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 tissue have no vacuoles?

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.

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.

Which tissues do not have vacuoles?

Meristematic cells are mainly concerned with cell division. Their primary function is mitosis. They do not have any waste material to store so vacuoles are usually absent in the meristematic cells.

Do meristematic tissue in its early stage lack vacuoles?

Meristematic tissues are not permanent tissues because permanent tissues do not divide after differentiation. For example, permanent tissues are parenchyma, collenchyma, xylem, phloem, etc. ... Meristematic tissue lacks vacuole in its early stage. So, the correct answer is “Option C”.

Why vacuoles are absent in animal cell?

Animal cells have smaller vacuoles than other cells since they don't need to store as much water, both organic and inorganic, for proper operation. It's partly due to the inevitable evolutionary trade-off. Animal cells are part of a bigger organism that can relocate to find water, food, and other necessities.

Why there are no vacuoles in the intercalary meristem?

Explanation: 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 .

What happens if meristematic tissue is absent in plants?

Answer: If meristematic tissues are not present, the growth of the plants would be stop. Because meristematic tissues consist of dividing cells and are present at growing points of plants. These are responsible for the growth of plants.

What are the types of permanent tissue?

Simple permanent tissues are again classified into three main types. They are parenchyma, collenchyma, and sclerenchyma.

What are meristematic and permanent tissue?

Meristematic tissues in plants consist of a mass of undifferentiated cells whose main function is to participate in plant growth. Permanent tissues, on the other hand, are differentiated tissues, carrying out dedicated functions.

What is the function of vacuoles?

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 is permanent tissue?

Permanent tissues are made up of cells that do not undergo cell division. The cells in these tissues are modified to perform some specific functions. The cells in permanent tissues are fully grown, bigger in size, and have a certain shape. ... Permanent tissues are derived from the meristematic tissue.

What are the characteristics of meristematic tissue?

Characteristics of Meristematic Tissue:
  • They are composed of immature cells. ...
  • Absence of intercellular spaces.
  • Cells are oval, rounded or polygonal in shape.
  • Cells are always living and thin walled.
  • Cells are rich in cytoplasm with minute vacuoles. ...
  • Cell is diploid and shows mitotic cell division.

Why do meristematic cells 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.

What happens to the cell formed by meristematic tissue?

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.

Do meristematic cells have nucleus?

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

What is function of permanent tissue?

Functions of Permanent Tissues

The permanent tissues store the food materials such as starch, proteins, fats and oils. They show essential metabolic functions like respiration, photosynthesis, secretion, etc. Chlorenchyma helps in photosynthesis, and aerenchyma helps in buoyancy and gaseous exchange.

Which is not a permanent tissue?

Collenchyma is simple tissue since it consists of only one type of cells, that is the collenchyma cells. The collenchyma is living cells, with actively dividing protoplasm. Hence it is not a permanent tissue.

What is permanent tissue give its characteristics?

Characteristic features of permanent tissues: (i) Cells may be living or dead. (ii) Cell walls may be thin or thick. (iii) Cells may contain reserve, excretory or secretory substances. (iv) Intercellular spaces may be present or absent.

What is the main function of meristematic tissue?

Meristematic tissues are responsible for plant growth. They are present at the tips of roots,stem and branches. The cells present in these tissues constantly divide to produce new cells. The cells actively divide to produce new cells.

Which one of the following is absent in meristematic tissue?

Meristem tissue and plant development

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

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 does girth of stem increase?

Explanation: The increase in the girth of a stem or secondary growth takes place due to the presence of lateral meristem, cork cambium, and vascular cambium. Apical meristems are found on the apices / growing parts of a plant such as tips of shoots, roots, etc.

Why do meristematic cells have 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.

Why are the vacuoles present in the meristematic cells?

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. Also vacuoles basically serve the purpose of storing of nutrients, excess salts etc.
