Across
- 2. More than one young dog.
- 4. A long, whip-like structure that helps some single celled organisms move. It is composed of microtubules.
- 5. One in which there is a greater concentration or number of solute particles outside a membrane than there are inside it.
- 11. Rod-shaped organelles that can be considered the power generators of the cell, converting oxygen and nutrients into adenosine triphosphate (ATP).
- 13. 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.
- 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.
- 16. Organisms are organisms that consist of more than one cell.
- 17. Are closed sacs, made of membranes with inorganic or organic molecules inside, such as enzymes.
- 20. A chemical reaction that takes place inside a plant, producing food for the plant to survive.
- 22. 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.
- 23. A German physician and physiologist, co-founder of cell theory in animals.
- 25. Are organisms whose cells have a nucleus enclosed within membranes, unlike prokaryotes (Bacteria and Archaea), which have no membrane-bound organelles.
- 28. The integumentary, muscular, skeletal, nervous, circulatory, lymphatic, respiratory, endocrine, urinary/excretory, reproductive and digestive
- 29. A group of cells that have similar structure and that function together as a unit.
- 31. An individual animal, plant, or single-celled life form.
- 32. Transport A movement of ions and other atomic or molecular substances across cell membranes without need of energy input.
- 33. The body's recognizable structures (for example, the heart, lungs, liver, eyes, and stomach) that perform specific functions.
Down
- 1. 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.
- 3. The action of magnifying something or the process of being magnified.
- 6. 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.
- 7. Less than—to the cell, and the net flow of water will be into the cell.
- 8. A German botanist and co-founder of cell theory in plants.
- 9. 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.
- 10. Do not have cell walls or chloroplasts, the organelle that carries out photosynthesis
- 12. The smallest particle of a chemical element that can exist.
- 14. A group of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction.
- 18. Organelles found in plant cells and eukaryotic algae that conduct photosynthesis.
- 19. An organism that consists of a single cell.
- 21. 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.
- 24. The movement of a substance from an area of high concentration to an area of low concentration.
- 26. 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.
- 27. Basic unit of life.
- 30. A microscopic protozoan that can be found in freshwater and saltwater environments.
