Study Notes
Muscle Tissues
- Smooth muscles are found in the iris of the eye, ureters, and bronchi
- Smooth muscle cells are long with pointed ends, and are uninucleate
- Smooth muscles are also called unstriated muscles
- Cardiac muscles are found in the heart
- Cardiac muscles show rhythmic contraction and relaxation throughout life
- Cardiac muscles are involuntary.
- Cardiac muscles are cylindrical, branched, and uninucleate
Nervous Tissue
- Nervous tissues are specialized to respond to stimuli and transmit the stimulus rapidly
- All cells have the ability to respond to stimuli
Plant Tissues
- Epidermis is the outermost layer of cells in plants
- In plants living in dry habitats, the epidermis is made of a single layer of cells
- Cork cells are dead, compactly arranged, and lack intercellular spaces
- Cork cells have suberin in their walls making them impervious to gases and water.
- Phloem cells are living cells except for phloem fibers
- Xylem consists of tracheids, vessels, xylem parenchyma, and xylem fibers.
- Xylem cells have thick walls, and many are dead.
- Tracheids and vessels are tubular structures that transport water and minerals vertically
- Xylem parenchyma stores food and helps in the sideways conduction of water.
- Phloem is made up of sieve tubes, companion cells, phloem fibers, and phloem parenchyma
- Sieve tubes are tubular cells with perforated walls
- Phloem unlike xylem allows materials to move in both directions
Meristematic Tissue
- Apical meristem is located at the growing tips of stems and roots
- Apical meristem increases the length of stems and roots
- Lateral meristem increases the girth of stems and roots
- The intercalary meristem is located at the base of leaves or internodes
- Meristematic tissues have cells with dense cytoplasm, thin cellulose walls, and prominent nuclei
- Meristematic tissues lack vacuoles
Permanent Tissue
- Permanent tissues lose the ability to divide and take up a specific role.
- Permanent tissues are formed from meristematic tissues
Simple Permanent Tissue
- Simple permanent tissues are made of one type of cell
- Simple permanent tissues coordinate to perform a common function
Complex Permanent Tissue
- Complex tissues are made up of more than one type of cell.
- Xylem and phloem are examples of complex tissues
- Xylem and Phloem constitute a vascular bundle
- Vascular tissue is a distinctive feature of complex plants.
- Xylem transports water and minerals
- Phloem transports food from leaves to other parts of the plant
Tissues in Animals and Plants
- Animals and plants have different structures and perform different functions
- Plant and animals have different modes of life
- Animals and plants have different feeding methods
- The structural organization of organs and organ systems is more specialized in animals than in plants
