Botany Week 1 Lecture 1: Living Organisms Kingdoms

Multicellular, move with cilia or flagella = Animalia Acquire nutrients by absorption = Fungi Organelles including chloroplasts and cell walls = Plantae Mostly single-celled, may have chloroplasts = Protists

Asexual reproduction through binary fission = Protists Reproduce by means of spores or binary fission = Fungi Reproduce sexually by the fusion of gametes = Plantae Sexual reproduction observed rarely = Protists

Plants that live in moderate temperature = Mesophyll Plants that live in scarce water supply and dry conditions = Xerophytes Aquatic or water plants that live in extreme water conditions = Hydrophytes Plants that grow in salt or saline soils = Halophytes

<p>Single-celled organisms, may or may not move, no nucleus = Monera Single-celled organisms, move by cilia, flagella, or amoeboid mechanisms = Protista Absorb nutrients through cell wall or produce their own by photosynthesis = Monera Have a visible feeding mechanism and usually no cell wall = Protista</p> Signup and view all the answers

<p>Prokaryotic cells without nuclei and membrane-bounded organelles = Monera Eukaryotic cells with nuclei and membrane-bounded organelles = Protista Cells with no chloroplasts or other organelles = Monera Cells that usually move by cilia, flagella, or amoeboid mechanisms = Protista</p> Signup and view all the answers

<p>Fungi acquire nutrients by absorption from decaying material. Unlike plant-like protists, they do not perform photosynthesis, and unlike animal-like protists, they have no mechanisms for locomotion.</p> Signup and view all the answers

<p>Plant-like protists may reproduce asexually through binary fission, or sexually. Fungi reproduce by means of spores or binary fission, and also through sexual reproduction. Plants reproduce sexually by the fusion of gametes, and rarely reproduce vegetatively.</p> Signup and view all the answers
