- 3. a unit of heredity that is transferred from a parent to offspring and is held to determine some characteristic of the offspring.
- 4. an organelle in the cytoplasm of eukaryotic cells containing degradative enzymes enclosed in a membrane.
- 6. a space or vesicle within the cytoplasm of a cell, enclosed by a membrane and typically containing fluid.
- 9. the smallest structural and functional unit of an organism, typically microscopic and consisting of cytoplasm and a nucleus enclosed in a membrane.
- 11. the central and most important part of an object, movement, or group, forming the basis for its activity and growth.
- 13. a group of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction.
- 16. apparatus: a complex of vesicles and folded membranes within the cytoplasm of most eukaryotic cells, involved in secretion and intracellular transport.
- 19. any of a class of nitrogenous organic compounds that have large molecules composed of one or more long chains of amino acids and are an essential part of all living organisms, especially as structural components of body tissues such as muscle, hair, etc., and as enzymes and antibodies.
- 22. an organelle found in large numbers in most cells, in which the biochemical processes of respiration and energy production occur. It has a double membrane, the inner layer being folded inward to form layers (cristae).
- 24. Acids: a complex organic substance in living cells, especially DNA or RNA, whose molecules consist of many nucleotides linked in a long chain.
- 25. having to do with the skeletal system
- 26. having long, thin lines
- 28. any large group of organic compounds that includes sugars, starch, and cellulose, containing hydrogen and oxygen in the same ratio as water (2:1) and used as structural materials and for energy storage within living tissues.
- 32. A part of the body that performs a specific function
- 33. any of a class of organic compounds that are fatty acids or their derivatives and are insoluble in water but soluble in organic solvents. They include many natural oils, waxes, and steroids.
- 34. The fluid inside a cell but outside the cell's nucleus. Most chemical reactions in a cell take place in the cytoplasm.
Down
- 1. something having many related parts that function together as a whole
- 2. an organelle near the nucleus of a cell that contains the centrioles (in animal cells) and from which the spindle fibers develop in cell division.
- 5. tissue that connects, supports, binds, or separates other tissues or organs, typically having relatively few cells embedded in an amorphous matrix, often with collagen or other fibers, and including cartilaginous, fatty, and elastic tissues.
- 7. apparatus/body: helps process and package proteins and lipid molecules, especially proteins destined to be exported from the cell.
- 8. a minute particle consisting of RNA and associated proteins found in large numbers in the cytoplasm of living cells. They bind messenger RNA and transfer RNA to synthesize polypeptides and proteins.
- 10. membrane: the semipermeable membrane surrounding the cytoplasm of a cell.
- 12. A bundle of fibers that receives and sends messages between the body and the brain
- 14. (Visceral): having an even and regular surface or consistency
- 15. any of the distinct types of material of which animals or plants are made, consisting of specialized cells and their products.
- 17. any of a number of organized or specialized structures within a living cell.
- 18. A body tissue consisting of long cells that can contract and produce motion.
- 20. done contrary to or without choice
- 21. done or brought about of one’s own will
- 23. striated: smooth and devoid of striations
- 27. reticulum: a network of membranous tubules within the cytoplasm of a eukaryotic cell, continuous with the nuclear membrane. It usually has ribosomes attached and is involved in protein and lipid synthesis.
- 29. relating to or denoting the thin tissue forming the outer layer of a body's surface and lining the alimentary canal and other hollow structures.
- 30. situated near or acting on the heat
- 31. small dense spherical structure in the nucleus of a cell during interphase.
