Cell Structure and Function

Cell is the basic structural and functional unit of life, All living organisms are composed of cells, All cells arise from pre-existing cells

The cell theory states three main points: cells are basic units of life, all living organisms are made of cells, and all cells come from pre-existing cells. Both unicellular and multicellular organisms have cells.

Cell membrane, Cytoplasm, DNA

All cells have three major components: plasma membrane, cytoplasm, and DNA. Cell wall is only in plant cells and bacteria, while nucleus is only in eukaryotic cells.

Cell wall, Chloroplasts, Large vacuoles

Plant cells have rigid cell walls, chloroplasts for photosynthesis, and large vacuoles. Mitochondria and ribosomes are found in both plant and animal cells.

Phagocytosis

Phagocytosis is the process of taking in solid particles by endocytosis. Pinocytosis is for fluid droplets, while diffusion and osmosis are passive transport processes.
