Final answer:
Based on genome sequences, the presence or absence of cytoplasmic dynein in different plants is not surprising. Additional research can be conducted to confirm or refute this finding, such as comparing genome sequences and conducting experimental studies. Higher plant cells can operate without cytoplasmic dynein due to the presence of alternative mechanisms for intracellular motility.
Step-by-step explanation:
Based on the provided information, it is not surprising that cytoplasmic dynein is absent in some plants and present in others. Cytoplasmic dynein is a motor protein responsible for intracellular motility, including the movement of organelles along microtubule tracks. Different plants have different cellular structures and requirements, which may explain the presence or absence of cytoplasmic dynein.
To confirm or refute the statement about the presence or absence of cytoplasmic dynein in different plants, additional research can be conducted. This research may involve comparing the genome sequences of different plant species to detect the presence of the cytoplasmic dynein gene. Furthermore, experimental studies can be conducted to observe the movement of organelles within plant cells to determine if cytoplasmic dynein is present and functional.
Higher plant cells can operate without cytoplasmic dynein because they have alternative mechanisms for intracellular motility. For example, plant cells have other motor proteins such as kinesin that can transport cargo along microtubules. Additionally, plant cells have actin filaments that contribute to intracellular movement. These alternative mechanisms allow higher plant cells to function and perform necessary cellular processes without cytoplasmic dynein.
