1) What is a flower? Or Define flower.
- A flower is a modified condensed shoot which is a beautiful, reproductive organ of angiosperms that serves the purpose of attracting pollinators.
2) Name the essential whorl of a flower.
- Androecium and Gynoecium.
3) Name the non-essential whorl of a flower
- Calyx and Corolla.
4) Name the male reproductive part of a flower.
- Androecium.
5) Name the female reproductive part of a flower.
- Gynoecium.
6) Name the unit of Androecium.
- Stamens.
7) Name the unit of Gynoecium.
- Carpel / Pistil.
8) Name the parts of the stamen.
- Anther, filament, connective.
9) Name the parts of the pistil.
- Style, stigma and ovary.
10) What are locules?
- A locule or loculus is a small cavity or compartment within an organ or part of an organism. In angiosperms, the term locule usually refers to a chamber within an ovary of the flower and fruits.
11)How many types of ovary occur based on the number of locules?
- Depending on the number of locules in the ovary, fruits can be classified as uni-locular (unilocular), bi-locular, tri-locular or multi-locular.
12) What is unilocular condition? Give an example.
- Unilocular ovaries refers to those ovaries which consists of a single locule. Pea , Bean
13)What is Bilocular Condition? Give an example.
- Bilocular ovaries refers to those ovaries which consists of two locules. Datura
14)What is trilocular condition. Give an example.
- Trilocular ovaries refers to those ovaries which consists of three locules. Coconut, Onion
15)What is tetralocular condition? Give an example.
- Tetralocular ovaries refers to those ovaries which consists of four locules. Mustard
16)What is pentalocular condition? Give an example.
- Pentalocular ovaries refers to those ovaries which consists of five locules. Hibiscus
17)What is placentation?
- Placentation refers to the arrangement of ovules within the ovary. Ovules are attached to ovarian walls through special structures called as placenta.
18)Mention the types of Placentation
- Placentation can be marginal, axile, parietal, basal, free central or superficial in position.
19)What is marginal placentation? Give an example.
- The ovules develop in rows near the margin on the placenta formed along the ventral suture. Pea, Bean. (Legumes)
20)What is Axile placentation? Give an example.
- The placenta develops from the central axis which correspond to the confluent margins of carpels. Tomato, orange, Hibiscus, datura.
21)What is parietal placentation? Give an example
- The placenta is formed by the swelling up of cohering margins, and on the latter develop the ovules in rows. Mustard
22)What is free central placentation? Give an example
- The placenta develop in the centre of the ovary as a prolongation of floral axis and the ovules are attached on this axis. Chilly
23)What is Basal Placentation? Give an example.
- The placenta develops directly on the thalamus and bears a single ovule at the base of the unilocular ovary. Maize, Sunflower
