Meristematic cells are the cells that divide frequently. These cells need dense cytoplasm and thin cell walls. ... For this purpose, they have dense cytoplasm and thin cell walls. Due to this reason, meristematic cells lack vacuole.

Why do meristematic tissues lack vacuoles Class 9?

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. ... Meristematic cells do not need to store these nutrients as they have compact shape.

Why meristematic tissues lack vacuoles Brainly?

meristematic tissue lack vacuole becoz meristematic tissue need cytoplasm And thin cell wall . vacuoles cause hindrance in cell wall...

Why do meristematic tissues have dense cytoplasm and no vacuoles?

Meristematic cells have a prominent nucleus, dense cytoplasm and lack vacuoles and are because: these cells do not store food material or waste materials. Hence they lack vacuole. As vacuoles possess cell sap and provide rigidity and turgidity to the cell.

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.

Why do meristematic tissues have a large 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.

What cells lack vacuoles and intercellular spaces?

The meristematic tissue in plants lack vacuole and intercellular space.

Which of the following lacks vacuoles in cytoplasm?

Meristematic cells have a prominent nucleus and dense cytoplasm but they lack vacuole. Hint:Meristem is a type of tissue that is found in plants.

Why do meristematic tissues have thin cell wall?

As the meristmatic tissue divides repeatedly they need more organelles to share them with daughter cells . They have thin wall as wall breaks repeatedly for cell division . Nuclei are large so that when it will divide then it can be in sufficient amount in all offsprings.

What happens to the cells formed by meristematic tissue?

Answer: The cells formed by meristematic tissue take up a specific role and lose their ability to divide. As a result, they form a permanent tissue. This process of taking up a permanent shape, size and function is called differentiation.

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.

What is the function of vacuole in plant cell?

​Vacuole. A vacuole is a membrane-bound cell organelle. In animal cells, vacuoles are generally small and help sequester waste products. In plant cells, vacuoles help maintain water balance.

What is lacking in the marriage Matic tissue from the following?

(d) Meristematic tissues, in its early stage, lack vacuoles. Answer: (c) Parenchyma serves as a packing tissue in plants therefore they do not have intercellular spaces.

Why there are no vacuoles in the intercalary meristem?

vacuoles are responsible for storage of food and water the intercalary tissue do not store them the vacuoles contain with sap provide rigidity to SAP. ... hence, vacuoles are not present in them .

Does meristematic tissue have a vacuole?

Meristematic cells have a tremendous ability to divide. They have dense cytoplasm and a thin cell wall for this purpose. Meristematic cells, as a result, lack a vacuole.

Why vacuoles are absent in animal cell?

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. ...

Do meristematic tissues have thin cell wall?

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

Do meristematic tissues have thick walls?

Thick cell walls, no nucleus and large intercellular spaces.

Do meristematic tissues have cell wall?

Meristematic cells are packed closely together without intercellular spaces. The cell wall is a very thin primary cell wall.

Which type of tissue have dense cytoplasm thin cellulose walls prominent nuclei and lack vacuoles?

Cells of meristematic tissue are very active,they have dense cytoplasm, thin cellulose walls and prominent nuclei. They lack vacuoles.

What is the role of epidermis in plants II give reasons for meristematic cells have a prominent nucleus and dense cytoplasm but they lack vacuole?

The meristematic cell can divide themselves. So they do not need vacuole but require nucleus and thus lack vacuoles. Whereas in sclerenchymatous tissues, no growth or division take place . They only help in providing mechanical support to the plant.

What is the meaning of dense cytoplasm?

The fluid (gel) like substance inside the cell in which organelles are present is called the cytoplasm. When the contents of cytoplasm are closely compacted together, it is termed as dense cytoplasm.

Why intercellular spaces are absent in Sclerenchyma tissue?

Intercellular space is lacking in sclerenchyma tissue because the cells are dead and the cell walls have thickened due to the deposition of lignin, which functions as a cement.

Which of the following is not a function of the vacuole in plants?

Osmotic pressure and turgidity is maintained by vacuoles. They store toxic metabolic by-products or end products of plant cells. Such vacuoles are thrown out of the cell by exocytosis. Thus, the incorrect answer is option B.

What will happen if the tip of sugarcane plant is removed?

Meristem cells have the ability to proliferate and generate new cells. Sugarcane is a monocot plant with nodes that have intercalary meristems. As a result, even if the sugarcane's tip is cut, it can still grow because of the intercalary meristem found at nodes.
