DENDROLOGY

Detailed explanation-1: -Answer and Explanation: A flower with 3 sepals, 3 petals, and 6 stamens is considered a monocot. This is because monocots exhibit a predictable arrangement of their flower parts in multiples of three, such as their petals, sepals and stamens.

Detailed explanation-2: -The monocot flowers are trimerous, which means they have either 3 petals or the number of petals are multiple of three, example a monocot plant can have 12 petals as it is a multiple of three.

Detailed explanation-3: -Number of flower parts–If you count the number of petals, stamens, or other floral parts, you will find that monocot flowers tend to have a number of parts that is divisible by three, usually three or six. Dicot flowers on the other hand, tend to have parts in multiples of four or five (four, five, ten, etc.).

Detailed explanation-4: -A. Many showy cultivated plants do indeed have four or five petals, said Melanie Sifton, vice president of horticulture at Brooklyn Botanic Garden, but another big plant category, the monocots, often have three petals or multiples of three. Even then, the numbers and arrangements vary widely.
