     • Photosynthesis is really important for animals, including humans because without photosynthesis we wouldn’t have food because it converts energy from the sun into chemical energy for the food chains. photosynthesis keeps the levels of oxygen and carbon dioxide in the atmosphere in balance – without it we would very quickly run out of oxygen.

   What is a leaf cell?

   • A leaf cell, by definition, is any cell found within a leaf. However, there are many different kinds of leaf cell, and each plays an integral role in the overall function of the leaf and the plant itself. A single leaf cell may be designed to simply photosynthesize, or create sugars from the energy in light.

   How does a leaf cell work?

   • A single leaf cell may be designed to simply photosynthesize, or create sugars from the energy in light. Other cells are designed to carry these sugars to the phloem, a specialized tube for transporting the sugars to the rest of the plant. Still other cells are specialized to carry water, which eventually form a rigid tube, the xylem.

   How does a leaf carry out the process of respiration and photosynthesis?

   • to carry out the process of respiration and photosynthesis. Gases such as oxygen and carbon dioxide can travel through tiny holes underneath the leaf called Carbon dioxide diffuses into the cells found within the leaf to help carry out the process of photosynthesis, whilst oxygen is released from these cells as a product of photosynthesis.

   What is the structure of a leaf?

   • A typical leaf has an outer (epidermal) layer, pores (stomata) surrounded by a pair of guard cells, middle tissue (mesophyll) where photosynthesis occurs and a vascular system that carries water and nutrients. Life on Earth depends on the process of photosynthesis, which happens inside the cells of the humble leaf.

   Are leaf cells eukaryotic?

   • Like other plant cells, the leaf cell is eukaryotic. In addition to a nucleus within a membrane, a leaf cell has mitochondria, a central vacuole and sometimes chloroplasts containing cholorophyll. Cytoplasm is contained within a cell wall. Deciduous leaves are thin and flat to facilitate photosynthesis and respiration.

   Why do leaf cells form a protective layer over a leaf?

   • They form a protective layer over the leaf. They often produce waxy substances which protect the leaf from drying out or being attacked by insects. A leaf cell in the epidermis often lacks chloroplasts, the organelles responsible for creating sugar. The upper and lower epidermis vary slightly.

   Sep 21, 2021 · In plants, photosynthesis takes place primarily in leaves, which consist of many layers of cells and have differentiated top and bottom sides. The process of photosynthesis occurs not on the surface layers of the leaf, but rather in a middle layer called the mesophyll (Figure \(\PageIndex{6}\)).
