- 1. Jelly-like substance in the cell containing all the organelles in the cell. It helps to maintain the structure of the cell.
- 2. Organelle that contains digestive chemicals that break down food, cell waste, and foreign particles that enter the cell (i.e. viruses and bacteria). It digests and destroys dead cells and old cell parts and recycles material to make other cells.
- 4. The cell’s packaging, sorting, and distributing organelle. They sort proteins from the Endoplasmic Reticulum and then distribute them to where they need to go.
- 6. Temporary storage bubbles for the cell, storing food, water, or waste.
- 7. Very simple, single-celled bacteria that do not have a membrane-bound nucleus, mitochondria, or organelles.
- 10. In some multicellular animals, the cell uses mitosis and cell division to produce a BUD of cells identical to the parent cell. When the bud is large enough, it can break off and live on its own with the resulting BUD is identical to its parent.
- 14. The cell’s transport organelle, processing and moving materials throughout the cell.
- 16. When one parent organism reproduces alone, resulting in new daughter organisms that are genetically identical to the parent.
- 17. The cell’s “control center”, housing the cell’s chromosomes.
- 19. The ability to regrow lost parts.
- 20. The time where a cell grows and duplicates its chromosomes and organelles in preparation for mitosis.
- 21. The parts of a cell. They process and release energy, destroy and digest materials, and replicate genetic information.
- 22. In plant cells only, they are organelles that produce food. Chlorophyll is a green pigment that makes plants look green and also uses energy from the sun to change water and carbon dioxide into glucose, a simple sugar.
Down
- 1. When 1 cell divides into 2 cells; 2 cells dividing into 4; 4 cells dividing into 8, and so on. So, an entire organism can grow from one cell alone.
- 3. Each cell goes through a life cycle; one complete cell cycle is the time from one cell division to the next. Different cells have different lengths of cycles.
- 5. The cell duplicates its genetic material, then the cell elongates causing the genetic material to split. The cell pinches down in the middle, producing two new daughter cells identical to the parent cell.
- 8. Protein-making factories in a cell.
- 9. A type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus
- 11. A protective double membrane surrounding the nucleus that controls the flow of materials in and out of the nucleus.
- 12. In mitosis a cell divides to form two identical daughter cells. It is important that the daughter cells have a copy of every chromosome, so the process involves copying the chromosomes first and then carefully separating the copies to give each new cell a full set. Before mitosis, the chromosomes are copied.
- 13. The cell’s powerhouse, releasing energy in food by carrying out a reaction with oxygen.
- 15. All organisms are made of cells (one or more);The cell is the basic building block of life (in structure and function);Every cell comes from another existing cell (cells divide to form new cells)
- 18. A cell that is the source of other cells.
