A plant cell needs a cell membrane because it contains the presences of proteins which are crucial to cell activity.
The refractory period for a membrane is the time it takes for the membrane to reset and be able to respond to another stimulus. During this period, the membrane is temporarily unable to respond to additional stimuli. This impacts the ability of the membrane to rapidly and continuously transmit signals, as it needs time to recover before it can respond again.
That's like asking why do we need skin or why do milk need cups or why bear needs skin. The cell membrane protects what is inside the cell and keeps it stable. Also, the cell membranes are selectively permeable and only not allows everything to let in the cell, but going back to the first reason, if cells did not have membranes, we would look like a slime.
In mammalian cells, the mitochondra, lysosomes and peroxisomes are ebveloped by a lipid containing membrant. None of the other orgenelles are membrane bound. In plants, the chloroplasts are bound by a membrane. None of the other orgenelles are covered by a membrane
The vacuole membrane, or tonoplast, helps maintain the structure and integrity of the vacuole by regulating the movement of substances in and out of the vacuole. It also plays a role in storing nutrients, maintaining turgor pressure, and facilitating waste disposal within the cell.
What seperates the internal composition and the Cytoplasme (the liquid inside the cell holding all parts or organisms of the cell in place) of the cell from the external is the plasmic membrane. This membrane has many functions as it's strcuture helps it to move or squeeze into places the cell needs to go.
yes plant cells needs a cell membrane
the cell membrane is like the skin of a cell. it keeps everything in that needs to be in and everything out that needs to be out.
Bells, the mall, even look on the internet,but nobody really needs a good dress. Youre already beautiful
a strong country needs a strong government, or it will collapse.
A cell membrane is like gate keeper because it needs to know that what substances enter or leave.
You can get a Larvesta Egg in a house in Route 18, if you have surf. Larvesta evolves to Volcarona, which is a really strong pokemon, but it needs a lot of training.
tell him that he is moving to fast for you and he needs to slow down. if he really loves you he WILL respect that.
You can get pet wipes for this purpose. They are available at pet supply stores. They work really well.
Strong smelling urine can occur from a few sources, my answer is incomplete but at least you'll have more info. If you are dehydrated or not drinking enough water. Depending on the smell. you have have an infection which really needs to be treated by a Dr.
stuff liek water and such that the cell needs to survive. the membrane is selective about what it allows in and out. bad stuff hardly ever makes it in.
no, because its liquid already.
Is Justin, will you wash the car it really needs it. A sentence?
