Answer

1. Apical meristem - present at growing tips of stems and roots, increases length. 2. Lateral meristem (cambium) - increases girth of stem/root. 3. Intercalary meristem - located near nodes in some pl

Answer

Differentiation is the process by which cells formed by meristematic tissue take up a permanent shape, size, and function. During differentiation, cells lose their ability to divide and become special

Answer

Parenchyma: Living cells, thin walls, stores food, has intercellular spaces. Collenchyma: Living cells, irregularly thickened corners, provides flexibility and support. Sclerenchyma: Dead cells, thick

Answer

Chlorenchyma is parenchyma tissue that contains chlorophyll and performs photosynthesis. Aerenchyma is parenchyma tissue with large air cavities found in aquatic plants to help them float.
