Why do meristematic tissues lack vacuoles Meritnation?

Why do meristematic tissues lack vacuoles Meritnation?

Meristematic tissues are the type of tissue present in plants that divides continuously. To make the cell division easy the cells of meristematic tissues are small, very thin walled, and without any vacuoles. As the cells of meristematic tissues are dividing fast there is nothing to store.

Why do meristematic cells lack vacuoles and have prominent nucleus?

a) Meristematic tissue cells are continuously dividing and they have a prominent nucleus and a dese cytoplasm. Since they are diving rigorously they need not store food or waste products hence they lack vacuoles.

Do meristematic cells have a vacuole?

Meristematic cells have a prominent nucleus and dense cytoplasm but they lack vacuole.

Do meristematic tissues have large vacuoles?

Meristematic tissue is characterized by small cells, thin cell walls, large cell nuclei, absent or small vacuoles, and no intercellular spaces.

What happens if vacuoles are absent in leaf cells?

If a cell did not have a vacuole, then it would be unable to carry out its usual functions and would eventually die. In plants, the vacuole plays an important role in water storage and the maintenance of structure.

Why meristematic tissues have prominent nuclei?

Meristematic cells have dense cytoplasm and prominent nuclei because they are actively dividing cells ,so they require cytoplasm and nucleus to control their activities.

Does meristematic tissues lack vacuoles in its early stage?

Meristematic tissue lacks vacuole in its early stage. So, the correct answer is “Option C”. The apical meristem is responsible for the extension of the roots and shoots.

Do meristematic tissues lack vacuoles in its early stage?

Why do animal cells not need vacuoles?

Animal cells have a larger amount of vacuoles than plant cells, but they are much smaller. Animal cells lack the thick cell wall that plant cells have, so there is no need for a central vacuole to exert pressure on the surrounding cell.

Why do animal cells lack vacuoles?

In animal cells, vacuoles are present but are smaller in size compared to plant cells. Compared to other cells, animal cells have smaller vacuoles, as they do not require the storage of more water, organic and inorganic for the proper functioning of the cell. …

Why are meristematic tissues are aided with dense cytoplasm and prominent nucleus?

Meristematic cells have dense cytoplasm and prominent nuclei because they are actively dividing cells ,so they require cytoplasm and nucleus to control their activities. Vacuole has the function of storing food ,but in meristematic tissue ,cells keep on dividing and their is no need of storing anything.

What cells lack vacuoles and intercellular spaces?

The meristematic tissue in plants lack vacuole and intercellular space.

Why do meristematic tissues lack vacuoles?

why do meristematic tissue lack vacuole? Meristematic cells divide frequently and give rise to new cells and hence they need dense cytoplasm and thin cell wall. Vacuoles causes hindrance in cell division as it is full of cell sap to provide turgidity and rigidity to the cell.

Why do meristematic cells have a thin cell wall?

Meristematic cells divide frequently and give rise to new cells and hence they need dense cytoplasm and thin cell wall. Vacuoles causes hindrance in cell division as it is full of cell sap to provide turgidity and rigidity to the cell.

How do vacuoles cause hindrance in cell division?

Vacuoles causes hindrance in cell division as it is full of cell sap to provide turgidity and rigidity to the cell. Also vacuoles basically serve the purpose of storing of nutrients, excess salts etc. Meristematic cells do not need to store these nutrients as they have compact shape.

Why don’t plant cells have a central vacuole?

Plant cells usually have a large central vacuole which applies turgor pressure to keep the plant upright, as mentioned in one of your sources. The tips do not require to be very stiff and straight. So, a central vacuole is just not required. Also, meristematic cells grow various organelles as they mature.
