BIOLOGY

2. : The jelly-like substance that fills the inside of a cell
7. : The basic unit of life
8. : A type of cell that lacks a nucleus and membrane-bound organelles
9. : A biological community of interacting organisms and their physical environment
10. : Organelle in plant cells that is the site of photosynthesis
12. : A proposed explanation for a phenomenon, which can be tested
15. : The process of nuclear division in eukaryotic cells that results in two daughter nuclei each having the same number and kind of chromosomes as the parent nucleus
17. : Genetic material in cells
20. : A protein that acts as a biological catalyst
22. : Organisms that consume other organisms for energy
23. : A thread-like structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes

1. : A membrane-bound sac that plays roles in intracellular digestion and the release of cellular waste products
3. : An organism that makes its own food
4. : Structures responsible for protein synthesis
5. : The study of heredity and the variation of inherited characteristics
6. : The movement of water across a selectively permeable membrane
11. : A group of similar cells that perform the same function
13. : The process by which plants use sunlight, water, and carbon dioxide to create their own food
14. : Organelles known as the "powerhouse" of the cell, where cellular respiration occurs
16. : The control center of a cell, containing genetic material
18. : A group of living organisms consisting of similar individuals capable of exchanging genes or interbreeding
