Biology

5. They are produced in the anthers of flowers, and they contain male gametes. They can be taken from anther to stigma in pollination.
6. Production of an mRNA molecule on DNA.
8. It contains an upper layer of palisade cells and a lower layer of spongy cells with large air spaces. The tissues in the centre of leaf, where photosynthesis takes place.
9. A plant tissue that conducts water and mineral salts from the roots to all other parts, provides mechanical support, and forms the wood of trees and shrubs.
10. The division of a nucleus into two so that the two daughter cells have exactly the same number and type of chromosomes as the parent cell.

1. An organelle found in some plant cells, which contains chlorophyll and where photosynthesis takes place.
2. The contents of a cell, excluding the nucleus.
3. We usually use iodine solution to detect it. And the polysaccharide that is used as an energy store in plant cells.
4. When male gametes fuse with female gametes, the diploid cell produced .
7. The chemical reactions in cells that break down nutrient molecules(organic compounds) and release energy for metabolism.
