Answer:
- 1. An inflorescence is a group or cluster of flowers arranged on a stem that is composed of a main branch or a complicated arrangement of branches. Morphologically, it is the modified part of the shoot of seed plants where flowers are formed. ... The stalk of each single flower is called a pedicel.
- 2. Petal is the part of the flower which is the non-essential whorls that are brightly colored to attract insects for pollination process.
- Petaloid is when the perianth is non-green i.e. when petals and sepals appear to be undifferentiated. Petaloid is resembling the petal of a flower.
- Example, Michelia sps
- 3. Types of androecium in flowers: Polyandrous: When the stamens of a flower are free, the condition is called polyandrous. ... Polyadelphous: When the filaments of anthers in a flower are fused into more than two groups, the condition is called polyadelphous.
