What are the four types of meristematic tissue?
A plant has four kinds of meristems: the apical meristem and three kinds of lateral—vascular cambium, cork cambium, and intercalary meristem.
What type of cells are meristems?
Meristems are regions of unspecialised cells in plants that are capable of cell division. Meristems make unspecialised cells that have the potential to become any type of specialised cell. They are only found is certain parts of the plant such as the tip of roots and shoots and in between the xylem and phloem.
What are the three types of meristematic tissue class 9?
Types of meristematic tissue are apical meristem, Intercalary meristem, lateral meristem.
- Apical meristem is present on root and shoot tips of the plant.
- Intercalary meristem is present on leaf base and nodes.
- Lateral meristem is responsible for increase in circumference i.e. girth of the stem or root of the plant.
What is the other name of meristematic cells?
Meristematic tissue or meristems, as they are also called are tissues that have the ability to enlarge, stretch and differentiate into other types of cells as they mature.
What is a meristematic cell?
Meristematic tissues are cells or group of cells that have the ability to divide. These tissues in a plant consist of small, densely packed cells that can keep dividing to form new cells.
What is meristematic tissue give characters of meristematic cells describe different types of meristematic tissues?
Meristematic tissues contain living cells with varied shapes. They possess a large nucleus devoid of the vacuole. The cells have no intercellular space. The zone where these cells exist is known as meristem.
Are meristems stem cells?
Meristem cells are a group of cells that reside at the shoot and root tips of plants. As undifferentiated (or slightly differentiated cells) they are considered as stem cells given that they are the origin of many of the cells that go on to rapidly differentiate/specialize and form various parts of the plant.
How many types of meristems are present in plants on the basis of position?
three types
There are three types of meristem which are differentiated based on position of the meristem are apical meristem, intercalary meristem and lateral meristem.
What three kinds of tissues do meristems develop into?
Meristems produce cells that quickly differentiate, or specialize, and become permanent tissue. Such cells take on specific roles and lose their ability to divide further. They differentiate into three main types: dermal, vascular, and ground tissue.
Why do meristematic cells have large nuclei?
Secondly, why meristematic cells have large nuclei? 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.
Why do meristematic cells lack vacuoles?
Meristematic cells have a prominent nucleus and a dense cytoplasm but lack a vacuole, this is so because meristematic cells have an ability to divide and form new cell. Vacuoles have a function of storing food and other nutrients that a cell might need to survive.
What occurs as meristematic cells mature?
They stretch, enlarge and differentiate into other types of tissues as they mature. Meristematic cells are generally small and cuboidal with large nuclei, small vacuoles, and thin walls. A plant has four kinds of meristems: the apical meristem and three kinds of lateral-vascular cambium, cork cambium, and intercalary meristem.
What are the three types of meristematic tissue?
There are three types of meristematic tissues: apical (at the tips), intercalary (in the middle) and lateral (at the sides). At the meristem summit, there is a small group of slowly dividing cells, which is commonly called the central zone.
