Picture of a root hair cell in the soil ^
The nucleus contains chromatin material, consisting of the DNA of the cell which is important inherited by the daughter cells. The cell wall is a strong surface, surrounding the plasma membrane, which protects the cell and give it its shape. It also prevents too much expansion when water enters the cell. The plasma membrane controls the movement of substance into and out of the cell and is used for cell identification. The vacuole helps in isolating materials that pose as a threat to the cell and also helps in exporting waste products from the cell. The cytoplasm consists of cytosol and the cellular organelles, except the nucleus. The cytosol is made up of water, salts and organic molecules and many enzymes that speed up reactions. It is important as it suspends the cell organelles within it.

I have learnt that there are 5 organelles found in a root hair cell. They are the: nucleus, cytoplasm, plasma membrane, cell wall and vacuole. T The root hair cells also enable water to be absorbed by the plant through a thin root-like structure protruding out of the cell.
ReplyDeleteI have learnt that the root hair cell has a large surface area but it is a delicate surface that can live up to 2-3 weeks. I have also learnt that root hair cells vary in their length and diameter.
ReplyDeleteEach of the organelles are important and special in helping the cell. The cytoplasm consist of cytosol,which is made up of water, salts, organic molecules and enzymes that speedup reactions.
ReplyDeleteI have learnt that there are 5 organelles, and each of them are unique, as each play a part in keeping the plant alive. And also that the cytosol suspends the organelles inside it.
ReplyDeleteI learnt that all the organelles in the root hair cell are important for the cell to survive.The cytoplasm contains cytosol in it and it has a large surface area for more water to enter the cell.
ReplyDeleteI learnt that everything in the cell has to work together and a root hair cell can live from 2-3 weeks

ReplyDeletecan you enlarge the root hair cell pictures.

ReplyDeletethank you soo much this has help so much my science teacher will be happy :)
ReplyDeletethanks so much i am totally going to be ahead in class now xxxx
ReplyDeleteThere are 5 organelles in root hair cells, so do you think "cytoplasm" and "nucleus"
ReplyDeletecan be classified as an organelle?
Definitely not.
organelles should be mitochondria,maybe Endoplasmic reticulum in root hair cells. correct me if im wrong i guess that mitochrondria provides the root hair cell energy by going through a process called aerobic respiraton, so as to to absorb nutrients mineral salts etc from the soil.Endoplasmic reticulum will then transport it to the xylem vessel to be transported to other parts of the cell.
ReplyDeleteThis info has really helped me for school! Thanks!
ReplyDeleteRoot cells contain the organelles mirchondria and nucleus. They also contain cell wall cell membrane vacuole and nucleus which aren't organelles :(
ReplyDeletewhat is the organelle helps the root to absorb the water?
ReplyDeleteThis info is so bad my rectum exploded
ReplyDeleteUseful but not very meaningful without a diagram.Try adding diagrams.
