What is photosynthesis?

The process by which green plants use sunlight to synthesize foods with the help of chlorophyll.

What role do chloroplasts play in plants?

Chloroplasts are the organelles where photosynthesis occurs, converting light energy into chemical energy.

Define a monocot plant.

A plant that has one cotyledon in its seed, parallel leaf veins, and flower parts usually in multiples of three.

What characterizes dicot plants?

Dicots have two cotyledons in their seeds, net-like leaf venation, and flower parts usually in multiples of four or five.

What is the primary function of plant roots?

Roots anchor the plant in the soil and absorb water and nutrients from the ground.

What are stomata?

Small openings on the surface of leaves that facilitate gas exchange, allowing CO2 in and O2 out.

What is transpiration in plants?

The process of water movement through a plant and its evaporation from aerial parts, mainly leaves.

Describe the function of xylem in plants.

Xylem tissue transports water and dissolved minerals from the roots to the rest of the plant.

What is phloem responsible for?

Phloem transports organic compounds, especially sugars, produced by photosynthesis to different parts of the plant.

What is the purpose of plant hormones?

Plant hormones regulate various functions, including growth, development, and responses to environmental stimuli.

What do plant cells have that animal cells do not?

Plant cells have a cell wall, chloroplasts, and large central vacuoles.

Define photosystems.

Photosystems are complexes of proteins and pigments that capture light energy for photosynthesis.

Describe the function of chlorophyll.

Chlorophyll is the green pigment in plants that absorbs light energy for photosynthesis.

What is the role of guard cells?

Guard cells control the opening and closing of stomata, regulating gas exchange and transpiration.

What is the significance of root nodules?

Root nodules, often found in legumes, house nitrogen-fixing bacteria that convert atmospheric nitrogen into a usable form.

Explain the process of germination.

Germination is the process by which a seed develops into a new plant.

What is the function of the cuticle in plants?

The cuticle is a waxy layer on leaves that reduces water loss.

What are mycorrhizae?

Mycorrhizae are symbiotic associations between fungi and plant roots, enhancing nutrient absorption.

What role do auxins play in plant growth?

Auxins are hormones that promote cell elongation and coordinate growth and responses to light.

Define phototropism.

Phototropism is the growth of a plant toward a light source.
