N Gew
What is the branch of biology that studies tissues called?
Histology
How are tissues broadly categorized?
- Plant tissues
- Animal tissues
What type of cells predominantly make up plant tissues?
Most are dead cells that provide mechanical strength
What are the three types of meristematic tissue?
- Apical meristem
- Lateral meristem
- Intercalary meristem
What is meristematic tissue?
Tissue that remains in a continuous state of division or retains the power of division
What is the main function of meristematic tissue?
To divide and form new cells that differentiate into permanent tissues
Where are meristematic tissues generally found in plants?
- Apex of the root
- Axis of stem
- Cambium
What are the characteristics of meristematic tissue?
- Cells may be rounded, oval, polygonal, or rectangular
- Cells are similar in appearance to older meristematic cells
- Cells change characteristics as they mature
What are the two main categories of plant tissue?
- Simple tissue (made up of one type of cells)
- Complex tissue (made up of many kinds of cells)
What is an example of simple tissue in plants?
- Parenchyma
- Collenchyma
- Sclerenchyma
True or False: Most plant tissues are living cells.
False
What does complex tissue in plants consist of?
Many kinds of cells
Fill in the blank: The meristematic tissues divide to form new cells, which differentiate to give rise to _______.
