Cell and Organelles

4. are major components of the cytoskeleton.
8. the organelle that uses the energy of sunlight to make food. It contains the chlorophyll which help green plant cell trap the sun’s energy and produce food.
9. the organelle in which amino acids are hooked together to make proteins
10. is a cellular structure involved in the process of cell division. Before cell division, the centrosome duplicates and then, as division begins, the two centrosomes move to opposite ends of the cell.
13. are small, membrane-enclosed organelles (Figure 10.24) that contain enzymes involved in a variety of metabolic reactions, including several aspects of energy metabolism.
14. the organelle that breaks down food molecules to make ATP
16. refers to a mixture of DNA and proteins that form the chromosomes found in the cells of humans and other higher organisms.
17. hairlike structure
18. are paired barrel-shaped organelles located in the cytoplasm of animal cells near the nuclear envelope.

1. the organelle that digests food particles, wastes, cell parts, and foreign invade
2. in biology, the thin layer that forms the outer boundary of a living cell or of an internal cell compartment.
3. the organelle that stores water and other material
5. helps prokaryotes cling to each other and to various surfaces in their environment, and also helps prevent the cell from drying out.
6. “bridges” between two plant cells that separate the outer cell membranes of the plant cells.
7. are thread-like structures located inside the nucleus of animal and plant cells.
10. is the basic unit of life
11. also called actin filaments, are protein filaments in the cytoplasm of eukaryotic cells that form part of the cytoskeleton.
12. a membrane which bounds the chief vacuole of a plant cell.
15. is a spherical structure found in the cell's nucleus whose primary function is to produce and assemble the cell's ribosomes.
18. is the network of fibres forming the eukaryotic cells, prokaryotic cells and archaeans.
