Cells

5. a dense organelle present in most eukaryotic cells, typically a single rounded structure bound by a double membrane, containing the genetic material
6. the semipermeable membrane surrounding the cytoplasm of a cell
10. organelle found only in plant cells and some protists such as algae; animal cells do not have these; work to convert light energy of the Sun into sugars that can be used by cells
11. a member of a large group of unicellular microorganisms that have cell walls but lack organelles and an organized nucleus, including some that can cause disease
12. The jellylike material that makes up much of a cell inside the cell membrane, and, in eukaryotic cells, surrounds the nucleus. The organelles of eukaryotic cells, such as mitochondria, the endoplasmic reticulum, and (in green plants) chloroplasts, are contained in this

1. consists of an outer membrane, an inner membrane and a gel-like material called the matrix; functions to convert sugars into energy the cell can use
2. any of a number of organized or specialized structures within a living cell
3. sphere-shaped structure within the cytoplasm of a cell that is composed of RNA and protein and is the site of protein synthesis; are free in the cytoplasm and often attached to the membrane of the endoplasmic reticulum; exist in both eukaryotic and prokaryotic cells
4. Eukaryotic cell containing membrane-bound organelles without a cell wall or chloroplasts
7. Inside a cell, organelle that functions to remove wastes; one of the key organelles involved in digestion and waste removal; organelles that contain digestive enzymes; digest excess or worn out organelles, food particles, and engulfed viruses or bacteria
8. Network of fibers composed of proteins contained within a cells cytoplasm
9. cell that is a structural and functional unit of a plant
