Study Notes
Plant Tissues
- Plant growth occurs only in specific regions where meristematic tissue is located.
- Meristematic tissue is classified into apical, lateral, and intercalary tissue based on the region where it is present.
- Apical meristem is present at the growing tips of stems and roots, increasing the length of the stem and root.
- Lateral meristem (cambium) increases the girth of the stem or root.
- Intercalary meristem is located near the node in some plants.
Characteristics of Meristematic Tissue
- Cells are very active with dense cytoplasm and thin cellulose walls.
- Very little intercellular space is present.
Types of Simple Tissues
- Parenchyma: thin-walled cells with large vacuoles.
- Collenchyma: cells with thick, irregular walls.
- Sclerenchyma: dead cells with long, narrow shapes and thick, lignified walls.
Tissue Functions
- Sclerenchyma tissue makes plants hard and stiff, found in stems, veins of leaves, and hard coverings of seeds and nuts.
- Areolar connective tissue provides support to internal organs, fills spaces, and aids in tissue repair.
Muscle Tissues
- Voluntary muscles are present in limbs and can be controlled by conscious will.
- Types of muscle tissues:
- Striated muscle: has striations, multiple nuclei, and nuclei at the periphery.
- Smooth muscle: has no striations, single nucleus, and nucleus at the center.
- Cardiac muscle: has striations, single nucleus, and nucleus at the center.
Nervous Tissue
- Highly specialized cells for being stimulated and transmitting stimuli rapidly.
- Nervous cells have extensions called dendrites.
