Algae Flashcards
What type of reproduction involves the fusion of two gametes dissimilar in size?
Anisogamous
Example: Eudorina exhibits anisogamous reproduction.
What is the term for the fusion of two gametes that are similar in size?
Isogamous
Example: Spirogyra reproduces isogamously.
What type of reproduction occurs through fragmentation in algae?
Vegetative reproduction
Each fragment develops into a new plant.
What are the common types of spores produced by algae?
Zoospores
Zoospores are flagellated and are commonly produced in asexual reproduction.
What are the two primary methods of reproduction in algae?
Asexual and sexual methods
Algae can reproduce vegetatively, asexually, or sexually.
What is the term for algae that can be both motile and non-motile?
Flagellated and non-flagellated
Example: Ulothrix is flagellated, while some are non-motile.
What types of habitats do algae primarily occupy?
Moist, aquatic (freshwater and marine), stones, soils, and wood
Algae are found in a variety of habitats.
What is the characteristic feature of algae?
Chlorophyll-bearing
Algae are autotrophic and utilize chlorophyll for photosynthesis.
What is the significance of cytotaxonomy in algae classification?
It uses chromosome number, structure, behavior, and chemical constituents
Cytotaxonomy helps resolve classifications and confusions among algae.
What type of algae forms massive plant forms, such as kelps?
Marine forms
Marine algae can grow into large structures.
Fill in the blank: The reproduction of algae by fragmentation is known as _______.
Vegetative reproduction
True or False: All algae are motile.
False
Algae can be motile (flagellated) or non-motile.
What is the term for the simple, thalloid, autotrophic nature of algae?
Thallophytic
Thallophytic refers to the plant structure of algae.
What is the reproductive feature of Volvox?
Oogamous
Volvox exhibits oogamous reproduction with motile male gametes.
What type of algae is filamentous?
Ulothrix
Ulothrix is an example of filamentous algae.
