cells and organelles

5. The absence of polarity makes them not interact with water.
6. – Cell division forming two identical cells. Used for growth and tissue repair.
9. – Simple cells without a nucleus, like bacteria. DNA is found in the cytoplasm.
11. – Builds proteins from amino acids. Found in the cytoplasm or on the endoplasmic reticulum.
13. A cellular structure involved in the process of cell division.
14. – Controls cell activities and contains DNA. It regulates growth, metabolism, and reproduction.
15. – Basic units of life that perform essential functions. They can exist independently or as part of multicellular organisms.
18. – Movement of molecules from high to low concentration. It helps substances cross cell membranes.
19. – Produces energy (ATP) through cellular respiration. Known as the cell’s powerhouse.
20. APPARATUS A series of flattened sacs that sort and package cellular materials.

1. Membrane enclosed organelles that contain an array of enzymes capable of breaking down all types of biological polymers.
2. – Cell division producing four unique cells with half the chromosomes. Essential for sexual reproduction.
3. a complex of DNA, proteins, and RNA that makes up the genome in eukaryotic cells.
4. – Complex cells with a nucleus and organelles. Found in animals, plants, fungi, and protists.
7. PROTEIN It move molecules across a membrane within a cell. Responsible for moving materials into and out of the cell.
8. Folds in the inner mitochondrial membrane. Increase the surface area of the mitochondrial membrane.
10. Specialized structures within cells that perform specific functions.
12. – Movement of water from high to low concentration. Occurs through a selectively permeable membrane.
16. MEMBRANE An outermost envelope-like membrane or a structure. Controls the entry and exit of substances.
17. These molecules easily interact with and dissolve in water.
