STRUCTURE OF A CELL 1. Plasma Membrane and Cell Wall 2. Cytoplasm and Organelles The cytoplasm serves as the general storage and working area of the cell. It contains the following structural bodies: a. Endoplasmic reticulum a.1 Rough endoplasmic reticulum a.2 Smooth endoplasmic reticulum b. Mitochondria c. Golgi apparatus d. Lysosomes e. Centrioles f. Plastids f.1 chloroplasts – contain green pigments chlorophyll! which traps light for photosynthesis. f.2 chromoplasts " contain red# yellow# and orange pigments characteristics of carrots# flowers# tomatoes# etc. f.$ leucoplasts " contain pigments for colorless appearance# e.g. starch grains in rice# potatoes# radish. g. Vacuoles h. Microfilaments and microtubules $. Nucleus The nucleus has the following parts: a. Nuclear Membrane b. Nucleoplasm b.1 nucleolus b.2 chromosomes
