Why do plant cells appear green?

Answer 1

Green-appearing plant cells contain a lot of tiny green chloroplasts, the organelle for capturing light energy and doing photosynthesis. If you look under the microscope, you'll see they're not solid green, but our eyes lack the resolution to see those tiny organelles so the whole thing looks green.

Answer 2

In the cells of mesophyl tissue there are chloroplastids which contain chlorophyll-- a type of green pigment . According to Raman's effect the when the sunlight passes through a molecule of chlorophyll , only the wavelength of green colour is scattered( a kind of reflection).

So, for the molecular structure of chlorophyll the only plantcells which contain chlorophyll appear green.

Answer 3

What Organelle Makes Plants Green

Answer 4

Chloraphyl reflects back the color green in the normal light spectrum. Shine a red light on your plants and they will look brown.

Division Plane Determination in Plant Cells

During plant development, cell walls ensure that the relative positions of cells change little, if any. Consequently, the cellular organization of a mature plant tissue closely reflects the pattern of cell division during its development. In some species and tissue types, a virtually invariant sequence of oriented divisions elaborates a characteristic cell pattern. For example, stereotypical division patterns in the root tips of Azolla (a fern) and Arabidopsis (a dicot) establish the very regular arrangement of cells in these tissues (Gunning et al., 1978; Dolan et al., 1994). In other tissues, such as the maize leaf, division pattern is more variable but nevertheless follows certain general rules that preserve a characteristic cellular organization (Langdale et al., 1989; Sylvester et al., 1990). Therefore, it is perhaps not surprising that plant cells appear to carefully control their division planes.

How does a plant cell preparing to divide choose an appropriate division plane? It was first recognized over 100 years ago that the division planes of most plant cells could be predicted simply from their shapes. In 1863, Hofmeister noted that new cell walls are usually formed in a plane perpendicular to the main axis of cell expansion—that is, perpendicular to the long axis of the mother cell. In 1888, Errera formulated the rule that the plane of division for most cells corresponds to the shortest path that will halve the volume of the mother cell, corresponding to a plane perpendicular to, and bisecting, the long axis of the mother cell. The notion that the plane of division can be dictated simply by cell geometry is further supported by experimental evidence. Spherical cultured cells suspended in semi-solid medium divide in random orientations. However, if these cells are squeezed into slightly oval shapes through application of a compressive force, the majority divide in a plane perpendicular to the oval's long axis (Lynch and Lintilhac, 1997). Although it is not fully known how a plant cell could read its shape and divide accordingly, Lloyd and colleagues proposed a model based on simple mechanical principles that could largely explain cells' ability to follow Hofmeister's and Errera's rules (Lloyd, 1991).

While simple geometrical rules predict the division planes of most cells, many do not follow these rules, and may be responding to local cues of some kind that override the influence of cell shape on the division plane. The asymmetric divisions involved in the formation of many specialized cell types such as stomatal complexes provide a good example. In grasses, stomata form through an invariant sequence of asymmetric divisions illustrated in Figure 1 (Stebbins and Shah, 1960). The first asymmetric division leads to the formation of a small guard mother cell, which will divide later to form a pair of guard cells. Before it divides again, asymmetric division of the guard mother cell's lateral neighbors (subsidiary mother cells) results in the formation of subsidiary cells, which will flank the guard cells. Prior to each of these asymmetric divisions, the mother cell becomes polarized, involving migration of the nucleus to one side of the cell as well as redistribution of the cytoplasm and other cell components. In these cells, the division plane is related to the cell's polarity rather than its overall shape. Polarization of subsidiary mother cells in particular is thought to be controlled by a signal of some kind from the guard mother cell. Other cells that divide in a manner not predicted by their shapes may similarly be responding to extracellular cues, but this remains to be determined.

Answer 6

chlorophyll present in the chloroplast which produce food for the plant. its chemical formula is C6H12O6.

Answer 7

its b'coz of chlorophyll which absorbs all colours except green.

hey 'palm_of_buddha'.. the composition for chlorphyll is NOT C6H12O6. that's for glucose.

chlorophyll has a rather complicated structure

Answer 8

Tthey absorb all of the other colors of the spectrum and reflect green.

Answer 9

Chlorofil? More like bore-ofil.

Answer 10

Because of chloroplast.
