1. the __________________ is known as the brain or control center of the cell and has genes.
2. it is an intracellular transport system and is made of a series of channels (from the nucleus to cell membrane) throughout the cytoplasm of the cell. __________________________
3. structures normally found in animal cells, not in plant cells and are involved in animal cell reproduction. __________________________
4. involved in making ribosomes in the cell, this structure is located in the nucleus. ________________
5. the structure is the outer covering of a cell and is involved in regulating the movement of materials (food, gases, elements) in and out of the cell. __________________________
6. cellular respiration occurs in this organelle because this produces energy (atp) for cell activities. sometimes it is called the \powerhouse of the cell\, the organelle is the __________________________
7. the double membrane surrounding the nucleus that controls what enters and leaves it, is called the: __________________________
8. structures that contain digestive enzymes are __________________________
9. outside the cell membrane of a plant cell is the __________________________ that also serves as support and protection for the cell.
10. enzymes are proteins, and proteins are produce in this organelle __________________________
11. sacs storing water, wastes and food are storage chambers in the cell. __________________________
12. structure found in plants, but not animal cells, that carries out photosynthesis is the __________________________
13. dna material located in the nucleus of the cell is known as __________________________ and during mitosis it changes and can be seen as chromosomes.
14. the __________________ is area outside the nuclear membrane but inside the cell membrane, and cell parts are located.
15. the structure of the cell that prepares and packages proteins for use within the cell or shipment outside the cell. __________________________

Explanation:

1. The nucleus contains genetic material (genes) and controls cell - activities, acting as the control center.
2. The endoplasmic reticulum is an intracellular transport system with channels throughout the cytoplasm.
3. Centrioles are found in animal cells and are involved in cell - reproduction, not present in plant cells.
4. The nucleolus is located in the nucleus and is involved in ribosome synthesis.
5. The cell membrane is the outer covering that regulates the movement of substances in and out of the cell.
6. Mitochondria are the sites of cellular respiration and produce ATP, hence called the "powerhouse of the cell".
7. The nuclear membrane is a double - membrane surrounding the nucleus that controls what enters and leaves it.
8. Lysosomes contain digestive enzymes.
9. The cell wall is outside the cell membrane in plant cells and provides support and protection.
10. Ribosomes are the sites of protein synthesis.
11. Vacuoles are storage chambers for water, wastes, and food in the cell.
12. Chloroplasts are present in plant cells and carry out photosynthesis, not found in animal cells.
13. Chromatin is the DNA material in the nucleus that condenses into chromosomes during mitosis.
14. The cytoplasm is the area between the nuclear membrane and the cell membrane where cell parts are located.
15. The Golgi complex prepares and packages proteins for use within or outside the cell.
