Leaf adaptations - Study guides, Revision notes & Summaries

AQA A LEVEL BIOLOGY Paper 1 2024 What is the function of the cell membrane? - ANS To control what enters and leaves the cell, acts as a barrier between the cell and its environment. What structural feature of the cell membrane allows substances to enter/leave? - ANS Partially permeable What is the fluid mosaic model? - ANS States that a membrane is a fluid structure (because phospholipids are constantly moving) with a "mosaic" of various proteins embedded in it Describe the...

How does the arrangement of dermal tissues and ground tissues serve the leaves which are said to be ideally suited for photosynthesis - Answer - Epidermis is thin and transparent= allow more light to reach the palisade cells - Palisade cell layer at top of leaf= To absorb more light - Spongy layer= Air spaces allow carbon dioxide to diffuse through the leaf, and increase the surface area - The flat, thin shape of a leaf, its spongy mesophyll layer and stomata are adaptations that also all...

Land Plants Complex multicellular organism that range in size from minute to MASSIVE. Adaptations of this type of plant include anatomical, physiological, and reproductive features. Waxy Cuticle Covers aerial portions of a plant, protects against water loss. Resides ON TOP of the epidermis. Stomata Used for gas exchanged, required for photosynthesis. Guard Cells surround this and can open or close it depending on environmental/chemical interactions. Antheridia Gametangia that produce SPER...
