Describe the structure, functions and adaptation of the following parts of a leaf : (a) cuticle (b) epidermis (c) guard cells d) palisade mesophyll . Four types and two undetermined types could be recognized: Type 1. 37. Palisade cells contain the largest number of chloroplasts per cell, which makes them the primary site of photosynthesis in the leaves of those plants that contain them, converting the energy in light to the chemical energy of carbohydrates. Multicellular organisms contain a wide range of different cells. Placeof Root HairCell o Where is it ? Palisade cells show various adaptations: first, their cylindrical shape, which allows maximum absorption of light by chloroplasts. Privacy: Your email address will only be used for sending these notifications. The mesophyll cells (more specifically, the spongy mesophyll) are surrounded by quite a lot of empty space for air to mingle around, providing plenty of surface area for gas exchange by diffusion. Leaf Palisade Cell Adaptations Photosynthesis The Palisade cell is very well adapted to efficiently carry out photosynthesis; the contain more chloroplasts than other plants cells, to help them with photosynthesis. These are the cells of the spongy parenchyma (or spongy mesophyll). O It is a thin thread like structure. asked in Leaves by Lifeeasy Biology 1 Answer 0 votes The palisade mesophyll cells are adapted for the main function of photosynthesis. In a xerophyte Genista tinctoria, the total cell volume, cell abundance, and the total surface area of cells and chloroplasts were 30–40% larger in the palisade than in the spongy mesophyll. Egg cells also form differently than sperm cells. All Email me at this address if a comment is added after mine: Email me if a comment is added after mine. 36. KS3 Xylem Vessel /Cell 35. Cell adaptation refers to the changes taking place in a cell in response to environmental changes. Diagram Cell Name Function Adaptations Root hair cell To absorb water and minerals from the soil. Palisade cells are found in the mesophyll of a leaf and their main function is the absorption of light so that photosynthesis can take place. (1 mark) (b) Palisade cells are found in leaves.
