A typical plant cell, has a distinct cell wall as its outer boundary and just within it is the cell membrane . Cells that have membrane bound nuclei are called eukaryotic whereas cells that lack a membrane bound nucleus are prokaryotic . in both prokaryotic and eukaryotic cells, a semi- fluid matrix called cytoplasm occupies the volume of the cell. The cytoplasm is the main arena of cellular activities in both the plant and animal cells. various chemical reactions occurs in it to keep the cell in the living state., Besides the nucleus, the eukaryotic cells have other membrane bound distinct structures called organelles like the endoplasmic reticulum (ER), the golgi complex, lysosomes, microbodies . the prokaryotic cells lack such membrane bound organelles. Ribosomes are non-membrane bound organelles found in all cells - both eukaryotic as well as prokaryotic cells. Within the cell, ribosomes are found not only in the cytoplasm but also within the two organelles chloroplast (in plan
