Plants

The outer layer or part of an organism that comes in contact with the environment. In some higher plants, the is a water-impervious protective layer covering the epidermal cells of leaves and other parts and limiting water loss.

(a)  

• Cuticle
• Lower Epidermis
• Vein
• Guard Cells

______ cells are pairs of epidermal cells that control gas diffusion by regulating the opening and closure of stomatal pores. Guard cells, like other types of plant cells, are surrounded by a three-dimensional, extracellular network of polysaccharide-based wall polymers.

The lower half of the thickness of a leaf, consists of loosely arranged cells with large air spaces between them. This tissue functions essentially for the exchange of gasses: supply of carbon dioxide and the removal of oxygen.

• Xylem

• Palisade Parenchyma

NGSS.MS-LS2-3

_________ is the upper layer of ground tissue in a leaf. It is present in the upper epidermis. It consists of elongated cells. It is the primary area of photosynthesis as it contains chlorophyll.

• Vein

• Palisade Parenchyma

• Cuticle

• Upper Epidermis

NGSS.MS-LS1-6

The _________ cells do not contain chloroplasts and therefore do not go through photosynthesis. However, these cells are clear, allowing the light to pass through them and reach the cells underneath, enabling those cells to perform photosynthesis.

• Spongy Parenchyma

• Upper Epidermis

• Phloem

• Vien
