Which of the following does a prokaryotic cell have that an animal cell does not? a. Ribosomes. b. Cell wall. c. Vacuole. d. DNA. Cell Organelles: A cell is a structure that is found in both plants and animals. A cell can b...
How are proteins packaged and transported within a cell? How do cilia and flagella bend? How are cells affected by the movement of water? How do cells store energy? How is a cell like a factory? What is the difference between an animal and a plant's cell?
Tip-localized Ca2+gradients play a part inside the cell during cell expansion. The maintenance of turgor during growth relies on signal transduction pathways, and particularly on an osmotic mitogen-activated protein kinase cascade that regulates the accumulation of solutes (including ion uptake from the...
Protozoa play animportant role in mineralizing nutrients, making them available for use by plants and other soil organisms. Protozoa (and nematodes) have a lower concentration of nitrogen in their cells than the bacteria they eat. ... Another role that protozoa play is in regulating bacteria popu...
Eukaryotic cells have aninternal cytoskeletal scaffolding, giving them their distinctive shapes. The cytoskeleton enables cells to transport vesicles, undergo changes in shape, migrate and contract. Do bacteria have Axoneme? Bacterial flagella are helical filaments, each with a rotary motor at its base...
This method may also be problematic in the case of varying sperm morphologies such as those found in numerous animal species. Sperm also have long, flexible flagella, thus shape is not constant. Excluding the measurement of these flagella results in the loss of information about sperm movement. ...
A role in vesicle trafficking would place LRRK2 in an ideal pos- ition to regulate cell-to-cell transmission of pathogenic α-synuclein. Further, recent studies have suggested that not only is mutated LRRK2 overactive, LRRK2 in idio- pathic PD patients may also be overactive [8, 12]....
