The label A represents mitochondria.
The mitochondria is also called the powerhouse of the cell which converts glucose to energy rich molecules of ATP.
Label B represents nucleus.
Nucleus contains the genetic material or DNA, RNA , nucleolus, chromatin fibres and proteins. It contains the chromosomes which control the hereditary characteristics.
Label C represents lysosome.
Lysosomes contain digestive juices which breaks down large cell parts and large molecules and helps in intracellular digestion.
Label D represents rough endoplasmic reticulum having ribosomes.
The rough endoplasmic reticulum provides surface for protein synthesis. It is also used to transport cellular contents from one cell to another.
The animal cell is defined as the eukaryotic cell with the plasma membrane, cytoplasm, nucleus, and membrane-bound organelles. The cell is the functional and structural unit of life.
The labeled parts in the image are:
Mitochondria is the powerhouse of the cell. It yields high-energy molecules, ATP to maintain the requirements of the cell. The Kreb's cycle occurs in the mitochondrial matrix and they have their own genetic material.
The nucleus is the distinctive feature of the eukaryotic cell. It is present in the center of the cell. It encloses the genetic material within it and carryout certain vital functions during cell division.
The lysosome is the cell organelle, which stores the digestive juices. The large cell debris and molecules are engulfed by lysosomes, which help in intracellular digestion.
The rough endoplasmic reticulum is involved in the synthesis and transport of proteins. The ribosomes are present on the endoplasmic reticulum, which gives it a rough appearance.
