Distinguish between: a. radicle and plumule b. monocotyledonous and dicotyledonous seeds c. pollination and fertilization d. self-pollination and cross pollination e. maize seed and pea seed f. internal and external fertilization.
Understand the Problem
The question is asking to differentiate between various pairs of biological concepts, which involves explaining the distinct characteristics of each pair. This requires an understanding of key terms in plant biology.
Answer
Radicle is the root; plumule is the shoot. Monocots have one cotyledon; dicots have two. Pollination transfers pollen; fertilization fuses gametes. Self-pollination is within one flower; cross is between different plants. Maize is monocot; pea is dicot. Internal fertilization occurs inside; external outside.
a. Radicle develops into the root, while plumule develops into the shoot. b. Monocotyledonous seeds have one cotyledon, and dicotyledonous seeds have two cotyledons. c. Pollination is the transfer of pollen, and fertilization is the fusion of sperm and egg. d. Self-pollination occurs in the same flower; cross-pollination occurs between different plants. e. Maize seeds are monocot, while pea seeds are dicot. f. Internal fertilization occurs inside the organism, and external fertilization occurs outside.

More Information
Radicles are often the first to emerge during germination, anchoring the plant. Plumules help form leaves and stems crucial for photosynthesis. Monocots and dicots differ in seed structure, affecting their growth habits. Pollination and fertilization are separate yet sequential stages in plant reproduction.
Tips
Common mistake: confusing pollination (pollen transfer) with fertilization (actual fusion of cells). For seeds, remember the number of cotyledons: 'mono' for one and 'di' for two.
