1) Thin - this allows carbon dioxide to easily diffuse into the leaf cells 2) Transparent epidermis - this allows light to reach the palisade cells 3) Large surface area - allows lots of light to be absorbed I mean I dont want to rush you or offend u in anyway. Hope this helps! Plants have two different types of 'transport' tissue, xylem and phloem. Updated: Jan 23, 2014. ppt, 3 MB. Hope this helps! It does this by diffusing through small pores called, tissue of the leaf. Leaves are suited for photosynthesis in a number of ways. Thin and transparent epidermis: - It allows more light to reach the palisade cells below.. Palisade mesophyll: - has cells vertically arranged such that many can fit into a small space. how is the structure of a palisade mesophyll cell specialised to support the process of photosynthesis? This needs light, carbon dioxide and water. It produces glucose, and oxygen as a by-product. Some of this water evaporates, and the water vapour can then escape from inside the leaf. Thanks for the feedback. which vascular tissues ( parenchyma, fiber, sclerenchyma, collenchyma ) contain greatest number of chloroplast ? When a plant is carrying out photosynthesis carbon dioxide needs to move from the air into the leaf. My main interests away from education are racing, rackets, real tennis and supporting the mighty Cobblers. May you shed more light on how we describe the light independent of photosynthesis. In doing so, this allows for the plant to gain resources more efficiently, primarily so that photosynthesis can be carried out, allowing the plants to carry out life processes and survive. ( Log Out /  Refraction of the rays must happen as well but cannot be significant as any refracted light will still pass through the upper epidermis into the palisade mesophyll. Spread the word! Carbon dioxide enters the leaf and oxygen and water vapour leave the plant through the. The only thing that’s wrong is that “transported” makes it sound like the plant is actively transporting the light through the epidermis. Hi Paul huge fan and this really helped me in my biology assignment. The adaptations of leaf for photosynthesis are: Large surface area for maximum light absorption. So air spaces in the leaf mean that carbon dioxide moves into leaf cells (mesophyll cells) faster than if there were no air spaces. The adaptations of leaf for photosynthesis are as follows: Leaves have chlorophyll i.e. Leaves are adapted to perform their function, eg they have a large surface area to absorb sunlight. They also show “cytoplasmic streaming” which is a process in which the cytoplasm rotates around the cell so every chloroplast is exposed to the same high light intensity at the top of the cell. Leaves shows following adaptations for photosynthesis
(a) Leaves provide large surface area for maximum light absorption. You need to understand the structure of the tissues in a leaf together with their functions. 830 views View 1 Upvoter But otherwise I think you are correct. Hope this helps! 5:13 100+ LIKES One of these adaptations, C4 type photosynthesis, will be covered in the photosynthesis lab. The leaf is the organ in a plant specially adapted for photosynthesis. The leaf is the organ in a plant specially adapted for photosynthesis. Created: Mar 31, 2010. The stomata are surrounded by guard cells, which control their opening and closing. the epidermal cells are transparent but is it considered as an adaptation for photosynthesis? This process is called photosynthesis. This site is really helpful, It has helped me answer my assignment without difficulties. Yes you are right but that is also what I said in the answer to the question. But guard cells do allow stomata to open and close and open stomata allow carbon dioxide to diffuse into the air spaces in the leaf during the day. Good luck with explaining this topic to other students – it is a tricky one…. Palisade cells are column shaped and packed with many. Lesson 2: Adaptation of the leaf Objectives: • Describe leaf adaptations for photosynthesis • Outline how raw materials needed for photosynthesis enter the plant. Photosynthesis and adaptations. 2. the main site for photosynthesis. Leaves are adapted for carrying out photosynthesis by virtue of their flat shape and periodic replacement, and because they contain most of the plant’s chlorophyll. Carbon dioxide is a gas found in air. Short distance for carbon dioxide to diffuse into leaf cells, Absorbs sunlight to transfer energy into chemicals, To support the leaf and transport water, mineral ions and sucrose (sugar), Allow carbon dioxide to diffuse into the leaf and oxygen to diffuse out. How are guard cells adapted to allow stomata to open or close? and what is the gas exchange between the air space and mesophyll? Resources: Structure of the leaf and stomata Ttructure and function of stomate 2 u see im a 7th grader and I dont understand this and I have to explain this to other students soooooo instead of answering my questions can u just explain i simpler words?

Leaves are adapted to carry out photosynthesis. This is because if the xerophyte has adapted to carry out photosynthesis in its stem, and in photosynthesis the gas exchange of carbon dioxide in and oxygen out is necessary. It produces a waxy layer, called the cuticle, which is not made of cells but is a waterproof barrier to prevent excessive evaporation through the hot upper surface of the leaf. About this resource.
