Biology

2. A cell structure that forms a maze of passageways in which proteins and other materials are carried from one part of the cell to another.
5. a molecule that can be bonded to other identical molecules to form a polymer
7. A unicellular organism that lacks a nucleus and membrane bound organelles
9. basic unit of matter
10. produces ribosomes
11. macromolecule containing hydrogen, oxygen, nitrogen, carbon, and phosphorus examples include DNA and RNA, monomers are nucleotides
14. organelles that capture the energy from sunlight and convert it into chemical energy in a process called photosynthesis
15. site of protein synthesis
17. Energy-rich organic compounds, such as fats, oils, and waxes, that are made of carbon, hydrogen, and oxygen, monomers are glycerol and fatty acids.
18. the study of organisms

1. cell organelle filled with enzymes needed to break down certain materials in the cell
3. A type of protein that speeds up a chemical reaction in a living thing, end in ase example :lactase
4. A system of membranes that modifies and packages proteins for export by the cell
5. A group of atoms bonded together
6. the starches and sugars present in foods, monomers are glucose
7. macromolecule that contains carbon, hydrogen, oxygen, and nitrogen; needed by the body for growth and repair, monomers are amino acids
8. Powerhouse of the cell, organelle that is the site of ATP (energy) production
12. A part of the cell containing DNA and responsible for growth and reproduction, only in eukaryotic cells
13. A long molecule consisting of many similar or identical
16. A cell that contains a nucleus and membrane bound organelles
