Mar 19, 2017 · Cells are the basic unit of structure and function in human bodies. They contain specialized structures called organelles that perform specific functions. The cell membrane controls what enters and exits the cell. Movement across the membrane occurs through diffusion, osmosis, and active/passive transport. The nucleus houses DNA and controls ...

STRUCTURE: Largest cell organelle present in eukaryotic cells It is usually spherical It has double layer nuclear membrane with nuclear pores It has transparent granular matrix called nucleoplasm, chromatin network composed of DNA and histone proteins It also has a spherical body called Nucleolus FUNCTION: It is the control centre of the cell.
Apr 5, 2019 · Eukaryotic cells: Plant and animal cell • A side-by-side view of an animal and plant cell. Plant cells contain special organelles called chloroplasts and an outer covering called a cell wall. Animal cells lack both of these structures. Outside of cell Hydrophilic region TEM of a plasma membrane.
Acts as a form of digestive (lytic ) system or the cell, because enzymes present in it can digest essentially all macromolecules. Engulf worn out components of the cells in which they are located. Engulf exogenous substances e.g. bacteria and degrade them. When a cell dies ,lysosomal enzymes causes autolysis of the remanant .
