Biology

Across

2. nonliving parts of the environment (i.e., temperature,soil,light, moisture, air currents)
5. all autotrophs (plants) trap energy from the sun. Beginning of the food chain
7. Part of the DNA nucleotide sequence is transcribed into a complementary mRNA strand in the cell's nucleus.
11. Make a reaction start faster
12. the three-nucleotide sequence on a mRNA molecule that codes for one amino acid.
13. plant structure that develops into a seed when fertilized.
14. the sticky, receptive surface at the top of a flower’s female reproductive organ where pollen grains land and begin the process of fertilization.where pollen grains land and begin the process of fertilization.
17. part of the plant that supports leaves, flowers, and fruits, transports water and dissolved substances from the roots to other parts of the plant.
19. The fertilized egg that has one set of alleles from mom and one set from dad. It is a diploid cell.
21. unicellular organism without a nucleus or other membrane-bound organelles.
22. the scientific study of interactions between organisms and their environments, focusing on energy transfer. The science of relationships
24. Ingest (eat) food containing the sun’s energy. All Herbivores, Carnivores, Omnivores, Decomposers
26. An organism that receives different genetic information from each parent
27. the photosynthetic cells found in the leaves of plants.
32. regulation of an organism’s internal environment to maintain conditions needed for life.
34. one of a pair of cells that function in the opening and closing of a plant’s stomata by changes in their shape.
35. a change in the nucleotide sequence of an organism’s DNA. This may happen due to an error during replication or exposure to damaging agents.
36. Destruction of an enzyme by temperature or other factors.
37. the plant organ that anchors it into the ground and takes in water and nutrie
38. body system that works to protect the body from infection and disease and includes the skin, mucus, and white blood cells.
40. Also called primary producer, producer, or PLANT. The beginning of a food chain

Down

1. a network of tissues and vessels carrying blood and lymph through the body, including the heart, arteries, veins, and capillaries.
3. The process of burning something
4. the end result of a biological or chemical process, what was made or created.
6. sink Anything that absorbs more carbon from the atmosphere than it releases. Examples include plants, ocean, and soil
8. the mRNA carries genetic information to the ribosomes. The Ribosomes use this information to form proteins. We use a codon chart to help us figure out what proteins are made.
9. short chains of amino acids that are linked together. These join to create proteins.
10. flexible, selectively permeable boundary that helps control what enters and leaves the cell.
15. vascular plant tissue that transports water and dissolved minerals away from the roots through the plant.
16. substance that is able to kill or inhibit the growth of bacteria.
18. The pair of homologous chromosomes that forms in prophase 1 and separates in anaphase 1.
20. all living organisms inhabiting the Earth
23. organism’s reaction to a stimulus (a change in an organism’s environment)
25. the place in which an organism lives out its life
28. the place in which an organism lives out its life
29. the above-ground part of a plant, including stems, leaves, flowers, and fruits, which is responsible for photosynthesis, nutrient transport, and reproduction.
30. the role a species plays in a community; its total way of life
31. unicellular organism with membrane-bound nucleus and organelles
33. One specific trait (written as a letter) inherited in the organism's genes.
39. a tiny opening on the surface of a plant leaf or stem, surrounded by guard cells,which control the exchange of gases like carbon dioxide and oxygen between the plant
