Nothing more and nothing less, YES
It Was Robert brown,a scottish botanist.
dark reddish and brownish or purple colored
Plant cell nucleus are a very essential part of the entire cell structure. They are specialized for purposes of administration and processing information for the cell.
Yes. The only difference between a plant cell and an animal cell is that a plant cell has a cell wall.
Parenchyma, companion, sieve tube, & xylem cells have no nucleus. But, those are only the cells with out a nucleus that are fuctional.
The nucleus is pink and the cell wall is orange and the cytoplasm is brown and vacleous is yellow with blue dots inside of it. the cell membrane is grey the cloroplast isblack…
The Nucleolus is either dark red or brown and the nucleus is always Black in color
Yes. They are eukaryotic cells, and all eukaryotic cells have nuclei.
Cell nucleus discovery The question is debatable as Thonius Philips van Leeuwenhoek (October 24, 1632 - August 30, 1723)1, Dutch scientist first observed t…he cell nuleus. "In 1682 he clearly described the nucleus within the red blood cells of fish, and in 1683 he noticed the sedimentation of erythrocytes from a suspension and their lysis upon addition of water."2 It was Robert Brown (December 21, 1773-June 10, 1858)3 a Scottish Botanist who observed and gave the name "cell nucleus". Brown, is best known for the discovery of Brownian motion random movement within fluids due to molecular energy of fluid and also used as a mathematical model for Stochastic processes (random i.e. financial markets, atmospheric events).2,4 Some sources site Brown and not van Leeuwenhoek as the discoverer.5 http://en.wikipedia.org/wiki/Anton_van_Leeuwenhoek1 http://www.bookrags.com/Anton_van_Leeuwenhoek2 http://en.wikipedia.org/wiki/Robert_Brown_(botanist)3 http://www.brianjford.com/wbbrowna.htm4 http://science.discovery.com/convergence/100discoveries/big100/biology.html5
Mostly but not always, specialist cells like the Xylem cells do not have nuculi because they are made up of recycled cell matter. yes
cell discovery: cell was discovered by Robert hooke in 1665.As he was observing a piece of cork under the microscope he noticed small chambers like honey comb in them.those c…hambers were called cells by ROBERT BROWN.Later another scientist ROBERT BROWN discovered the nucleus in the cell of orchid. A German scientist SHWANN discovered the animal cell with nucleus.
Every plant cell has a nucleus because a nucleus controls the cell's main activities.
the nucleus contains the bodies genetic material - in the form of DNA, stored in chromosomes. The nucleus has a double membrane called the nuclear envelope The nuclear lamina …is also found within the nucleus, which is kind of a mesh network which adds support to the nucleus. I think its made up of structural proteins. Then you find the Nucleolus.
In general yes, although there are exceptions such as the xylem cells
The nucleus is the region of the cell that contains the genetic material of the cell which are pairs of chromosomes. The chromosomes are responsible for controlling the metabo…lic and reproductive activities of the cell. In plants pairs of chromosomes (diploid or 2n) are found in most general cells; specialised cells such as pollen grains and the ovules contain haploid (or n) single chromosomes which are formed through the process of meitosis. When the egg is fertilised (through cross pollination) one the single chromosomes join to become diploid again (2n), thus the new plant inherits genetic material from each parent. In pollen is it actually more complicated than that as there are normally 3 sets of chromatids, but two of these control the growth of the pollen tube and eventually degenerate leaving a single set to fuse with the set from the ovule.
The plant cell has a cell wall outside the cell membrane which gives it a regular shape, unlike animal cells. Inside the plant cell, there is a large fluid filled sac called t…he vacuole which also helps to maintain the cell's shape and which takes up most of the space that in an animal cell is filled up by cytoplasm. In the little space remaining between the vacuole and the cell membrane, there is the cytoplasm, where the nucleus is found. So the nucleus in a plant cell is found at the edge in the cytoplasm close to the cell membrane!!
