Why does a cell undergo mitosis? Why are there no chloroplasts in onion cells? Why do erythrocytes always use anaerobic instead of aerobic glycolysis? Why is mitochondria impermeable to oxaloacetate? Why are prokaryotic cells generally smaller than eukaryotic cells?
During mitosis, the spindle also forms in the absence of conspicuous MTOCs. Both poles of the spindle are broad, and branched structures of microtubules called microtubule converging centers form at the poles. In this review, we hypothesize that the microtubule converging centers form via ...
How is mitosis different in plants and animals? What is the difference between pollination and fertilization? How do members of Filicinophyta reproduce? The seeds of cycads develop within a What will a fertilized egg develop into in seedless plants?
Are spores in ferns produced by mitosis or meiosis? Spores, rather than gametes, are the unicellular, haploid products ofmeiosisin fern plants. Spores in turn undergo mitotic cell divisions to produce the multicellular, haploid gametophyte. Relative to the familiar sporophytes, the fern gametophytes...
A tumour caused byAgrobacteriumand often found on the crown (the root–stem junction) of plants. Cytokinin A group of adenine-related plant hormones that regulate cell division and differentiation. Endocycle A cycle of DNA replication without mitosis or cell division, resulting in increased nuclear...
Do somatic cells make gametes? Sperm and egg: Gametes or gametic cells are sperm cells in men and egg cells, or ovum, in women. The sperm is the smallest cell in the human body. The ovum is the largest cell found in the human body. ...

Cytokinesis occurs inmitosis and meiosisfor both plant and animal cells. The ultimate objective is to divide the parent cell into daughter cells. In plants , this occurs when a cell wall forms in between the daughter cells. In animals , this occurs when a cleavage furrow forms. ...
- The process of mitosis ensures that the new plants produced are genetically identical to the parent plant. This means that the offspring will have the same genetic makeup as the parent. 5. Clones: - Since the offspring produced through vegetative reproduction are genetically identical to the...
