Meristematic cells are mainly concerned with cell division . Their primary function is mitosis . They do not have any waste materials to store so vacuole is usually absent in meristematic cells . Why do meristematic tissues lack vacuoles and have prominent nucleus? Meristematic cells have a prominent nucleus, denseRead More →

The vacuole is also a type of vesicles. Plant cells contain a large, central vacuole, storing mostly water and nutrients. The main difference between vesicles and vacuole is that vesicle is designed to store different types of molecules whereas vacuole is a type of vesicle, mostly storing water. What areRead More →

Lysosomes are an important type of vesicles involved in the digestion. Food vacuoles are fused with lysosomes, which contain enzymes to digest the food. Lysosomes are also involved in phagocytosis. On the other hand, lysosomes destroy damaged organelles in the process called autophagy. How are lysosomes and vacuoles the sameRead More →

Collenchyma tissue is composed by elongated living cells of uneven primary thick walls, which possess hemicellulose, cellulose, and pectic materials. … Collenchyma cells may or may not contain a few chloroplasts, and may perform photosynthesis and store food. What is the characteristic of collenchyma? The three most characteristic morphological featuresRead More →

Autophagic vacuoles (AVs) arise when membranes of the ER sequester parts of the cytoplasm, forming a new, double-membraned vacuole, to which lysosomal enzymes are then delivered. … Consistent with these results, treatment of cells with tunicamycin had no effect on autophagy-induced proteolysis. How are autophagic vacuoles formed in cells? AutophagicRead More →

Explanation: vacuole is a cell organelle which contains mainly water while lysosomes also cell organelle and are regarded as suicide bags by function. Vacuoles stores the undigested nutrients while the Lysosomes are the membrane bound sacs containing digestive enzymes that breaks down large molecules. When lysosomes fuses with a phagosomeRead More →

Meristematic cells divide frequently and give rise to new cells and hence they need dense cytoplasm and thin cell wall. Vacuoles causes hindrance in cell division as it is full of cell sap to provide turgidity and rigidity to the cell. … Meristematic cells do not need to store theseRead More →

Meristematic cells have a prominent nucleus, dense cytoplasm and lack vacuoles and are because: these cells do not store food material or waste materials. Hence they lack vacuole. As vacuoles possess cell sap and provide rigidity and turgidity to the cell. Why do meristematic cells lack vacuoles and have prominentRead More →
