section 7.2 eukaryotic cell structure
in your textbook, read about cellular boundaries; nucleus and cell control; assembly, transport, and storage in the cell; and energy transformers.
complete the table by writing the name of the cell part beside its structure/function. a cell part may be used more than once.

1. a membrane - bound, fluid - filled sac
2. closely stacked, flattened membrane sacs
3. the sites of protein synthesis
4. a folded membrane that forms a network of interconnected compartments in the cytoplasm
5. the clear fluid inside the cell
6. organelle that manages cell functions in eukaryotic cell
7. contains chlorophyll, a green pigment that traps energy from sunlight and gives plants their green color
8. digest excess or worn - out cell parts, food particles, and invading viruses or bacteria
9. small bumps located on the endoplasmic reticulum
10. provides temporary storage of food, enzymes, and waste products
11. firm, protective structure that gives the cell its shape in plants, fungi, most bacteria, and some protists
12. produce a usable form of energy for the cell
13. modifies proteins chemically, then repackages them
14. contains inner membranes arranged in stacks of membranous sacs called grana
15. plant organelles that store starches or lipids or that contain pigments

Explanation:

1. Vacuoles are membrane - bound, fluid - filled sacs.
2. Golgi apparatus consists of closely stacked, flattened membrane sacs.
3. Ribosomes are the sites of protein synthesis.
4. Endoplasmic reticulum is a folded membrane that forms a network of interconnected compartments in the cytoplasm.
5. Cytoplasm is the clear fluid inside the cell.
6. Nucleus is the organelle that manages cell functions in eukaryotic cell.
7. Chloroplast contains chlorophyll, a green pigment that traps energy from sunlight and gives plants their green color.
8. Lysosomes digest excess or worn - out cell parts, food particles, and invading viruses or bacteria.
9. Ribosomes are small bumps located on the endoplasmic reticulum.
10. Vacuoles provide temporary storage of food, enzymes, and waste products.
11. Cell wall is a firm, protective structure that gives the cell its shape in plants, fungi, most bacteria, and some protists.
12. Mitochondria produce a usable form of energy for the cell.
13. Golgi apparatus modifies proteins chemically, then repackages them.
14. Chloroplast contains inner membranes arranged in stacks of membranous sacs called grana.
15. Plastids are plant organelles that store starches or lipids or that contain pigments.
