Root tip magnified 100×. 1. Meristem 2. Columellae (statocytes with statolithes) 3. Lateral part of the tip 4. Dead cells 5. Elongation zone. The root cap is a type of tissue at the tip of a plant root. [1] It is also called calyptra. Root caps contain statocytes which are involved in gravity perception in plants. [1]
Plant anatomy or phytotomy is the general term for the study of the internal structure of plants.Originally, it included plant morphology, the description of the physical form and external structure of plants, but since the mid-20th century, plant anatomy has been considered a separate field referring only to internal plant structure.
The quiescent centre is a group of cells, up to 1,000 in number, in the form of a hemisphere, with the flat face toward the root tip of vascular plants. [1] It is a region in the apical meristem of a root where cell division proceeds very slowly or not at all, but the cells are capable of resuming meristematic activity when the tissue surrounding them is damaged.
The SAM is located at the tips of shoots and produces leaves, stems, and flowers, while the RAM is found at the tips of roots and generates new root tissues. Both types consist of rapidly-dividing cells that remain indeterminate, meaning they continuously produce new cells without a predefined final state, similar to stem cells in animals ...
English: A simple diagram of a plant leaf cell, labelled with numbers. It shows the cytoplasm, nucleus, cell membrane, cell wall, mitochondria, permanent vacuole, and chloroplasts. Note going down the left the numbers are not sequential, this is to match the numbering on others in the series.

The loosely packed cells of root cortex allow movement of water and oxygen in the intercellular spaces. [4] One of the main functions of the root cortex is to serve as a storage area for reserve foods. [4] The innermost layer of the cortex in the roots of vascular plants is the endodermis. The endodermis is responsible for storing starch as ...
Runner – an elongated, slender branch that roots at the nodes or tip. Stolon – A branch that forms near the base of the plant, grows horizontally, and roots and produces new plants at the nodes or apex. Stoloniferous – plants producing stolons. Semi-erect – Not growing perfectly straight.
