Across
- 3. :the act of transferring pollen grains from the male anther of a flower to the female stigma.
- 4. :the fusion of haploid gametes, egg and sperm, to form the diploid zygote
- 7. :have seeds that use water as a means of dispersal. The seeds float away from the parent plant.
- 10. :that run through their stems and roots :the part of a plant which attaches it to the ground or to a support
- 11. : a central component of chlorophyll which is supporting the function to absorb sunlight during photosynthesis. Magnesium acts as a phosphorus carrier in plants and is essential for phosphate metabolism.
- 15. :the spongy mesophyll layer they allow the diffusion of carbon dioxide and oxygen. Stomata (small pores usually found on the lower surface of the leaf)which allows carbon dioxide and oxygen to enter and leave the leaf.
- 17. :contains the male gametes of the flower.
- 18. :is a space in a cell filled with fluid in the form of a membrane-covered cavity (tonoplast).
- 19. :is a sweet,sugar liquid that flowers produce from plants when they bloom to attract pollinators such as insects.
- 20. :The xylem parenchyma tissue cells function to store food reserves.
- 21. :the processes of evaporation and transpiration.It can also refer to direct evaporation of liquid water from the leaf surface of the plant.
- 22. :the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
- 25. :the nuclei of the two gametes have joined together,they form a new cell.
- 26. :A young, developing plant, such as the rudimentary plant inside the seed of higher plants or that inside the archegonium of mosses and ferns.
Down
- 1. :the most colourful part of the flower,they attract insects or birds to the flower.
- 2. :made in the anthers of flowers,it contains in the male gametes.
- 5. :the central and most important part of an object, movement, or group, forming the basis for its activity and growth.
- 6. : which is needed to make proteins for healthy growth. Plants absorb nitrates in water through their roots. Nitrates are present at high levels in plant fertilizers. Without nitrates, the amount of chlorophyll in leaves reduces.
- 8. : a pair of guard cells similar to two curved sausages. Inland plants, there are many stomata on the underside of the leaves, while in plants that live in water, stomata are found on the upper surface of the leaves.
- 9. :is the movement, spread or transport of seeds away from the parent plant.
- 12. :a flowering plant's unit of reproduction, capable of developing into another such plant.
- 13. : The enlarged basal portion of the pistil where ovules are produced.
- 14. : chemical substances supplied to the crops to increase their productivity. These are used by the farmers daily to increase the crop yield. The fertilizers contain the essential nutrients required by the plants, including nitrogen, potassium, and phosphorus.
- 16. :typically stored as long polymers of glucose molecules with glycosidic bonds for structural support example chitin, cellulose
- 23. :it is something inside the female gametes,which is inside the ovary
- 24. :part of the pistil where pollen germinates.
