Y10 Biology

1. - Long filaments of a fungus that contain many nuclei.
3. - A rod-shaped species of bacterium used to produce yoghurt from milk.
4. -Found in the center of a flower and helps to collect pollen.
5. - A type of cell found in plants and animals that contains a nucleus.
8. - The basic building block of all living organisms.
11. - Pathogenic protoctists that cause malaria.
13. - A partially permeable barrier that surrounds the cell.
14. - A type of cell found in bacteria that does not a nucleus.
16. - A protoctist that has features similar to plant cells e.g. chloroplasts.
17. - A multicellular fungus that has a hyphal structure.
19. - An infection virus that causes influenza (the flu).
20. - A collection of thread-like hyphae in a fungus.

2. - An infectious virus that weakens the immune system and can lead to AIDS (acquired immunodeficiency syndrome).
6. - Microorganisms that cause infectious disease.
7. - A spherical, pathogenic bacterium that causes pneumonia.
9. - An organelle which is the site of photosynthesis.
10. - Protoctists that live in pond water and resemble animal cells.
11. - An endothermic reaction in which energy is transferred from the environment to the chloroplasts by light.
12. - A double-stranded polymer wound to form a double helix. It carries the genetic code.
15. - An outer, structural layer that surrounds some cells. In plant cells, it is made of cellulose. In fungi, it is made of chitin.
18. - Loops of DNA found in the cytoplasm of prokaryotic cells.
