Across
- 1. is the cell formed when two gametes fuse during fertilization.
- 4. Taxonomy is the branch of biology that classifies all living things.
- 6. is a diploid organism with two alleles, each of a different type.
- 8. is the biochemical pathway which converts the energy of light into the bonds of glucose molecules.
- 11. are the building blocks of polypeptides and proteins and play important roles in metabolic pathway, gene expression, and cell signal transduction regulation.
- 14. the study of taxonomy
- 17. track reproductive cells (gametes) as they progress through fertilization, become a single-celled zygote, then an embryo, all the way to a fully functioning organism.
- 19. maintains internal order within the body by coordinating the activities of muscles and organs, receives input from sense organs, trigger reactions, generating learning and understanding, and providing protection from danger.
- 20. is a tiny pore in the surface of a leaf that is used for gas exchange.
- 21. describes the complex systems that allow water to move across the Earth and atmosphere.
- 22. is necessary for the production of proteins, the regulation, metabolism, and reproduction of the cell.
Down
- 2. is the code our body uses to convert the instructions contained in our DNA the essential materials of life.
- 3. is the branch of biology that classifies all living things.
- 5. is the process by which male and female gametes are fused together, initiating the development of a new organism.
- 7. is the longest stage in the eukaryote cell cycle. During interphase, the cell acquires nutrients, creates and uses proteins and other molecules, and starts the process of cell division by replicating the DNA.
- 9. is an organelle in cells which functions to hold various solutions or materials.
- 10. are defined as interactions between organisms of two different species, in which each organism benefits from the interaction in some way.
- 12. is a single individual, or being.
- 13. are specialized vesicles within cells that digest large molecules through the use of hydrolytic enzymes.
- 15. a cycle of stages that cells pass through to allow them to divide and produce new cells.
- 16. is a type of tissue in vascular plants that transports water and some nutrients from the roots to the leaves.
- 18. are single-celled microorganisms with prokaryotic cells, which are single cells that do not have organelles or a true nucleus and are less complex than eukaryotic cells.
