A. BOT 110: What Makes a Plant?

Which pigment is primarily responsible for photosynthesis in plants?

All plants obtain all their amino acids from their environment.

What are the two stages of the alternation of generation in the plant life cycle?

Plants have ______ walls composed of cellulose and organic polymers.

Match the following cellular features with their function:

Which of the following is NOT a major anabolic pathway for plants?

Fruit helps in dispersing seeds through space.

What is the main purpose of plant secondary metabolites?

Cellular Features

Pigments play essential roles in photosynthesis and attraction:
- Chlorophyll: Vital for photosynthesis.
- Carotenoids: Aid in photosynthesis, provide photoprotection, and attract pollinators.
- Anthocyanin: Attracts pollinators and seed dispersers, provides photoprotection.
Anabolism: Plants synthesize all essential biomolecules including:
- Amino acids, proteins, lipids, nucleic acids, vitamins.
- Secondary metabolites for ecological functions.
- Major anabolic pathways occur in plastids.
Cell Walls:
- Nonliving material outside the plasma membrane.
- Composed of cellulose and other organic polymers, critical for land colonization.
- May contain active enzymes.

Use of Water

Plants utilize water and its properties uniquely for growth and physiological processes.

Alternation of Generations

Life cycle alternates between a haploid gametophyte and a diploid sporophyte.

Growth

New cells are produced in meristems throughout a plant's life cycle.

Morphoanatomy

Plant bodies consist of four main organs formed from three different tissue types.

Dispersal and Survival

Fruit aids in seed dispersal through space, while dormancy allows seeds to be dispersed over time.
Many plant reproductive strategies have coevolved with animal interactions.

This quiz explores the fundamental aspects that define a plant, including cellular features, growth mechanisms, and survival strategies. Dive into topics like chlorophyll, carotenoids, and the plant life cycle to enhance your understanding of botany.
