Epidermis – The leaf's outer layer and protective "skin" surrounding leaf tissues. Sausage-shaped cells that control the opening and closing of the stomata by changing shape due to external factors: 10: A pore in the leaf by which water vapor and carbon dioxide enter the leaf to be used for photosynthesis: 11 (black dots) Microscopic cells that contain chlorophyll and act as the food producers by executing photosynthesis The surface of many leaves is coated with a waxy cuticle which is secreted by the epidermis. Importance. Parts 4. The unique plant cell has similar parts and functions to an animal cell but a few distinct differences. epidermis - the protective, outler layer of cells on the surface of a leaf. Plant cell parts each have their own function, from the cell wall to the chloroplast. The stomata close in the night to retain gases and moisture in the leaf cells and opens during the day for gaseous exchange to continue. guard cell - one of a pair of sausage-shaped cells that surround a stoma (a pore in a leaf). Modification 6. Take a good look at the diagram and the various parts of the leaf … Except for the thylakoid membranes , where the clorophyll molecules reside, the rest of my colors are just there to help you see the parts, and to make pretty pictures. The guard cells (and stoma) are part of the epidermis. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Types 5. The whole leaf looks green to us, but most of the cells and cell material are colorless or clear. The mesophyll contains cells called chloroplasts, which convert sunlight into a stable chemical energy source the plant can utilize. Definition of Leaf: Leaf is a green, dissimilar exogenous lateral flattened outgrowth which is borne on the node of a stem or its branch and is specialised to perform photosynthesis. By Staff Writer Last Updated Mar 31, 2020 1:06:27 AM ET. Find these structures on the attached diagram of cellular leaf tissues. Lysosomes also use their hydrolytic enzymes to destroy pathogens (disease-causing organisms) that might enter the cell. Characteristics of Leaf 3. A leaf cell is a plant cell. Functions 7. Notably the presence of a more rigid cell wall and the modification to photosynthesize which requires chloroplast. Photosynthesis occurs primarily in the mesophyll, which is the middle layer of a leaf. protect the leaf against h20 loss, injury + disease: Cuticle: wax, protective covering/prevents h2o loss: waxy part: Stomates: openings in the lower epidermis, allow exchange of gases between external + internal environment: Guard Cells Definition of Leaf 2. In What Part of a Leaf Does Most Photosynthesis Occur? The green color comes from the chlorphyll molecules in the chloroplasts. In addition to their role as the digestive component and organelle-recycling facility of animal cells, lysosomes are considered to be parts of the endomembrane system. The leaf blade is composed of tissue layers, each having an important part to play in a functioning leaf. Below is a close diagram of the leaf structure: The basic structure of a leaf.
