Plants and photosyhtesis

• Photosynthesis is a chemical reaction that takes place in chloroplasts in plant cells carbon dioxide and water react to produce glucose and oxygen
• Leaves come in all different shapes and sizes, but their primary role is photosynthesis, which is why most leaves are green due to the abundance of the green pigment chlorophyll.
• The cross-section of a leaf shows the xylem and phloem on the bottom, and the epidermal layer on top.
• The epidermal layer covers the top and bottom of the leaf, and is responsible for allowing sunlight through for photosynthesis.
• The xylem and phloem are bundles of tubes that transport water and minerals throughout the leaf.
• The waxy cuticle is a layer at the top of the leaf that provides protection and prevents water loss.
• The spongy layer is a layer of cells above the bottom epidermal layer with lots of gaps in between, and is responsible for photosynthesis.
• The palisade layer is a layer of rectangular cells packed close together, and is also responsible for photosynthesis.
• The photosynthesis equation is: carbon dioxide plus water produces glucose plus oxygen.
• The stoma or stomata are the holes in the bottom of a leaf that allow gases to diffuse through, allowing carbon dioxide to diffuse in and oxygen to diffuse out.
• The spongy layer has lots of gaps, allowing gases to diffuse through.
• The xylem carries water from the roots to the leaf, which is needed for photosynthesis.
• The palisade layer is the most important for photosynthesis as it contains most of the photosynthesis.
• The guard cells on either side of the stomata control the opening and closing of the stomata.
• The palisade layer is packed with chloroplasts, which contain the green pigment called chlorophyll, needed to absorb sunlight.
• The phloem carries food, which is the glucose produced in photosynthesis, around the plant.
• The waxy cuticle on the top of the leaf prevents water loss, as the water taken in by the plant through the xylem is not lost through evaporation at the top of the leaf.
• Sunlight and chlorophyll are not written in the normal photosynthesis equation because they are not reacting or being produced, but both are needed for photosynthesis to happen.
• The structure of the leaf includes the epidermal layer that covers the leaf, the xylem and phloem on the bottom, and the spongy and palisade layers above.
• The epidermal layer is thin to allow sunlight through for photosynthesis.
• Leaves come in all different shapes and sizes, but their primary role is photosynthesis, which is why most leaves are green due to the abundance of the green pigment chlorophyll.
• The cross-section of a leaf shows the xylem and phloem on the bottom, and the epidermal layer on top.
• The epidermal layer covers the top and bottom of the leaf.
• The waxy cuticle is a part of the epidermal layer and can be felt on many leaves.
• The xylem and phloem are bundles of tubes found in the bottom of a leaf.
• The stoma, or holes, are found in the bottom of a leaf.
• Guard cells are located surrounding the stomata.
• The bottom epidermal layer, also known as the spongy layer, has many gaps in between cells.
• The palisade layer is a layer of rectangle cells packed close together.
• The phloem carries food, which is the glucose produced in photosynthesis, around the plant.
• The stoma or stomata are the holes in the bottom of a leaf that allow gases to diffuse through, allowing carbon dioxide to diffuse in and oxygen to diffuse out.

• root tissue absorbs water and mineral ions
