The ability of plants to form different structures in response to environmental changes or life phases.

Chloroplasts trap light energy for photosynthesis and contain structures called grana.

The process where glucose is broken down into pyruvate, involving ATP utilization and production.

A major pigment found in red algae that captures light for photosynthesis.

Members of this kingdom vary, with many being photosynthetic and some possessing silica cell walls.

Plant hormones that promote growth by elongating cells.

Plant hormones that regulate growth, including fruit and seed development.

Hormones that promote cell division and growth in plants, especially in roots.

A genus of plants known for their large, fern-like leaves and importance in cycads.

Organisms with a body cavity not completely lined by mesoderm, such as Aschelminthes.

A genus of giant trees known for their height and longevity, commonly found in North America.

The I-band shortens, A-band remains constant, and H-zone narrows during muscle contraction.

Serves as a neural link between various brain parts and moderates respiratory rhythm.

Specialized epidermal cells in plant leaves that manage water loss by curling leaves.

Flowers with a superior ovary, where other floral parts are attached below the ovary.

Endocrine glands secrete hormones and various enzymes into the bloodstream.

A type of epithelium that covers surfaces like skin and cavities with multiple cell layers.

The process in the electron transport chain where FADH2 donates electrons for ATP production.

A common method to evaluate scientific statements, where Assertion states a fact and Reason explains it.

A coenzyme that functions as an electron carrier during respiration, crucial for energy production.

The state of being swollen with water, which allows plant cells to maintain structure and support.

In dicot leaves, vascular bundles are surrounded by thick-walled cells.

Assertion (A) is true; Reason (R) is a correct explanation when both are true.

The arrangement of flowers on the floral axis.

Breaking C-C bonds during oxidation releases energy.
