Why are the organelles important?

Answer 1

There are many organelles within cells. Endosymbiotically originated organelles are of great importance. They include chloroplasts which derive sugar molecules in plants photoautotrophically by photosynthesis. And mitochondria, also arisen endosymbiotically catabolyse the sugars into energy in the plant, or energy in the animal that may have ingested sugars. Chloroplasts contain photosystems, from which electrons are energised by sunlight. The moving electrons are used to reshuffle carbon dioxide and water into sugars. Lysosomes, in acidic conditions are important as they destroy pathogens that may be embedded in endocytotic vacuoles. Ribosomes are the sites of protein synthesis, the stringing together of aminoacids to form proteins as per the instructions in the DNA of a cell's nucleus. Ribosomes attach to membranous and saclike 'pathways' within the cell for protein synthesis. These 'paths' are called the granular endoplasmic reticulum. The nucleus holds the DNA in chromatin, or, at cell division, in chromosomes. The nucleolus of the nucleus holds the NOR for synthesising ribosomes and the DNA codes for rRNA.

Answer 2

Organelles are important to a cell because they are like organs in a human. Without organelles a cell would not be able to do anything, would not be able to do its job, and would be dead.

Answer 3

they have to do with respiration is one reason i know they're so important.
