Answer 1

Explanation:

Hope the answer is correct

Answer 2

Answer:

Pollen grains - Pollen is a powdery substance consisting of pollen grains which are male microgametophytes of seed plants, which produce male gametes.

Male gamete - The male gametes of angiosperms consist of two sperm cells within a pollen grain or a pollen tube. They are derived from a single generative cell, which is formed as the smaller cell by unequal cell division in the microspore after meiosis.

Pollen tube - A pollen tube is a tubular structure produced by the male gametophyte of seed plants when it germinates. Pollen tube elongation is an integral stage in the plant life cycle.

Ovary - Ovary, in botany, enlarged basal portion of the pistil, the female organ of a flower. The ovary contains ovules, which develop into seeds upon fertilization. The ovary itself will mature into a fruit, either dry or fleshy, enclosing the seeds.

Female gamete - Male gametes are sperm. Female gametes are eggs or ova. The plant life cycle has mitosis occurring in spores, produced by meiosis, that germinate into the gametophyte phase. Gametophyte size ranges from three cells (in pollen) to several million (in a "lower plant" such as moss).

Here is the diagram of a pistil which will help you to understand it!!
