These data were subjected to linear regression analyses to identify the parameters that determine differences in organ growth., Our results demonstrate that, across all species and organs, similar conclusions can be made: cell number rather than cell size determines the final size of plant organs; ...
Simply a seedling but how did it become one and what are the details as it transforms into a large plant? Plant developmentis an overall term that refers to the various changes that occur in a plant during its life cycle. In consideration of various horticultural crops and products, Watada ...
These plant organs include bulbs and bulblets, cloves, corms and cormels, tubers and tubercles, tuberous roots, rhizomes, runners, stolons, slips, suckers, crowns, and plantlets. These plant organs can be used deliberately as they are, without significant changes, in plant propagation as pla...

: the embryo. The embryo in plants, whether it's found in a seed or a bud, contains the early form of the organs the plant needs to live. When conditions are right, the embryo bursts out of its container and becomes a seedling – beginning the process of growing into an adult plant...
Microscopic pores found in the epidermis of leaves, stems and other plant organs that facilitate gas exchange. Pores are bordered by specialized epidermal cells known as guard cells that are responsible for regulating the size of the stomatal opening. Pathogen-associated molecular patterns (PAMPs). ...
How are enzymes produced in a cell? (a) What are enzymes? (b) What are they for? What general role do enzymes play in life? Explain. What are the cofactors of enzymes? What plant enzymes have functions similar to human enzymes?
It involves the preparation and analysis of plant and animal tissues. A microscope is used to view the structure of the tissues.What is Tissue? A cell is the basic unit of life. Various specialized cells in a multicellular organism can be grouped to perform the same function, thus forming ...
Other forms of life, however, are made of only a single cell, such as the many species of bacteria and protozoa. Cells, whether living on their own or as part of a multicellular organism, are usually too small to be seen without a light microscope. Cells share many common features, ...
