Plants with Unisexual Flowers

Plants can have either bisexual flowers (containing both male and female reproductive structures) or unisexual flowers (containing either male or female reproductive structures). Among the plants you mentioned, several have unisexual flowers. Let's go through each one:

1. Alder (Olha): Alder trees (Alnus spp.) have separate male and female flowers on the same tree. The male flowers produce pollen, while the female flowers develop into cones.

2. Watermelon (Arbuz): Watermelon plants (Citrullus lanatus) have separate male and female flowers. The male flowers produce pollen, while the female flowers develop into the fruit.

3. Burdock (Lopukh): Burdock (Arctium spp.) is a biennial plant with separate male and female flowers. The male flowers produce pollen, while the female flowers develop into burrs containing the seeds.

4. Rye (Rozh): Rye (Secale cereale) is a cereal grain with separate male and female flowers. The male flowers produce pollen, while the female flowers develop into grains.

5. Cucumber (Ogurets): Cucumber plants (Cucumis sativus) have separate male and female flowers. The male flowers produce pollen, while the female flowers develop into the fruit.

6. Apple (Yablonya): Apple trees (Malus domestica) have flowers with both male and female reproductive structures, making them bisexual flowers.

7. Cabbage (Kapusta): Cabbage (Brassica oleracea) is a biennial plant with separate male and female flowers. The male flowers produce pollen, while the female flowers develop into seeds.

8. Eggplant (Baklazhan): Eggplant (Solanum melongena) has bisexual flowers, meaning they contain both male and female reproductive structures.

9. Hops (Khmel): Hops (Humulus lupulus) have separate male and female flowers on different plants. The female flowers develop into cones, which are used in brewing.

10. Aspen (Osina): Aspen trees (Populus tremula) have separate male and female flowers on the same tree. The male flowers produce pollen, while the female flowers develop into capsules containing the seeds.

11. Chamomile (Romashka): Chamomile (Matricaria chamomilla) has bisexual flowers, meaning they contain both male and female reproductive structures.

To summarize, among the plants you mentioned, the ones with unisexual flowers are alder, watermelon, burdock, rye, cucumber, cabbage, hops, and aspen. Apple and chamomile have bisexual flowers, while eggplant has bisexual flowers as well.
