What are the main differences between Monocots and Dicots?

Back

Monocots have one seed leaf (cotyledon), parallel leaf veins, and flower parts in multiples of three. Dicots have two seed leaves, branching leaf veins, and flower parts in multiples of four or five.

Front

Why are chloroplasts primarily found in the leaves of plants?

Back

Chloroplasts are found mostly in leaves because the large surface area allows for maximum light absorption, which is essential for photosynthesis.

What is the function of the vascular cambium in plants?

Back

The vascular cambium is a tissue layer that gives rise to secondary xylem (wood) and phloem (bark) in a stem, allowing for growth in thickness.

Front

How do you calculate the germination success rate of a plant species?

Back

Germination success rate is calculated by dividing the number of seeds that germinated by the total number of seeds planted, then multiplying by 100 to get a percentage.

Front

What is Macroevolution?

Back

Macroevolution refers to large-scale evolutionary changes that occur over long periods, leading to the emergence of new species and groups from a common ancestor.

Define photosynthesis.

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy, using carbon dioxide and water to produce glucose and oxygen.

What is the significance of the apical meristem in plant growth?

Back

The apical meristem is responsible for the vertical growth of plants, allowing them to grow taller and develop new leaves and flowers.

Front

Explain the term 'phylogeny'.

Back

Phylogeny is the study of the evolutionary history and relationships among species, often represented in a phylogenetic tree.

What is the primary function of xylem in plants?

Back

Xylem is responsible for the transport of water and dissolved minerals from the roots to the rest of the plant.
