What is the apical meristem?
The apical meristem is a region of actively dividing cells at root and shoot tips responsible for primary growth (length).
-
Distinguish dicot and monocot roots in cross-section.
Dicot roots typically have a central vascular cylinder with alternating xylem and phloem; monocot roots often have a ring of alternating vascular bundles.
-
What is the function of phloem?
Phloem transports sugars, amino acids, and other organic solutes from sources (leaves) to sinks (roots, fruits).
-
What is the function of xylem?
Xylem transports water and dissolved minerals from roots upward through the plant.
-
What is the chemical equation for photosynthesis?
6CO₂ + 6H₂O + light energy → C₆H₁₂O₆ + 6O₂.
-
What are the two main stages of photosynthesis?
The light-dependent reactions (in thylakoids) and the Calvin cycle (light-independent reactions in the stroma).
-
What is photosynthesis?
Photosynthesis is the process by which green plants use light energy to convert CO₂ and water into glucose and oxygen.
-
What is the function of chloroplasts?
Chloroplasts capture light energy and convert it into chemical energy (ATP and NADPH) for photosynthesis.
-
Define a plant cell.
A plant cell is a eukaryotic cell with a cell wall, chloroplasts, a large central vacuole, and a nucleus.
-
What is botany?
Botany is the scientific study of plants, including their structure, growth, reproduction, metabolism, and classification.
