The body of the ovule is fused within the funicle at :
1. | Micropyle | 2. | Nucellus |
3. | Chalaza | 4. | Hilum |
The ovule of an angiosperm is technically equivalent to:
1. megasporangium
2. megasporophyll
3. megaspore mother cell
4. megaspore
What is the direction of the micropyle in the anatropous ovule:
1. | Upward | 2. | Downward |
3. | Right | 4. | Left |
