Plants (Angiosperms):
- Produce seeds enclosed within an ovary
- Have vascular tissues (xylem and phloem)
- Examples: Dicotyledons, Monocotyledons
- Non-Flowering Plants (Gymnosperms):
- Produce naked seeds (not enclosed)
- Have vascular tissues but often less well-developed
- Examples: Conifers, Cycads
3. Bilateral Symmetry vs. Radial Symmetry
- Bilateral Symmetry:
- An object can be divided into two mirror-image halves along a single plane
- Seen in many animals and some flowers (zygomorphic)
- Example: Human body
- Radial Symmetry:
- An object can be divided into multiple identical planes of symmetry
- Seen in many plants (actinomorphic flowers), invertebrates, and marine animals
- Example: Starfish
