The centriole: Animal cells have one; plant cells don't. They are regarded as the power houses of the cell with variable size and shape. In plant cell, cytoplasmic streaming can be used to distribute chloroplasts for maximum light absorption for photosynthesis. While mouse oocytes do have centrioles, they play no role in nucleus positioning, yet. Even a big fat cell has most of its cytoplasm very close to the cell membrane (the center is occupied by a huge oil droplet). DNA supercoil Cell nucleus . The cell consists of well-defined subcellular organelles, enveloped by a plasma membrane. What does the mitochondria do in a plant cell? Plant Cell Mitochondria Cytoplasmic streaming also allows the long-distance transportation of biological molecules across different cells. It was initially called dormant. Does cytoplasmic streaming happen in human cells? The key is to look at the right specimens. Cell Wall Lignin is the major component of wood. Piles of thylakoids are located in the central region called stroma. Cytoplasmic streaming can bring molecules to flow through these small pores and move upward along the phloem. Scientists had found these conditions: Chemicals that interact with cytoskeletons may also affect cytoplasmic streaming. Mitochondrion The cell wall: Plant cells have an outer cell wall; animal cells simply have the plasma membrane. 62.2. The nucleus of the oocyte still maintains a central position due to cytoplasmic streaming. Animal Cells vs. Plant Cells. Each step uses one molecule of energy.
