Meristems producing new buds or root extensions?
Apical Meristems form root extensions. Apical meristems dont produce new buds but they are found in the terminal and axillary buds.
What is floral evocation?
Early processes that take place in the shoot apex that lead to a commitment of the shoot apical meristem to form floral meristems that develop into flowers.
Where is the meristem located?
Groups of cells that are the source of new cells form tissue called meristem. Meristem cells aren't specialized, but when they divide, some of the new cells specialize into tissues. Areas of growth that lengthen the tips of roots and stems are called apical meristems. Lateral meristems, found all along woody roots and stems, increase the thickness of these plant parts.
What kind of cells undergo mitosis?
nohing
What is produced in meristems?
gibberellins
Meristems producing new buds or root extensions?
Apical Meristems form root extensions. Apical meristems dont produce new buds but they are found in the terminal and axillary buds.
What are plant tissues that produce new cells by mitosis called?
Plant tissues that produce new cells by mitosis are called meristems. Meristems are found at the tips of stems and roots, and they are responsible for the continuous growth of plants throughout their lifespan. Depending on their location, meristems can be classified as apical meristems (at the tips) or lateral meristems (on the sides).
Can primary growth occur at both the apical and lateral meristems?
The difference between apical meristems and lateral meristems are the location that they sprout buds on plants. Apical buds are present at the top of plants, while lateral buds are present at the base of plants.
What are the sites of cell growth in plants called?
They are called meristems or apical meristems when they are located at the tips of roots.
Where else on many plants is there meristematic tissue other than at apical meristems?
it can also be found in lateral and intercalary meristems
Where does the growth in a tree occur?
Trees grow by producing new cells in a very limited number of places. These places of cell division are called meristems. Meristems are zones of intense activity. They are where all new cells are formed and where they expand. Trees grow in height as a result of meristems that are located at their branch tips. These meristems are called apical meristems. Roots also expand through the soil by growing at their tips as a result of apical meristems. All buds that you see on a tree contain apical meristems. Trunk diameter growth occurs as a result of another meristem already mentioned called the vascular cambium. The vascular cambium produces new xylem and phloem each year and as a result the trunk, branches and roots continue to increase in diameter.
What is difference between intercalary meristem and lateral meristem?
Apical meristems :- Apical meristems are present at the apices(tips) of roots and shoots. They are concerned with the extension of plant length. They cause increase in plant length, so, they play important role in primary growth.. Lateral meristems :- Lateral meristems are the meristems present in roots, stems and branches. In transverse section, there position is away from centre. Examples :- Vascular and Cork cambium Functions :- Concerned with secondary growth. Intercalary meristems :- These are the parts of apical meristems separated by sheet of permanent cells. These are situated at base of internodes in most plants. These meristems are responsible for production of new leaves and flowers 💐... Regardz Princeovpaghals
Which plant hormone produced in apical meristems inhibits the growth of axillary buds?
The class of hormones called "Auxins" have this affect on plants.
Plant meristems produce new cells by which of these processes?
the answer is mitosis
What three characteristic scienctics use to define a true plant?
1) Multicellular, dependent embryos 2) Apical meristems 3) Walled spores produced in sporangia
How are meristems in plants similar to and different from stem cells in animals?
Similarities: They both have 2 types of stem cells Differences: Apical meristem increases length and lateral increases width whereas in animals they become specialized cells to increase the efficiency of the systems in the body. in plants apical and lateral meristems can differentiate into any kind of cell whereas in animals only embryonic stem cells can do that not tissue stem cells.
What is floral evocation?
Early processes that take place in the shoot apex that lead to a commitment of the shoot apical meristem to form floral meristems that develop into flowers.
