29
Q

Apical - root apex; growing points: upward and downward growth direction
Lateral- sides of roots, stems, etc; sideward growth
Intercalary- internodes

A

Meristematic tissues - actively dividing cells

30
Q

SIMPLE TISSUES: only one type of cells
*Parenchyma: fleshy parts and seat of activities like photosynthesis and metabolism

*Collenchyma: thick walled, elongated cells with unevenly thickendened primary walls , mechanical support (early growth)

*Schlerenchyma: thick walled, heavily lignified and non-living when mature. (gritty texture of chico fruit)

A

Permanent tissues - mature, fully differentiated cells

31
Q

COMPLEX- composed of two or more types of cells

*Phloem: plant food (sieve tube, companion cells, ray cells, fiber, and parenchyma cells)

*Xylem: water (tracheids, vessel, element, fiber, ray cell, and parenchyma cells)

A

PERMANENT TISSUES

32
Q

Above ground

Below the ground
*Bulb - scales: onions, daffodils, hyacinth , garlic (compound)
