Plant cells are eukaryotic cells that do not vary in size and they are similar to the rectangular or cubic shape. It consists of a cell wall, central vacuole, and plastids. Answer and Explanation:1 The Rigid shape of the plant cell is due to the presence of cellulose which is a homopoly...
What are the membranes that envelop the vacuole of a plant cell? The central vacuole in plant cells (see Figure 1) is enclosed by a membrane termedthe tonoplast, an important and highly integrated component of the plant internal membrane network (endomembrane) system. Which one of the following...
Which structure is usually present only in animal cells? (a) Vacuole (b) Cell wall (c) Nucleus (d) Centriole. Which cell organelle is called the headquarters of a cell? Which of the following structures is present in both prok...

The formation of plant autophagosomes and their delivery to the vacuole do not depend on ATG8 delipidation To verify that the EosFP-positive puncta observed in the vacuoles of atg4a/b plants were indeed autophagic bodies labeled with the EosFP–ATG8–PE adduct, we expressed EosFP–ATG8E Δ...
Most plant cells contain a large central vacuole that is essential to maintain cellular turgor. We report a new mutant allele of VTI11 that implicates the SNARE protein VTI11 in homotypic fusion of protein storage and lytic vacuoles. Fusion of the multiple vacuoles present in vti11 mutants ...
In this study, we demonstrate that WAT1 is a so far unknown tonoplast-localized auxin transporter, suggesting a critical role for the vacuole in regulating intracellular auxin homoeostasis in plants. Further, the fact that the reduction in secondary cell wall thickenings in wat1 mutants can be ...
Chloroplasts are plant cell structures that are essential for the photosynthetic process of the plants. Photosynthesis is the method that allows the plant to manufacture their food, and without chloroplast, there would be no photosynthesis to occur in the plants. Lastly, the central vacuole works ...
