Leaf and Light Vocab

Front

What is the job of pigment in plants?

Back

The job of pigment is to absorb light energy, which is essential for photosynthesis.

Front

What is the palisade layer in a leaf?

Back

The palisade layer is a layer of the leaf with closely packed, uniformly shaped cells located at the top of the mesophyll, where most photosynthesis occurs.

Front

What does ROY G BIV represent?

Back

ROY G BIV represents the colors of the visible spectrum: Red, Orange, Yellow, Green, Blue, Indigo, and Violet.

Front

What are stomata?

Back

Stomata are openings in the lower epidermis of leaves that allow for gas exchange, facilitating the intake of carbon dioxide and the release of oxygen.

Front

What is the function of the spongy layer in a leaf?

Back

The spongy layer is a part of the mesophyll that contains loosely packed cells, allowing for gas exchange and the diffusion of gases within the leaf.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight to synthesize foods with the help of chlorophyll, converting carbon dioxide and water into glucose and oxygen.

Front

What is chlorophyll?

Back

Chlorophyll is a green pigment found in plants that is crucial for photosynthesis, as it absorbs light energy.

Front

What is the epidermis in a leaf?

Back

The epidermis is the outer layer of cells covering the leaf, providing protection and helping to reduce water loss.

Front

What role do plastids play in plant cells?

Back

Plastids are organelles in plant cells that are involved in the synthesis and storage of food, including chloroplasts, which contain chlorophyll.

Front

What is the difference between the palisade layer and the spongy layer?

Back

The palisade layer consists of tightly packed cells for maximum light absorption, while the spongy layer has loosely arranged cells to facilitate gas exchange.
