Correct option is B) Was this answer helpful? Smooth endoplasmic reticulum is responsible to produce lipids and other steroids. As chloroplasts and mitochondria do not derive de novo they need to divide by fission to be maintained and increase populations in leaf development. Solution. Mitochondria are absent in: A. fungi. The central vacuole is a cellular organelle found in plant cells. Centrioles are the part of centrosome located near the nucleus in the animal cell and some lower plant cells. Similar questions. The mitochondria are virtually present in all the aerobic cells. Without ATP, the cell no longer has the energy needed to function. Plant cells use a different method to activate cytokinesis: they use the cell's nucleus. Bacteria are prokaryotes and they do not have mitochondria. In addition to having mitochondria to produce ATP, plant cells also contain . Cytokinesis is the process of separating cells to create new ones. But in higher plants, it is absent. Theoretically mitochondria are believed to have been created as prokaryotic cells. All animal cells have centrioles whereas only some lower plant forms have centrioles in their cells (e.g. 0.

Commonalities of energy processing in both plants and animals have become even stronger by the finding that chloroplast can be found . Just as the chloroplasts in plants act as sugar factories for the supply of ordered molecules to the plant, the mitochondria in animals and plants act to produce the ordered ATP molecules as the energy supply for the processes of life. Plant cells typically contain several hundred physically discrete mitochondria. They produce ATP through the breakdown of glucose, ATP (Adenosine Triphospate) which is called as the energy produced by the oxidation of glucose. But in higher plants, it is absent. D. plant cells.
