- It has a cell membrane with pores; that regulate substances entering and leaving the cell.
- It has cytoplasm that contains sugars and salts; for maintaining its osmotic pressure;
- also has a liquid
medium; for all biochemical reactions. - It has a nucleus that contains chromosomes having hereditary
material and controls all the activities of the cell. - It has ribosomes which are sites for protein synthesis.
- It has Golgi bodies or Golgi apparatus; for secretion of hormones and enzymes and formation of lysosomes.
- It has lysosomes which contain lytic enzymes for breaking down worn-out organelles;
- It has secretory vesicles;
formed from the Golgi apparatus for secreting substances. - It has smooth endoplasmic reticulum for synthesizing and transporting lipids.
- It has rough endoplasmic reticulum; transports proteins;
nucleolus; controls the activities of the nucleus; produces ribosomes; - It has mitochondria which form
sites for energy production. - It has centrioles that are responsible for the formation of cilia and flagella and forms spindle fibres
used in cell division; - It has plant sap vacuoles that stores salts and other dissolved substances and control
osmotic pressure and turgidity of cells. - It has food vacuoles involved in the digestion of engulfed food;
chloroplasts; form sites for photosynthesis in plant cells.
