Anatomy - Root & Shoot — Flashcards

Answer

Plant anatomy is the study of the internal structure of plants, including tissues and cells in organs like roots, stems, and leaves. It helps us understand how different tissues are arranged and how t…

Answer

Roots: absorb water and minerals, anchor the plant. Stem: supports the plant, transports water and nutrients. Leaves: perform photosynthesis. Flowers: involved in reproduction. Fruits: protect and dis…

Answer

Epiblema is the outermost single layer of thin-walled cells in a dicor root. Some cells form unicellular root hairs that absorb water and minerals from the soil. It also provides protection to the inn…

Answer

The cortex is a large, multi-layered zone made of thin-walled parenchymatous cells with intercellular spaces. It stores food and water and helps in radial conduction of water from the epiblema to the …

Answer

Casparian strips are band-like thickenings made of suberin found on the radial walls of endodermal cells in roots. They prevent water from moving through the cell walls and force it to pass through th…

Answer

The endodermis regulates the movement of water and dissolved salts into the vascular cylinder. Due to Casparian strips, it acts as a selective barrier, ensuring only necessary substances enter the xyl…

Answer

The stele is the central part of the root, located inner to the endodermis. It includes the pericycle, vascular bundles (xylem and phloem), and sometimes pith. It is responsible for transport and give…

Answer

The pericycle is a single layer of cells inside the endodermis. It gives rise to lateral roots and the vascular cambium during secondary growth, playing a key role in root development and thickening.
