MDCAT Biology — Plant Biology
Plant Biology is a core Biology topic in the PMDC MDCAT syllabus, covering 9 subtopics. Below are the subtopics to revise, how often the topic appears in past papers, and real past-paper MCQs to try.
Subtopics (9)
- Angiosperms vs Gymnosperms
- Classification of Plant Kingdom (Bryophyta, Pteridophyta)
- Economic Importance of Plants
- Nutrition
- Photoperiodism and Phytochrome
- Plant Hormones (Auxins, Gibberellins, etc.)
- Reproduction in Angiosperms (Double Fertilization)
- Transport
- Water Movement in Plants (Guttation, Transpiration)
How Plant Biology is tested
Across the 16 MDCAT past papers on ParhaiKrlo, Plant Biology accounts for 16 questions. It appears in 4 of them, about 4 questions a paper. The heaviest was MDCAT 2008, with 9 questions, and the most recent is MDCAT 2011, with 1.
| Paper | Questions |
|---|---|
| MDCAT 2011 | 1 |
| MDCAT 2010 | 3 |
| MDCAT 2009 | 3 |
| MDCAT 2008 | 9 |
Plant Biology MCQs from the MDCAT past papers
Try each one before opening the answer. Each comes with a short explanation.
- Q1 · MDCAT 2011 · Plant Biology
Endosperm is formed as a result of
- A.Pollination
- B.Self-Pollination
- C.Double Fertilization
- D.Cross Pollination
Show answer
Answer: C. Double Fertilization — Endosperm (the nutritive tissue in a seed) forms as a result of double fertilization, a process unique to flowering plants (angiosperms).
- Q2 · MDCAT 2010 · Plant Biology
“Vascular System absent; gametophyte dominant, sporophyte attached to gametophyte; homosporous” are distinguishing characters of
- A.Psiolpsida
- B.Pteropsida
- C.Angiosperms
- D.Bryophyta
Show answer
Answer: D. Bryophyta — An absent vascular system, dominant gametophyte, sporophyte attached to and dependent on the gametophyte, and homospory are distinguishing features of Bryophyta (mosses, liverworts).
- Q3 · MDCAT 2009 · Plant Biology
The gymnosperms are called ‘Naked Seeded’ plants because they bear naked:
- A.Antheridia
- B.Ovules
- C.Fruits
- D.Archegonia
Show answer
Answer: B. Ovules — Gymnosperms are called 'naked-seeded' because their ovules (and resulting seeds) are not enclosed within an ovary/fruit, unlike angiosperms.
