Across
- 4. is the smallest structural and functional unit of an organism, typically microscopic and consisting of cytoplasm and a nucleus enclosed in a membrane. Microscopic organisms usually consist of a single cell, either eukaryotic or prokaryotic.
- 6. is a membraneous organelle that has a large surface area covered in ribosomes. The rough endoplasmic reticulum location is continuous with the nuclear membrane around the nucleus
- 8. the study of living organisms, divided into many specialized fields that cover their morphology, physiology, anatomy, behavior, origin, and distribution.
- 9. the gelatinous liquid that fills the inside of a cell. It is composed of water, salts, and various organic molecules. Some intracellular organelles, such the nucleus and mitochondria
- 12. also called the plasma membrane, is found in all cells and separates the interior of the cell from the outside environment. The cell membrane consists of a lipid bilayer that is semipermeable. The cell membrane regulates the transport of materials entering and exiting the cell
Down
- 1. central and most important part of an object, movement, or group, forming the basis for its activity and growth.
- 2. without surface ribosomes is not involved in protein synthesis. Its main function is the synthesis of lipids, steroids, and carbohydrates, as well as the metabolism of exogenous substances, such as drugs or toxins.
- 3. your microscope has a mechanical stage, you will be able to move the slide around by turning two knobs. One moves it left and right, the other moves it up and down.
- 5. a complex of vesicles and folded membranes within the cytoplasm of most eukaryotic cells, involved in secretion and intracellular transport.
- 7. 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)
- 10. any cell or organism that possesses a clearly defined nucleus
- 11. any organism that lacks a distinct nucleus and other organelles due to the absence of internal membranes.
