Study Notes

Plant Adaptations

Plant adaptations are specialized structures or features that help plants survive in specific environments.

Leaf Cell Conditions and Shapes

Leaf cells with many chloroplasts are typically found in leaves with a ** lanceolate** shape.
Leaves with few chloroplasts per cell are often circular or oval.

Plant Features and Functions

Stomata in the epidermis allow for gas exchange and contribute to the leaf's function.
Guard cells are located in the epidermis and control the opening and closing of stomata.
Bulliform cells are specialized cells found in the epidermis, which help to fold leaves when water is scarce.
Cuticle is a waxy layer on the surface of the leaf that prevents water loss, similar to human skin.

Leaf Adaptations and Environments

Xerophytic leaves are adapted to dry environments, with features such as thick cuticles and rolled leaves.
Hydrophytic leaves are adapted to aquatic environments, with features such as large air spaces and thin cuticles.
Mesophytic leaves are adapted to moderate environments, with features such as moderate cuticles and scattered air spaces.

Leaf Components and Descriptions

Palisade mesophyll is a layer of cells with many chloroplasts, where photosynthesis occurs.
Spongy mesophyll is a layer of cells with few chloroplasts, where gas exchange occurs.
Epidermis is the outer layer of the leaf, with stomata and guard cells.

Leaf Sections and Labels

Upper epidermis is the outer layer on the top of the leaf.
Lower epidermis is the outer layer on the bottom of the leaf.
Palisade mesophyll is the layer of cells with many chloroplasts.
Spongy mesophyll is the layer of cells with few chloroplasts.

Leaf Characteristics and Terms

Veins are the vascular tissues that run across the leaf blade.
Venation is the pattern of veins running across the leaf blade.
Simple leaf is a leaf with a single blade, as opposed to a compound leaf.
Pinnate leaf is a type of compound leaf with leaflets that occur in a featherlike pattern.

Plant Body and Stem

Shoot system includes all the stems and leaves of a plant.
Axillary buds are found at the joints of stems and are responsible for branching.
Primary root of most plants originates from the seedling.

Plant Structure and Function

Root system is the structure that comprises the architecture of most plants.
Stems are the primary supporting structures in plants, responsible for transporting water, nutrients, and sugars.
The main function of the cells with many chloroplasts is to carry out photosynthesis.
