In both organelles, the innermost membranes – cristae, or infoldings of the inner membrane,… Both organelles are involved in energy transformation, mitochondria in cellular respiration & chloroplasts in photosynthesis.
Why do plants need both chloroplasts and mitochondria?
Plant cells need both chloroplasts and mitochondria because they perform both photosynthesis and cell respiration. Chloroplast converts light (solar) energy into chemical energy during photosynthesis, while mitochondria, the powerhouse of the cell produces ATP- the energy currency of the cell during respiration.
What is the function and structure of mitochondria?
A mitochondrion is a round to oval-shaped organelle found in the cells of almost all eukaryotic organisms. It produces energy, known as ATP, for the cell through a series of chemical reactions.
What is the function of mitochondria in Class 11?
Mitochondria are the sites of aerobic respiration and produce cellular energy in the form of ATP, hence they are called ‘power houses’ of the cell. The matrix also possesses single circular DNA molecule, a few RNA molecules, ribosomes, and a few components of protein synthesis.What is the function of mitochondria for Class 7?
Mitochondria are a part of eukaryotic cells. The main job of mitochondria is to perform cellular respiration. This means it takes in nutrients from the cell, breaks it down, and turns it into energy. This energy is then in turn used by the cell to carry out various functions.
What is the function of mitochondria Class 6?
What are the functions of Mitochondria? Mitochondria’s primary function is to produce energy through the process of oxidative phosphorylation.
