It has tiny pores called Plasmodesmata that connect neighboring cells. B. Cell Membrane (কোষঝিল্লি)

| Organelle | Function | Found In | | :--- | :--- | :--- | | | Controls all activities of the cell; contains DNA. | Plant & Animal | | Cytoplasm | Jelly-like substance where chemical reactions occur. | Plant & Animal | | Cell Membrane | Controls the movement of substances in and out of the cell. | Plant & Animal | | Mitochondria | The "powerhouse" of the cell; produces energy (ATP). | Plant & Animal | | Ribosomes | Synthesizes proteins. | Plant & Animal | | Cell Wall | Provides structural support and protection for the cell. | Only in Plants | | Chloroplasts | Site of photosynthesis; contains chlorophyll. | Only in Plants | | Large Vacuole | Stores water, nutrients, and waste products. | Only in Plants | To help customize this study guide further, what

Network of membranes for transport. Rough ER: Has ribosomes. Smooth ER: No ribosomes, synthesizes lipids.

The foundation of this chapter lies in understanding the structural differences between plant and animal cells. | Plant & Animal | | Cytoplasm |

Covers body surfaces and lines internal cavities. Cells are tightly packed on a basement membrane.

The "Powerhouse." Site of oxidative phosphorylation and ATP production. Chloroplast: Green, conducts photosynthesis. Chromoplast: Coloured (red/yellow), attracts pollinators. Leucoplast: Colourless, stores food. Ribosomes: Protein factories of the cell. Golgi Body: Packaging and secretion center. Lysosomes: Contains digestive enzymes; acts as the "suicide bag." 3. Plant Tissues Simple Tissue: Made of one type of cell. Parenchyma: Thin-walled, living, stores food. Collenchyma: Thickened at corners (pectin), provides flexibility. Sclerenchyma:
