Nucleus Nuclear envelope: membrane enclosing the nucleus. Protein-lined pores allow material to move in and out. Chromatin: DNA plus associated proteins. Nucleolus: condensed region where ribosomes Cytoskeleton Microtubules: form the mitotic spindle and maintain cell shape. Centrosome: microtubule- organizing center. Intermediate filaments: fibrous proteins that hold organelles in place. Microfilaments: fibrous proteins; are formed. form the cellular Peroxisome: Plasma metabolizes membrane waste digests food and waste materials. Golgi apparatus: modifies proteins. Endoplasmic reticulum Rough: associated with ribosomes; makes secretory and membrane proteins. Smooth: makes lipids. Cytoplasm Mitochondria: produce energy. Nucleus contains chromatin, a nuclear envelope, and a nucleolus, as in an animal cell Plasmodesmata channels connect two plant cells Endoplasmic Reticulum smooth rough Cell wall maintains cell shape Plasma membrane Cytoplasm Central Vacuole filled with cell sap that maintains pressure against cell wall Golgi apparatus Mitochondria Cytoskeleton microtubules intermediate filaments. microfilaments microfilaments Peroxisome Plastid store pigments Chloroplast site of photosynthesis (b) NUCLEUS Ni Chromatin.
