Plant Organs: The Leaf and Its Functions

Chloroplasts can change their shape and location in a cell to decrease the amount of light they capture.

Xylem cells are lined with cellulose.

Root hairs are responsible for storing starch in plants.

Taproots are thinner and spread out horizontally.

Phloem is not porous, which limits exchanges between phloem and neighboring cells.

Stems have two main functions: support and transportation of water nutrients and sugars.

During cell differentiation, all DNA in a cell is active.

Specialized cells in plants are constantly dividing.

Organs in plants include roots, leaves, and flowers.

Plants can reproduce some organs at any time, unlike animals.

When the terminal bud is removed from a plant, it grows up more due to increased auxin production.

If lateral buds on a plant are active, it means the terminal bud is producing auxin.

The leaf's main function is to store excess glucose as starch.

The upper leaf surface is mainly composed of palisade tissue.

The lower leaf surface is impermeable to gases.

Xylem in the leaf delivers water in the form of sugar.

Guard cells on the lower leaf surface control the opening and closing of stomata.

The center of the leaf consists of spongy parenchyma cells.
