Across
- 1. The smallest particle of a chemical element that can exist.
- 5. Rod-shaped organelles that can be considered the power generators of the cell, converting oxygen and nutrients into adenosine triphosphate (ATP).
- 7. A chemical reaction that takes place inside a plant, producing food for the plant to survive.
- 14. Organisms are organisms that consist of more than one cell.
- 15. The extracellular fluid has the same osmolarity as the cell, and there will be no net movement of water into or out of the cell.
- 17. A type of biological or synthetic, polymeric membrane that will allow certain molecules or ions to pass through it by diffusion—or occasionally by more specialized processes of facilitated diffusion, passive transport or active transport.
- 19. More than one young dog.
- 20. Eukaryotic cells present in green plants, photosynthetic eukaryotes of the kingdom Plantae.
- 22. Are closed sacs, made of membranes with inorganic or organic molecules inside, such as enzymes.
- 24. Are organisms whose cells have a nucleus enclosed within membranes, unlike prokaryotes (Bacteria and Archaea), which have no membrane-bound organelles.
- 26. So small as to be visible only with a microscope.
- 30. Respiration of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products.
- 31. A type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell, as in the production of gametes and plant spores.
- 32. Do not have cell walls or chloroplasts, the organelle that carries out photosynthesis
- 33. A group of cells that have similar structure and that function together as a unit.
- 34. Less than—to the cell, and the net flow of water will be into the cell.
Down
- 2. The action of magnifying something or the process of being magnified.
- 3. The process of particles, which are sometimes called solutes, moving through a solution or gas from an area with a higher number of particles to an area with a lower number of particles.
- 4. An individual animal, plant, or single-celled life form.
- 6. The integumentary, muscular, skeletal, nervous, circulatory, lymphatic, respiratory, endocrine, urinary/excretory, reproductive and digestive
- 8. The movement of a substance from an area of high concentration to an area of low concentration.
- 9. Transport A movement of ions and other atomic or molecular substances across cell membranes without need of energy input.
- 10. An organism that consists of a single cell.
- 11. A long, whip-like structure that helps some single celled organisms move. It is composed of microtubules.
- 12. Process by which DNA makes a copy of itself during cell division.
- 13. One in which there is a greater concentration or number of solute particles outside a membrane than there are inside it.
- 16. Theory that living organisms are made up of cells, that they are the basic structural/organizational unit of all organisms, and that all cells come from pre-existing cells.
- 18. The spontaneous net movement of solvent molecules through a selectively permeable membrane into a region of higher solute concentration, in the direction that tends to equalize the solute concentrations on the two sides.
- 21. Organelles found in plant cells and eukaryotic algae that conduct photosynthesis.
- 23. A microscopic protozoan that can be found in freshwater and saltwater environments.
- 25. A group of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction.
- 26. A type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth.
- 27. A German physician and physiologist, co-founder of cell theory in animals.
- 28. Basic unit of life.
- 29. A German botanist and co-founder of cell theory in plants.
- 35. The body's recognizable structures (for example, the heart, lungs, liver, eyes, and stomach) that perform specific functions.
