Tissues — Flashcards

Answer

A tissue is a group of cells that are similar in structure and work together to achieve a particular function. Example: Blood tissue transports substances throughout the body, muscle tissue helps in m…

Answer

In multicellular organisms, there are millions of cells. To perform different functions efficiently, cells specialize and group together to form tissues. This creates division of labor, where each tis…

Answer

1. Plants are stationary, so they have more supportive dead tissues; animals move, so they have more living tissues. 2. Plant growth is limited to specific regions (meristematic), while animal growth …

Answer

Meristematic tissue is the dividing tissue found in growing regions of plants. It has dense cytoplasm, thin cell walls, prominent nuclei, and lacks vacuoles. It's found at growing tips of stems and ro…

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.
