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 cells 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 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.

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.

Vacuoles are absent in meristematic plant cell.

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.

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 cells lack vacuoles and intercellular spaces?

The meristematic tissue in plants lack vacuole and intercellular space.

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.

Why are intercellular spaces absent in Sclerenchyma?

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.

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 .

Why meristematic tissues have more cytoplasm?

Meristematic cells have a dense cytoplasm because they are actively dividing cells and have a high rate of respiration. ... These cells are very active and rapidly divide to form new cells, so the cells are constantly producing a lot of bio-molecules, making the cytoplasm very dense.

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.

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. ...

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 walls?

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.

Why is the nucleus of meristematic cells so large?

Answer: As the meristematic tissues have the function of the multiplication of the cells through the mitosis, therefore they have a large size of the nuclei as DNA is present in the nucleus which is the main reproductive site for the new cells.

What happens if meristematic tissue does not fulfill its function?

Meristematic tissues are primary growth tissue which consists of dividing cells that helps in the growth in the length, girth and internode length of the plants. But what if they don't fulfill its function. ... Hence, the plant will lack nourishment and water supply which will make lead to death of the plant.

Why do meristematic cells have a large nuclei?

because the meristematic cells have to divide in order to provide growth so they have a lot of activities related to cell division so they have a large nucleus to control all the activities related to cell division.

Do meristematic tissues have intercellular space?

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

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 is the function of 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. Sometimes a single vacuole can take up most of the interior space of the plant cell.

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.

Which of the following tissues has dead cells parenchyma Sclerenchyma Collenchyma epithelial tissue?

(b) Sclerenchyma cells are the permanent tissues present in the plants. They provide hardness and stiffness to the plant and are composed of dead cells. This tissue is present in stems around vascular bundles in the veins of leaves and in hard covering of seeds and nuts.

Which of the following is correct about meristematic tissue?

Answer : Meristematic tissue consists of cells which are not differentiated and which are cabable of cell division. It is found on those regions of the plant which grows.
