What are the parts of a leave involved in photosynthesis?
The main parts of a leaf involved in photosynthesis are the chloroplasts, where photosynthesis occurs, and the stomata, which regulate gas exchange for photosynthesis. The mesophyll cells contain the majority of the chloroplasts where photosynthesis takes place, while the veins in the leaf provide the transport system for water and nutrients needed for photosynthesis.
What is the functiion of the phloem?
Phloem: tubes that usually move sap, with dissolved sucrose, produced by photosynthesis in the leaf, out of the leaf and to other parts of the plant.
What does phloem carries?
Phloem: tubes that usually move sap, with dissolved sucrose, produced by photosynthesis in the leaf, out of the leaf and to other parts of the plant.
How do parts of the leaf help with photosynthesis?
The cells in the leaf called chloroplasts contain chlorophyll, a pigment that absorbs sunlight. The stomata in the leaf allow for the exchange of gases, such as carbon dioxide and oxygen, needed for photosynthesis. Veins in the leaf deliver water and nutrients to the cells involved in photosynthesis.
What was the purpose of keeping the leaf in the dark and then covering it with a cardboard cut-out?
The purpose of keeping the leaf in the dark is to prevent photosynthesis from happening. By covering it with a cardboard cut-out with a specific design, you can control which parts of the leaf are exposed to light, allowing for experiments on the effects of light on photosynthesis in different areas of the leaf.
How is the sugar produced by photosynthesis transported from the leaf?
The sugar produced by photosynthesis in the leaf is transported through a network of tubes called phloem. These tubes carry the sugar to other parts of the plant where it is needed for energy or storage.
What is the function of spongey mesophyll in a leaf?
The spongy mesophyll in a leaf functions in gas exchange and photosynthesis. Its loosely packed cells allow for the diffusion of gases, such as carbon dioxide and oxygen, into and out of the leaf. Additionally, it contains chloroplasts that aid in photosynthesis by capturing light energy and converting it into sugars.
What are the organs in which plants carry out photosynthesis?
Plants carry out photosynthesis primarily in their leaves. Specifically, photosynthesis occurs in the chloroplasts within the leaf cells. The main organs involved in photosynthesis are the leaves, but other green parts of the plant like stems and even unripe fruit can also perform photosynthesis to some extent.
Enumerate the internal parts of a leaf?
The internal parts of a leaf include the epidermis (upper and lower layer), mesophyll (palisade and spongy layers), stomata, chloroplasts, veins (xylem and phloem), and the cuticle. These parts work together to facilitate processes such as photosynthesis, gas exchange, and transpiration.
Why do only some parts of a variegated leaf make starch?
Only the green parts of variegated leaves contain chlorophyll, which is necessary for photosynthesis to produce starch. Without chlorophyll, the non-green parts lack the ability to photosynthesize and make starch. This results in only the green areas of the variegated leaf being able to produce energy through photosynthesis.
What job does a vessel tissue in a leaf do?
Vascular tissue in a leaf, such as the xylem and phloem, helps transport water, nutrients, and sugars throughout the leaf for photosynthesis and growth. Xylem transports water and minerals from the roots to the leaves, while phloem transports sugars produced by photosynthesis to other parts of the plant.
