Question

1.secifically, where are pollen grains produced in the mail reproductive organ? Specifically, where are the egg cells made in the female reproductive organ? By which nuclear process (i.e., mitosis or meiosis) are these gametes formed?

2. Seeds come from which part of the flower? Fruit is what part of the flower? The embryo comes from which part of the flower?

3. Which was taller, the stamen or the carpel? Is this important? Why or why not?
INFO -

Stamen – 1.75 inches

Carpel – 3.75 inches

Estimated number of ovules = 6

4. SOURCE OF NUTRITION -

Nonvascular plants

(e.g., mosses)

Seedless vascular plants

(e.g., ferns)

Gymnosperms

Angiosperms

Answer 1

1. The anther in stamen produces the male reproductive organs i.e. pollen grains. The carpel in the pistil produces egg, the female reproductive organs in plant. Plants make use of meiosis to produce spores.

2. Seeds are formed when pollen comes in contact with ovules through pollination.The ovules in the ovary form seeds. It is the female reproductive structure of flower that develops into the fruit. Fruit is a ripened ovary of the plant.

3. Carpel is taller so that they can attract the pollens drifting in the wind and ensure pollination for its survival.

4. Mosses derive their nutrition through the photosynthetic activity of the chlorophyll pigments in the chloroplasts. Ferns produce fronds which are photosynthesis enabled. Gymnosperms and Angiosperms are photosynthetic too.
