Parts of Cells

peroxisome

carries out diverse metabolic processes, produces hydrogen peroxide that it converst into water

nucleolus

produces rRNA and proteins

nucleus

contains most of the genes that control the cell

rough endoplasmic reticulum

secretory proteins and membranes are manufactured here

smooth endoplasmic reticulum

lipid synthesis, detoxification, calcium storage

golgi apparatus

modifies, stores, and repackages products of endoplasmic reticulum usually for secretion

ribosomes

serve as the site of protein synthesis

microtubules

rods that shape and support the cell, serve as tracks along which other organelles can move

centrioles

makes centrosomes that prepare for cell division

mitochondria

carries out cellular respiration MAKES ATP

microfilaments

thin, solid protein rods involved in cell support and movementpl

plasma membrane

selective barrier, allows passage of oxygen, nutrients, and waste

lysosome

digestive enzymes that break down nutrients, destroy bacteria, recycle, and develop

cytoplasm

holds organelles in place, protects them from damage

intermediate filaments

support cell shape and fix organelles in place

cell wall

rigid structural support

central vacuole

maintains turgor pressure, stores water and nutrients and waste products

chloroplast

site of photosynthesis
