are protection‚ giving structural support and helping in the filter mechanism. 2. Cell Membrane Cell membrane‚ also called plasma membrane‚ is present inside the cell wall and surrounds the cytoplasm. It connects the intracellular components (organelles and cytoplasm) with the extracellular environment‚ and helps in protection and transportation. The cell membrane is permeable to specific substances only. 3. Plasmodesmata Plasmodesma (plural plasmodesmata) is a small opening‚ which connects

Cellular Respiration Photosynthesis Organelles Mitochondria Chloroplast Organelle Structures The double-membraned mitochondrion can be loosely described as a large wrinkled bag packed inside of a smaller‚ unwrinkled bag. The two membranes create distinct compartments within the organelle‚ and are themselves very different in structure and in function. Two membranes contain and protect the inner parts of the chloroplast. The stroma is an area inside of the chloroplast where reactions occur and starches

Introduction Out of all the organelles there are two that have fascinated microbiologists for the past hundred years. The first is the mitochondria‚ nicknamed the "powerhouse of the cell." The second is the chloroplast in plant cells that have functions similar to those of the mitochondria. What do these organelles do? What are the similarities and differences of these organelles? This essay will help you to understand these two fascinating organelles. II. Mitochondria Mitochondria

to the nucleus‚ there are many organelles inside of the cell - small structures that help carry out the day-to-day operations of the cell. One important cellular organelle is the ribosome. Ribosomes participate in protein synthesis. The transcription phase of protein synthesis takes places in the cell nucleus. After this step is complete‚ the mRNA leaves the nucleus and travels to the cell’s ribosomes‚ where translation occurs. Another important cellular organelle is the mitochondrion. Mitochondria

Experiment IV: Study of Krebs cycle using Mitochondria from Mung Bean Seedlings INTRODUCTION The mitochondria is a very important organelle in the plant cell because it carries out very important cellular reactions in the cell like the Krebs cycle and oxidative phosphorylation which is how the plants produce ATP from the pyruvate produced through glycolysis (Meyer and Millar‚ 2008). Glycolysis produces a net of 2 ATP for the plant which is not enough for the cell to function while the Krebs cycle

basic units of structure and function in all living things. They carry out our life processes and make it possible for us to function and live. Inside these cells are organelles‚ which are smaller than the cell itself. However‚ without these organelles‚ the cell would not be able to function and we would die. Of these many organelles are the mitochondria‚
