They are the flowering plants SUB DIVISION OF ANGIOSPERMAE INCLUDES: 1. Monocotyledon: They are plants with one seed leaf 2. Dicotyledon; They are plants with two seed leaves QUESTION 1 A. Use diagram to sketch the kingdom plantae B. Mention at least three features of the following i. Thallophyta ii. Bryophyta iii. iv. v. Dicotyledon Monocotyledon Gymnospermae
